Attached data recovery problem size Raw LUN


We have a problem with our unit of recovery to Date.

We have a matrix of about 12 TB discs intended to save our VMs.

So, I try to join VM recovery given as a raw LUN.

I saw 10.9 TB plug in recovery. try to format... it seemed to me that it works.
But when I ride it, it was presented as a 2 TB drive.

Umount - 10.9 Tb
Mont - 2 TB

The next step... I have connected to the computer of data recovery (I mean it's just a CentOS behind). And try to make a hand partion using parted and mkfs.

parted worked well (with TPG as the label).
So I launched
mkfs.ext3/dev/sdb1

It took a lot of time, went up to
"Writing Superblocks and filesystem accounting information.
and it seems that it crashes.

mkfs still present in the process, but it seems that it do nothing.

It's probably a problem with the ext3 file system.
But
(a) it seems I might have an ext3 file system larger than 2 TB.
(b) ext4 is not available on CentOS of data recovery... so what could I do?

So... maybe someone has a tip for this problem?

Thank you very much.

P.S.: Just for the record, we have 3 ESXi5 host with vCenter 5.

I'm not 100% sure why you see the wrong size RDM, but make sure you read the Administrators Guide.

of http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vmware-data-recovery-administrators-guide-20.pdf

Data recovery is designed to support deduplication stores that are up to one terabyte of size and each appliance backup is limited to the use of two stores of deduplication. Data recovery imposes no limits on the size of the stores of deduplication, but if the size of a store exceeds a terabyte, performance may be affected. While data recovery imposes no limits on deduplication store size, other factors limit the actions of deduplication. So, the stores of deduplication are limited to:
-500 GB on CIFS network shares
-1 to VMDK and RDM

  • SSHD Toshiba MQ01ABD100H - Firmware / data recovery problem

    Hello!
    I have the mission critical data on a MQ01ABD100H of Toshiba to SSHD which was in a Sony VAIO for less than one year who decided to stop working from one day to the next. All I care about is the data. A professional data recovery company apparently reputable rated player, told me that it was a "mechanical failure", said they could recover the data and gave me a quote of $1500.00. A week later I was told something different; They said the platters and heads seem to agree and the problem seems to be on the circuit board and/or flash drive, and they didn't know how to recover the data. They told me that they have consulted Toshiba too. I asked them if they replaced the pcb Board and they would not tell me or answer questions more. I have the drive in my hands and am looking for options. I really believe that my data is recoverable if the trays are okay, right?

    Here's what I know for sure; the bios of the machine of Sony VAIO Windows 8.1, correctly recognizes the drive. However, it does not start and is not accessible or recognized with cmd prompt Windows 8.1 UEFI options. The drive is not encrypted. After putting the reader into an external enclosure and its connection to another Win8.1 machine, the player starts with no extreme sounds of survey. Slowly, she clicks a few times as if the heads are looking, but then calms down and keeps running quietly. I have installed a Data Rescue PC3 software that recognizes the drive and its attributes correctly but can't read or clone. I have the Partition Wizard software mini tool, which recognizes the drive correctly, but shows the drive as being unreadable.

    That's what I'm trying to do. I'm looking for a donor on mine, with the same model drive, date, firmware, site, number of PCBS, hard drive code.

    Now, here is my unknowns and I appreciate everyone a preview with these. If I change the pcb edge myself, I need still more likely transfer the firmware for the new Board of Directors, even if I try it without doing it. I don't know where the firmware is stored, is there a rom chip or is it stored in the Flash Player. I'm not certain if, with this model of SSHD, if this can be done with replacement of the chip or the software? If it is stored on the Flash drive how is available independent of the HHD part? Must the reader Flash itself be harvested? But what happens if the flash player is bad, how can the firmware ever be recovered? Any ideas anyone? ... other than myself shot in the head, I'm kidding. I think that this may be a common problem that will often not resolved.

    I have the drive in my hands and am looking for options. I really believe that my data is recoverable if the trays are okay, right?

    I am not an expert but if applications cannot access the data and cannot read data from the SSHD then you will need professional help...

    I found the storage Toshiba page where you could get details on this SSHD

    }, 'VirtualMachineConfigSpec' );
    

    Someone knows how can I get the type of backup data.

    In perl, you can use "ref" to determine the type of thing that is referenced. Here, it will be as follows:

  • Satellite L850: Drive HARD Firmware problem prevent data recovery

    Am a little confused and need a simple explanation
    My HDD L850 died under warranty and was sent to the people of data recovery to recover the data before entering new drive under warranty.

    I am told that my hard drive has a fairly unique combination of firmware and the drive that prevents the recovery until they get this firmware. Now 6 weeks after it happened I stll wait.

    Someone in support could explain to me in simple terms, why this firmware is the problem cause and so far can only be obtained by your partner data recovery company?

    Hello

    I think that you will here get a correct answer, why the people of data recovery needs of these packages since it is a user forum.

