• Qosmio G20 blocked on JBOD in BIOS

  Hello

  I have a problem with the Toshiba Qosmio G20-109.
  The system does not start, the two hard drives JBOD (unable to start Windows).
  HDD1 - 120 GB
  HDD2 - 250 GB

  So I wanted to put the first disc HARD 1 1RAID-0 using the method described in the Manual: I entered the code 1 2 3 4 and I pressed Enter.

  The problem is that once entered the BIOS code remained frozen and blocked.

  I tried everything, I'm not despairing managing to install an operating system.

  I hope there is a solution.

  Hello

  If JBOD has been set in the BIOS, Windows OS could not be installed on this HARD drive except using the Toshiba product recovery disc. But I guess you want to install the system using another drive in Windows.

  To be honest, I not very well why the BIOS freezes and does not accept Mr. code it s certainly the right one: ENTRY 1,2,3,4

  But the issue is probably related to the HARD drive. How to switch hard drives in the Bay?
  Try to use the 120 GB HDD2 and the 250GB as HDD1.

  I also recommend you use the 1RAID-0 = HDD1 and HDD2 = JBOD
  Would be interesting how it works.

• Portege M400: Question on changing of JBOD RAID

  I have a M400 with driver SATA/RAID KR10I.
  I managed to have
  (a) a disk with RAID via BIOS, running / from XP SP2
  (b) a disc with JBOD via BIOS, running / from XP SP2 (available with external USB too)
  c) a clone of one) on a disc with JBOD (accessible with external USB too) but not starting not not by XP (error message STOP 7 or something like that)

  Not finding the important difference between a) and b) inside the registers to c) bootable too!
  Any suggestions?

  Hello

  you know that JBOD and RAID 0/1 are not the same. As you know, JBOD means "Just a bunch of disks", which has just PARTICULARY to do with the raid, because the HDD´s are treated as simple readers on their own, and when the raid then every disc is bounded somehow another disc, without worrying whether the disk is online or not.

  I think that the difference between the two modes on your laptop is, that the system doesn´t need to raid driver to run JBOD, but requires a when running on raid 0/1.

  So in your case, the problem is, you have an OS that has been installed with a raid driver and the system tries to load the raid driver but can't find it because there is no active RAID.

  Maybe you should read this article:

  http://en.Wikipedia.org/wiki/RAID

  There is no listed JBOD, but I think that if you spend more then 5 minutes of reading then you will understand my explanation.

  Or simply: JBOD is not a RAID mode. It s pure and simple HARD normal mode of a disk drive.

• Toshiba Tecra S3 - new SSD stuck on JBOD, cannot install windows on it

  I just got myself a Kingston V series 64 GB SSD drive, but I can't it is detected by windows installation programs.
  After looking around, I found that the Tecra S3 drives must be "1RAID 0" and not JBOD to activate windows to
  be installed on it. (unless you use the recovery CD, which I did not right now, even if I wanted to use it)

  I also found the "collar" necessary to get the BIOS to change when you get to 'run the creation '.
  is 1,2,3,4, [Enter].

  But here's the catch: + BIOS does not account for the string... +.
  I type the string, 1234, [Enter], and it cancels my desired, change as if I said NO and set it to JBOD.
  (if I don't type the string on the right, it comes out, but stays 1raid0 and "run the creation" is still there)
  I tried on one of my other drives and it worked fine, but for some reason this drive seems not wanting me to.

  I tried the USB drive (works fine) and the BIOS sees it for what it is, so that the drive works well (from my tests)

  Would be really appreciated any ideas on what to do now, I'm out of ideas on what I did not properly
  Thank you!

  Hello

  > I just got myself a Kingston V series 64 GB SSD drive, but I can't it is detected by windows installers

  Have you included the RAID driver in Windows before you tried to reinstall the OS?
  On the European driver Toshiba page, you can find the RAID driver to be included when installing Windows installation.

  Regarding the change in BIOS RAID;
  I m not very good, but it might be possible that you cannot change the reason the SSD RAID option.
  If other drives are working properly and that the RAID may be changed using a common HARD disk the problem is related to the new SSD drive.

