• Retrieve VMFS partition table... help.

  Hi all

  This morning, when I boot ESXi 4.0.0 I found lost a VMFS volume. By default, my drive has two partitions. I tried to recover the second partition with the instructions on the forum, but it was still not working.

  Please help me!.

  This seems really odd. Do you have all the partitions on these 4 discs when you first installed ESXi?

  What version of ESXi you originally installed (3.5 or 4.0) in the case where that this system has been upgraded?

  Please after the release of fdisk-lu for all 4 disks in the system.

• VMFS partition table corruption? Need help to retrieve data

  My House ESXi 5.1 was installed on HP Microserver G7. Hypervisor on USB-flash, datastore on Adaptec 3405.

  After some problems of power electro Microserver is will not start and I have chosen to build the new server on Microserver Gen8. I moved Adaptec and disks in the new box, installed new ESXi 5.5 U1 (HP image) on USB and after reboot did not store data :-(.

  After some research, I found that ESXi is not see any partition table on this raid array:

  
  

  partedUtil getptbl /vmfs/devices/disks/mpx.vmhba2:C0:T0:L0

  unknown

  728422 255 63 11702108160

  BUT! I tried to start the server of linux liveCD with vmfs-tools 0.2.5 installed partition mounted with vmfs-fuse and able to see the data! But cannot copy all important vmdk (see below).

  debugvmfs is also show me some useful information:

  Volume Version: 14

  Version: 54

  Label: STORE

  UUID: 4f2ac538-58c181cf-arms-441ea13ee615

  Subblock size: 8 KiB

  County of FDC Bitmap: 64

  and it's very strange

  debugvmfs/dev/sda1 see the lvm.extent [0]

  Device: / dev/sda1

  UUID: 4f2ac4da-8de4b166-a-441ea13ee615 848

  Size: 459.99 GiB

  NUM. Segments: 22319

  First Segment: 0

  Last Segment: 22318

  
  

  because I don't know that I don't create scopes.

  
  

  Also, there are two vmdk files on more than 256 GB data store and it cannot copy because of the limitation of vmdk-tools :-(.

  
  

  I tried to do a magic (like this - partedUtil setptbl "/ vmfs/devices/disks/mpx.vmhba2:C0:T0:L0" GPT "1 2048 11702099429 AA31E02A400F11DB9590000C2911D1B8 0""), but without success;-(.)

  
  

  All the suggestions, guys?
  

  Finally!

  Found that was an "Intel VT - d" enabled in the BIOS. After disable it everything is cool.

  It looks like Adaptec 3405 working wrong with it. Will try to change it to P222.

• All gone VMFS Partition tables! on LUN

  Today, we had a 20 TB of data problems and all partition tables VMFS got blownen now. All ESX servers were not able to see the data stores. Everything is back to normal now, but I have a question, not even a VM has stopped working? How is that possible? VMware said eventually they would have all the blue screen, but the LUN was down to 2-4 hours and not even a VM is down, we have more than 300 + VM can someone explain how it worked?   I guess they were running in the memory cache and depending on the amount of data is being written depends on when they started bluescreen? How does it work?  I am pleased, that was the case...

  Hello

  Discover the recovery VMFS partitions for assistance. SMV will stay running because they know where they write on the disc through a caching mechanism. The disk data were not deleted, only the partition table.

  Why don't you ask before if you are unsure about the procedure?

  Run the two commands after that other was a bad idea

  Here's what I do now:

  create a volume dd image and store it somewhere safe

  1 delete the partition again - once again using partedUtil
  2 check the partition table and make sure it is clean
  3. recreate the partition with the command B
  4. start system with a USB of UNUSED ESXi or even better with a LiveCD ESXi5 to rule out any missmatches signatures
  5. try turning up the volume manually, if it is not detected automatically

  If this does not work

  1 delete the partition again - once again using partedUtil
  2 check the partition table and make sure it is clean

• Assistance button works do not (= does ' t start VAIO Care Rescue) after having lost and recover the partition table / MBR

  Hello

  For some reason that I lost my patition table but I was able to get it back and I'm rewriting MBR. I'll be back all my partition and files contain the VAIO recovery partition except files on the operating system partition ("C:\ »). It's an unformatted partition. VAIO Care rescue didn't work so I had to format "C:\". "and reinstall windows 7 and now all is good.

  I have VAIO Care Rescue. I think that it is enough to change the partition table / MBR. What exactly is the problem and is it possible to fix the problem of button Assist?

  
  And if one removes all xxxx (include VAIO Recovery) and creates new ones, is it possible, software or image of the recovery restore partition and Assist button start VAIO Care Rescue?