    But to my knowledge all the 2.5 hard drives and SSD drive supports various firmware.
    These firmware tells the hardware how to interact with the operating system.

    It seems that people in data recovery needs these packages in order to get access to the HARD drive, and I presume, without the compatible firmware, it is not possible to recover the data.

Ok.  I make it work with both my VMC - one with the service pack and the other without.  My OS updates have been loaded in early December, so I don't see how this could it be.  I searched and found this problem has come up before, but I have not found a solution.  I made NO changes to my HTPC.

    I installed the latest round of updates (Ultimate) of Windows Vista and it apparently burst Netflix in WMC.  Now, I get the error:

    "There was a problem of data recovery. Make sure your internet connection is working and try again. »

    Internet works on the machine.  I reinstalled Silverlight (v4) and Netflix for WIndows Media Center.

    How to diagnose and repair the problem?

    Thank you!

    Keith...

    Sorry for the delay, but I've been busy (in my free time) trying to get this to work.

    I gave up trying to resuscitate MCE and installed a brand new Windows Vista Ultimate Edition with Service Pack 2.  After apply all WIndows patches and installation of Silverlight, I have the "Netflix" element in MCE.  He invites me to install, what I'm doing.  However, every time I start MCE and go to Netflix, he tells me to do reinstall - no login screen.

    I tried all the "mcupdate" article and then supported your steps above, but no go.

    I did this twice, so it wasn't just a fluke.  Apparently, the part of Netflix to MCE is not detect the plug-in that it installed.

    Any thoughts on what to do then?

    Thank you again...

    Keith...

    Later: I ran "mcupdate" after the steps you suggested, and now Netflix is gone again!

    Later: same problem on my other computer running MCE and Vista.  I don't want to mess up this computer so I left as what.

    Later: opening of a new post on problems become Netflix to work with a clean install.

  • How to backup VMs that have RAW LUNS attached with TSMserver v5.5 and TSMclient v6.1 in VCBproxy in a task (backup script)

    Hallo

    I have several virtual machines that have RAW LUNS attached to them.

    Question 1: Is there a way for me to use (free LAN) save those VMS with VCB + TSMserver 5.5 + TSMclient 6.1 - in mode (an automated task - script), which local VMDK disk backup is backup with FULL-level and fasteners LUN RAW to the VM backup files of the virtual machine level. Does the solution support?

    Question 2: Is there a way in a task (separate in the 'pre' and 'post' script) as a single disc with vcb backup - for example when VM have a disk VMDK more attached, only a VMDK disk backup for is a primary partition on a virtual machine?

    Note: Backup free LAN for backup of the VCB proxy any type (level FULL or FILE) is correctly and fully functional.

    Hello

    Question 1: Is there a way for me to use (free LAN) save those VMS with VCB + TSMserver 5.5 + TSMclient 6.1 - in mode (an automated task - script), which local VMDK disk backup is backup with FULL-level and fasteners LUN RAW to the VM backup files of the virtual machine level. Does the solution support?

    If the RAW format is really a ROW then you can do a virtual RDM and Yes, VCB will save help file or full. If she is not a ROW but a RAW, then only the VMDK can be saved via VCB.

    Question 2: Is there a way in a task (separate in the 'pre' and 'post' script) as a single disc with vcb backup - for example when VM have a disk VMDK more attached, only a VMDK disk backup for is a primary partition on a virtual machine?

    Not only a single disc that I saw that it's all or nothing. If you don't want to VCB to backup a drive, you can mark it independent or if it's a RDM make non-virtual.

  • Problem strange RAW corruption on master + backup hard drive

    Hello

    I am a professional photographer and I have a problem of confusion with corrupted pictures. Although this technique is probably not Lightroom problem, I cannot think of a better place to ask and part of the issue is related to managing files in Lightroom. The problem coincided with the release of Lightroom 2015 CC-1, but I can't tell if it's somehow connected.

    In short, a month after the download and processing a large amount of RAW CR2 photos, many of them have corrupted. I only learned this yesterday when I tried to export.

    Corruption looks like this: http://www.justphotos.ca/errors/MEM404067.jpg

    The photo is not mine, but the problem is similar. Part of the photo seems normal, and the part is destroyed. Ratio varies.

    I performed following diagnosis:

    • CheckDisk from the Windows Explorer, including a review of surface - no problems found
    • inspecting SMART disk information (via Crystal disk Info) hard - the player gets in the 'good', without the obviously alarming parameter (although I'm no expert)
    • checked the RAM with memtest86 - no error
    • Rootkit and AVG scan antivirus - nothing found
    • Explore and Lightroom can normally handle files (copy, read, even develop), it's just that they are corrupt

    Most important question first: does anyone know what can cause this kind of corruption and avoid the detection of all tests mentioned above? What to do about it?