  Maybe you need to update the firmware on the SSD drive to check it out.

• Portege S100: Unable to change JBOD to 1RAID-0 after replacing HARD drive

  I put Fujitsu SATA HDD in Portege S100-s1133 in the BIOS section of raid array that I couldn't able to change settings built in hard disk JBOD to 1RAID-0 form. When I made this change in the BIOS it couldn't recognize the RAID so I couldn't install OS.

  If someone knows this topic could you please help me?

  Hello

  Before you install the operating system, you must implement the RAID driver.
  The RAID driver you will find on the page of the Toshiba driver!

  Download and save the disk from the floppy drive. Then, connect the external USB FDD drive to the laptop. During the post-installation OS will ask you a raid driver installation. As I remember, you must press the S key.

  But can I ask you which CD you use? If you are using the recovery CD you n t need to install the RAID driver more because this driver already exists on the CD.
  It of necessary only if you install the operating system from the original CD of Microsoft operating system

  PS: Please also check you user manual. There is everything described in the simple way ;)

• Convert the ReadyNAS Duo v2 in JBOD

  Hello

  I have this old v2 of ReadyNAS Duo with two 1 TB drives that runs X-RAID.

  My system has changed and I no longer need RAID.

  Question:

  Is it possible, to convert the option X-Raid JBOD, which would be much more convenient for me...?

  Thank you very much in advance.

  Best regards

  Lody Claessen J.

  Sorry Mdgm...

  I totally forgot the fact, that the latest proposals just well you... apologies for this...

  As I said before... I'm getting really old... grin...

  In any case, I am also grateful for your help on this. !!

• JBOD Qosmio G20 - could not initialize the disk of 320 GB - 1RAID-0

  Hello, comrades Toshiba users,
  at first, I apologize if this question has already been answered, but I did not find the answer to my problem.

  One of my colleagues has a Toshiba Qosmio G20 with two 80 GB drives. Big 17-inch "surf-board-sized" computers laptops are not my cup of tea, but the Qosmio him quite well served.
  We tried to upgrade the two hard drives of aging in his laptop. With considerable experience in replacing the readers of the laptop, I didn't expect no particular surprise, but I was wrong.

  We tried to replace the original disks
  Bay 1: 80 GB Fujitsu drive, System
  2: 80 GB Fujitsu drive, data, RAID off the coast of the Bay

  with the new
  Bay 1: 320 GB WD Scorpio
  WD Scorpio 2: 320 GB drive Bay.

  The BIOS of the G20 is v1.30, the latest version. It recognizes new readers-, but one of the new marking as 1RAID-0 disks fails. After trying to "initialize" the 320 GB drive in bay 1 as 1RAID-0, on the third page of the G20 of BIOS, there is a disk activity, but the drive remains in JBOD mode.

  Unable to mark the drive of 320 GB 1RAID-0, I am unable to use the 320 GB drive as a system disk.

  If the original system drive is cloned on a new 320 GB drive, that it does not start. Starting XP * begins * but subsequently fails with STOP 0x7B - in other words, the infamous blue screen INACCESSIBLE_BOOT_DEVICE when the Toshiba RAID driver is loaded during Windows startup.
  Plain vanilla CD, of course with slipstreamed windows installation driver Toshiba, impossible rest. Installing Windows don't "see" drive in Bay 2.

  When the drive system is put in the high Bay and G20 is started from it, Windows XP starts correctly. The drive in Bay 1 is accessable from Windows, however, remains offline in the RAID from Toshiba console. If the start player in Bay 2 is not an option, too.

  A similar problem, where the owner could not install a system of 200 GB drive is described here
  Link: http://tinyurl.com/38wokw
  The owner, however managed to install a 100 GB drive and we have resorted to 80 GB of disk as a system disk and the only player upgrade in Bay 2 to 320 GB.

  I understand what happens when the disk is 'initialized' in the BIOS. Only brands of BIOS of Toshiba disk 1RAID-0, and it breaks down on 320 GB drive. I will refrain from expressing my opinion on this practice.

  My question is - if it is possible, how * manually * mark the drive of 320 GB 1RAID-0?
  Using a hex editor, dd or something similar is no problem. A partial answer would also know the disc more large size which * can * be marked with success under the name of 1RAID-0 at BIOS G20.

  Thanks in advance.

  Hello

  I m not 100% sure, what could be wrong by presumably 320 HARD drive size might be too big!
  How about the 100 GB or 120 GB hard drives?

  I think you should consider it because usually most of the BIOS supports a HARD drive size limitation and therefore not all sizes are supported.

  But note; using the configuration of 1RAID-0 (striping), met by the operating system size is twice more only if the smaller of the two HARD drives in RAID configuration. Using RAID-0, all data on both disks will be lost, even if it is training of two disks fails.

• NAS200 JBOD/LVM scandisk fails

  Hello

  as I set up my new NAS200, using disks 2x1To as a disc in JBOD mode, scandisk fails every time. Newspaper accessible via the administrative Web interface, a scandisk boot process leads to the entrance of the newspaper " LVM: ' (i.e. no results are saved!)" or "": scandisk failed '. " I use the latest firmware version 3.4R79.

  To try to solve this problem, I tried the following two:

  * I changed the firmware JAC4, connected via SSH and descended from xfs_repair, with the result of the SIN all suspended after xfs_repair for maybe 15 minutes running, but before he finished (after agno2).

  * I have detached the two discs of the NAS, attached to a PC, started using Knoppix 6.2 and made xfs_repair on the logical volume with no problems (in 40 seconds). I have attached the two drives on the NAS again, but still no scandisk initiated through the administration Web interface!

  What - what, there is a problem with the firmware?

  Are there other balls to distinguish who said to me why scandisk fails?

  Will I go back to JAC4 and run scandisk via SSH using different commands?

  I would like to regain my confidence to the NAS200...

  Welcome,

  Martin

  However, when I try to test on the NAS via SSH and xfs_repair, the process fails. So far, I thought that the process crashes, but now when I try again, it seems that, indeed, the xfs_process is killed by the operating system:

  The program can be killed by oom_killer the kernel if it allocates too much memory too quickly. If you had a serial port on the console, you would be able to see. Another way to see if this happens is to start /etc/rc.syslog (she normally doesn't start) and enter the command "tail-f var &" so that syslog messages are dumped to your ssh session where they occur. Don't forget to disable syslog again by entering "killall syslogd, klogd" and remove var because they eat RAM too!

  The time-out that I referred to has a possible timeout the web GUI can be used when it is waiting for the xfs_repair program. Of course, if you start the command line xfs_repair this applies to you.

  mbern wrote: too bad that they tested it with 750Go only, I wan't able to find a good official statement (on the Web page, in the manual). But I remember my dealer claimed the support of 1 TB, otherwise I would not have bought the NAS with two 1 TB drives. I also used the NAS in Raid 1 with drives of 1 TB without worries as above.

  The manual and the site doesn't mention that they have tested with 750 GB drives, they just mention (mentioned?) that drives up to 750 GB are supported. I guess they have tested with larger disks as possible...

  I use a drive 1 TB and never had no problem, theoretically there could be a problem if you install a disk that is longer than 2 TB (tera-byte binary) because this corresponds to the maximum value that can be managed by access 48-bit LBA. Most likely, the readers with a capacity of 2.5 (decimal) to claim are the first readers who won't be able to use 2 (binary) TB because of this problem. I have not seen all reports of anyone using the latter on a NAS200 yet.

• NAS 200 - two drives configured as a big disks (JBOD/LVM)

  Hello

  My first drive is full and so I put a second in my nas200.

  When I select:

  Two drives configured as a big disks (JBOD/LVM)

  My first drive will lose all the data?

  After that I backed up my data, I have merged the two discs.
  All data, users and directories have been removed.
  Thanks for the replies.

• Can WRT1900ACS use an external hard drive with disks in RAID 0, 1, or JBOD?

  Hello

  Happy new year.