    Without doubt, if there was a problem with hard disk SATA cable or the motherboard

    — — — — — — — — — — — —

    Here's a bit more background where things get strange, and where someone with LR knowledge might be useful.

    The disk in question is a 4 WD to with tens of thousands of photos. I checked a large number of files at random, and so far found corruption in only two, chronologically one after another (which may mean that they are adjacent on the hard disk, but it can also not if she was significantly fragmented). There may be others, look at a RAWs after deleti

    Photos were taken a month ago. I copied them manually a master drive (internal) and a backup drive (external USB, that I connect it only for backups). I looked at all the photos in Lightroom and post processed a few hundred. They were all very good. After that they justsat there for a month with no activity and no display (IE. "I can't know exactly when they are corrupt).

    After post-processing, I used a software to synchronize folders of the master and backup drive. It copies the new files, existing files that are new or that have a different file size.

    Next question is crucial, so please help me shed some light on this subject. Lightroom IN ANY WAY change the CR2 files themselves? I know that it creates XMP sidecars. But it in any case never changes the master RAW file?

    This is important because I know for a fact that impeccable original RAW files copied manually on the backup disk. The synchronization software is not copy of corrupted files from the master disk unless they were changed somehow.

    As far as I know, classic disk corruption is invisible to the OS or file system - when it occurs, file size or date modified are changed - only the physical data of origin on hard disc tray.

    It may be of academic importance right now, but I need to know to change my backup solutions for the future.

    Thanks for your suggestions!

    I use Windows Explorer for initial backup (when files are fresh off the memory cards) and later Karen's Replicator. Basically it compares just the folder main and backup with one set of rules. In my case, it replicates destruction and seeks new files and the changed files (by date and file size).

    I can highly recommend FreeFileSync because it offers much more more available capacity and reports to the Replicator from Karen. After having compare them initial source of backup disks it provides a detailed report of the files to be added, deleted or updated. You can easily see the files and folders that will be removed or updated during a synchronization operation backup and do a quick test of validation.

I guess the problem should be with the plates, because the files were not changed at any time for other parts of the chain could damage the flow of data through the reading and rewriting. But if Windows CheckDisk could not detect even a problem with the surface analysis, how plates can be the culprits?

    All readers use control during the reading & writing data CRC to confirm the integrity of the data. Also with the degradation of the base of data errors would show in one or more of the INTELLIGENT information displays. Your car has no. It is quite possible that you encountered an error of intermittent system by reason of overloading, overheating or low supply voltage, etc. You can download the free SMART PassMark DiskCheckup utility and run the self-test extension.

    You can use the free HW Monitor to check the system of base temperatures, voltages and fan speeds. If you have run Memtest86 only and not MemTest86 + you can run. Unfortunately, these memory testers all run in stand-alone mode, without the operating system loaded. This may seem like a good idea so that you can access and test all locations of memory, but he may not reveal memory problems that occur only with memory loaded and running in the OS and applications.

    If you encounter other errors or system problems and two imported image files folders are affected it may have been a stroke of chance-event. The best suggestion that I can provide to help prevent it happening again is NOT move or rename files or folders after they are imported into LR. Using LR rating Keywording and Collection of tools and the filter bar, to organize and locate your image files, not folders. An inverter is also good protection against loss of same power infrequent or brown-outs.

  • Move a virtual machine that has a raw lun mapped to SAN

    Dear all,

    I need expert advice for this case. I have a virtual machine on a host with esxi 4.0, but due to many machines same virtual host we are experiencing memory problems and have decided to move this virtual machine to another host with less VM and less use of resources.

    I plan 1 HR time to perform this task, this virtual machine have two drives one windows partition and the second 20 GB as mapped lun on SAN. So when you move it to another host, what I'll do is tap to stop the virtual machine, go to another host and storage switch to VM folder and add the VM.vmx file to add it to the inventory of the new host. What about the case of raw LUN mapped, how to take care of it.

    Please advise, it is little urgent.

    Thank you

    I guess there is no vCenter at stake here and you have no option for vMotion? The RDM, I would like to stop the virtual machine, detach the RDM LUN, migrating the virtual machine and re - attach the RDM.  As long as the two hosts can see SAN/RDM, you should be good with that.

  • Understand planning for VMWare Data Recovery

    Hello

    Under VSphere 4.1.0 with vmware data recovery, through Assistant I generated a planned not here are the features in the attached screenshots backup task.

    I came back the next day, I saw that the backups are done at 8 in the evening (20: 00), but no time, it is written in Wizard I see slots... so where can I see the task of recording time son? and/or what are these slots in the end?

    Hey North Carolina,

    It is precisely one of the problems of VDR: you don't master's degrees not starting backup time! You define time slots during which the backup can take place. Then, the VDR system decides alone when launch the backups. The only thing you're on, it's that no backup takes place during the time slot prohibited (in grey in interface).

    Good luck.

    A +.