  Is an external drive with more disks RAID 0, 1; JBOD compatible with WRT1900ACS?

  I have this idea to tie a big (6-8 TB) external drive and use the DLNA feature as an alternative to a computer as NAS and DLNA server. The external drive could be four 2 TB Western Digital hard drives in RAID 0, 1; JBOD. The boxes can be:

  - Western Digital my book Duo.

  - IB-3640SU3 - external case of JBOD 4 x with eSATA and USB 3.0 for disks 3.5 "SATA hard.

  I hope someone can help clarify if I have misunderstood something.

  Concerning

  Jan Rouvi

  Hello. It is not recommended to use this type of enclosure with the WRT1900ACS, since most of this is managed by software that are installed on the computer. The software will not be able to detect hard drives, whether they are connected to the router and the router does not have this capability to configure drives in RAID 0, 1, or JBOD. The configuration of the router storage tool is just very basic. If you really need to configure RAID 0, 1, or JBOD in terms of network, you must obtain a SIN.

• Dual bay JBOD integration: Volumes - Simple striped split vs vs

  The first option that I need to decide now is not put in shape, but rather if I want to set up as a Simple Volume, extending on Volume or Volume aggregated by bands. I demand to know: at what is Spanning and what is scratched? And besides, what is used for Simple? I know that I can get this information, but if you can relieve me of plowing through the mountains of unintelligible English composition work, so, I would be grateful: namely, what is the difference between a VOLUME and a PARTITION? and what it means to "mount" a volume?

  I have decidted to try an answer to these questions you asked, although I considered a risky business. Use of the Word may differ widely and wildly. I decided this because I was surprised to see a paragraph that uses the colon properly and correctly punctuated ' to know '.

  I start at the end: VOLUME and PARTITION. If the technical use of the terms in the jargon of computer geeks was the English standard, the PARTITION would be the place or address on the media which marked the end of a data structure. Similarly, the VOLUME would be data locations or addresses to which the data have been recorded. It is similar to the WALL and the ROOM. Use of the techniques of the terms did not differ much. When we talk of a PARTITION, we refer to a data structure that resolves the type, position and scope of a storage container. When we talk about a volume, an end to the storage location that have been defined for the storage of the data. Often, a drive letter is assigned to the volume. It is then a LOGICAL DRIVE.

  Note that many people uses the term PARTITION when they do in fact refers to the space between the partitions, actually a volume.

  It starts to get confused when you start under division in the PRIMARY and EXTENDED PARTITIONS. Suffice it to say that a primary partition refers to one set for its possible to maintain an operating system. He was confined to a volume that has been assigned a drive letter. The score of exrtended was intended for the non-executibles, i.e. data. Several volumes could be created within the partition, and more than one drive letter is assigned, one for each volume that is created. Each volume is a logical drive. Now-a-days, the distinction between primary and extended is blurry in use and (worse [?]), some operating system installers will allow you to install the operating system on an extended partition.

  Now, back to Simple, Spanning and striped.

  Simply referring to the fact that the entire volume is on a physical drive in either a primary partition or scope and size is fixed.

  Extending on refers to the fact that the fact that the partition is set to start on a physical disk and continue on one or several others.

  Striped refers to the fact that the contoller will deliberately write parts of the stream in defined segments, fixed size for each of the drives that are used for the volume.

  Now, to the subject of which simple, spanned, striped for use.

  Extending on is used especially when you have to have a very large space to store large files. On some systems, it is used as a convenient way to increase the size of a volume without requiring large data movement. Avoiding the passage of data avoids the time delay in particular with large files and the problem of data integrity of submitting the file for read/write operations.

  Interlacing is a form of Spanning. Covering appearance adds the notion of dealing with predefined segment length and balance the data across the physical disks. (I think here only to configurations using the entire disk for the game.) It is preferable to the covering simple (JBOD, for example) where data integrity is paramount. As implemented, it provides various means of correction and error detrection.

  Editing refers to the process of the operating system identify the drive and placing the instructions and data structures in place to enable disk reads and writes.

  My suggestions:

  If you need large and contiguous storage space, use a simple volume on a large drive. If you need speed, use the RAID 0 functions and make sure that you back up critical data frequenthy. For Windows, it is probably not a good idea for most users to use the readers more of 500 GB or 1 TB per RAID 0 set. Use the 'Quality of the company' readers, drives designed to operate continuously for long periods of time.

  I hope that gives you a starting point. Pease do not let it be the only place. You would be well served by reading and extensive consultations.

  Now, whether or not the discussion begins.... ;-))

• C460 JBOD - cannot install the OS right...

  Hi guys,.

  First of all, thank you in advance for your comments.

  I am a worker of cisco.

  A customer bought UCS C-460 with SSD of 12, 3 TB each. He got no RAID controller, this is just JBOD.

  I try to install RHEL 7.2 on it, as the user has requested [he asked 100 GB will go to "/" and keep him remains allocated United Nations]

  I have some problems with it.

  I installed it, but something was wrong... do not know what...

  installation seems fine, but after restarting, nothing would start...

  I suspect that some configurations via CIMC are bad.

  Please take a look at the screenshot and made me know and if it's fine, and if you can hit me with something that I may have been wrong.

  Thank you very much!

  Greetings.

  Because the startup disk is greater than 2 TB, you will need to use UEFI.

  Please make sure you have the following:

  • Start command mode is set to UEFI (not inherited)
  • Option rom for HBA slot or PCI slot the raid card is located, is activated.
  • 7.2 RHEL should correctly create a UEFI boot entry

  You may have to reinstall again, if it has not been defined in UEFI.

  Thank you

• Total capacity of the JBOD is not displayed

  Hi people,

  Only, we have installed ESX on a new Sunfire x 4170 server and connected with a Sunfire JBOD 4200 with 12 TB of capacity. We installed the adaptec disk utility to create RAID 5 and set it to build / check the status.

  Now when I do a fdisk - l disk/dev/sdc shows 9 to, however when I create a VMFS file system partition, it takes only 2 TB.

  I used the vmkfstools command to create a file vmfs3 system and it shows 2 TB.

  

  

  Any idea on what he may be wrong with my setup?

  Thanks in advance!

  You can create extensions, but Bein that it is indeed similar to the creation of a RAID0 array, you loosed on LUN you will lose all your data.  It would make more sense to create a single JBOD and slice in the dimensions more suited to your needs, calculate your VM disk needs and create your lun sizes appropiately.  If you store all your VMS; s on a single LUN you risk locking of SCSI with be serverly degrade the performance of your infrastructure

• Best configuration for Pegasus J4(up to 4 HDD/SSD's) - RAID or JBOD?

  I'm looking through a configuration of Pegasus J4 Thunderbolt disc for installation in first, until I can buy a more robust solution (probably Pegasus2). I am trying to determine what would be the ideal configuration for best performance on the casing of the drive. I apologize for my ignorance, but from the point of view of creation, that I'd better be using 4 small SSD (120-240 GB each), set up as JBOD? or should I use 7200 rpm disks, configure in RAID 0? Connection via Thunderbolt.

  Thanks in advance.

  Jordan

  See Page Tweakers - External Drives

  If you read carefully, you will notice that 2 SSD is max Thunderbolt connection, then add more SSD does not improve performance at all, will cost more.

  Four conventional disks 7200 RPM in raid0 will be released also (almost) max the Thunderbolt bus, but are much cheaper and offer much more space. JBOD is not desirable, because of lagging performance.

  4 x 1 TB HARD drive @ $70 = $280 less than 2 x 256 GB Samsung SSD Pro 840 @ $220 = $440

• Using a T610 to a JBOD

  I have two servers T610 with integrated PERC 6 / i controllers.  I try to use these for Microsoft scaling of file servers and need to add SAS drives, but present them to the BONE as SAS RAID not.  Is this possible?

  No, the PERC H700 6 do not support JBOD/no RAID. The only way to use the disks individually on these controllers must each set up as a RAID 1-disk 0. For true amp, you will need the H200 controller.