• Partition table / no entry of safe mode

  HERE'S MY QUESTION:

  I'M TRYING TO RECOVER MY XP DESKTOP COMPUTER. WHENEVER I TRY not to enter MY "SAFE MODE" VIA THE XP CD I GET NO PASSAGE. NORMALLY I CAN GO THROUGH LOG BUT I'VE NOW DAMAGED A PARTITION. I USED THE HELP FILE (FIXMBR) HERE IS THE MESSAGE I HAVE,

  * THIS COMPUTER SEEMS TO HAVE A NON STANDARD OR INVALID MASTER BOOT RECORD *.

  FIXMBR may damage your partition tables if you continue (of course I did). This could cause all of your scores on the current hard disk to become inaccessible.

  If you have problems to access your drive, DO NOT CONTINUE (of course I did)

  Are you sure you want to write a new MBR?       (of course I checked yes)

  Then... If I'm screwed?   I have to buy a new hard drive?   I can solve this problem?  Can I use the old as a ghost player to get my files?

• Recovery raid-formatted vmfs partition

  Faced with a situation where the vmfs volume has been formatted through (non-destructive, that I hope) raid controller

  ESXi 6, improved 5 so I guess it was a TPG

  I could have esx5 installed on this raid volume so the vmfs volume is not at the beginning. I tried to use vmfs-tools but don't like that the partition is not formatted.

  Any help would be appreciated - how can I recreate the partition information?

  Thanks - Joe

  You should always use the getUsableSectors command to find the endsector - it's probably a good idea to use an ESXi 5.0 feature.
  Or tell me the exact size of the volume and I'm trying to use a vmdk in the size of your raid to get the value.pe

• It is possible to expand a vmfs partition?

  Well, here's my problem, I have 2 esx servers, connected to DS3400, people who originally this set up only bought 4 disks and created a raid 5 1.6 to VMFS partition. The guy he filled and I was running out of space.

  So I bought 2 more disks. I added the readers to the controller and added to the raid, creating a bigger raid.

  I returned in vsphere and saw that there was free space and I tried to extend VMFS partition but I couldn't? I thought that I was not supposed to create a new measure.

  In my frustration, I said F and I just created a second logical drive, formatted as VMFS and added and moved some of the VMm on the new 800 GB partition.

  Now, I bought 4 records more than daughter upward the ds3400. I'm trying to add them to the table.

  I need to make the a VM on the origial 1.6 TB of greater. So I don't want to add a third partition, instead of this I would really be able to extend the partition of 1.6 to 3.2 to with new readers, I add.

  Does anyone know how or if I can do this? Its going to take some time to add the new disks and I need the extra space pronto.

  When I'm in the IBM Storage Manager I see

  Unconfigured space 1.2 to (always adding these readers)

  RAID 5 2.8 TB

  -Original DS (1.6 TB)

  -1 (837 GB) second one I did

  -Release the 418GB capacity (one of the 3 new discs add)

  Once I get the other 3 dirves, I'll have another 1.6 to release capacity on the raid. This is where I'm stuck, how to use that to extend the original 1.6 to vmfs.

  Thank you people a bunch.

  It is possible to expand a VMFs partition - but the problem is that you can not access a logical unit number is greater than 2 TB - 512 B and the largest virtual disk is the same 2 TB - 512 according to http://www.vmware.com/pdf/vsphere4/r40/vsp_40_config_max.pdf - using extensions you can create a volume of 64 KB-16 TB per individual LUN stacking

• Upgrade to ESX4 without VMFS partition

  Hello, I have a u2 ESX 3.5 with a tip of SAN a GB 20 LUN, without the local disks to the ESX 3.5, it is fine, but I need to upgrade to ESX 4 with VUM and to do this, I need to a data store VMFS 9.2 GB for the service ESX4 console.

  The 20 GB partition table. LOGICAL UNIT NUMBER.

  / dev/sdx3 9.2 G 1.2 G 8.0 G 19%.

  / dev/sdx1 97M 29 M 64 M 29% / Boot

  / dev/sdx2 5.2 G 121 M 4.8 G 3% / opt

  No 132M 132M 0 0% / dev/shm

  / dev/sdx8 985M 75 M 860M 9% / tmp

  / dev/sdx6 2.5 G 494 M 1.4 G 27% / var/log

  If I want to reinstall ESX 3.5 year create partitions and a data store vmfs 10GB for 4 ESX service console, I can restore the configuration if I only backup the directory "/ etc" and then copy over the new ESX 3.5 for the upgrade with VUM?

  Thank you.

  may be a stupid question, do you have the provision to add another 10 + GB of LUN\Disk? If so, create VMFS volume on this disk\LUN and use the same for COS vmdk during the upgrade.

  By the way, where is your current VMFS data store is located? It is not required to keep the vmdk cos in a Local data store, you can keep it in warehouses of data VMFS3 except SIN and SWiSCSI.

• ESXi 3.5 - clean installation, it will wipe existing vmfs partition?

  So let's say I have a U3 3.5i ESXi server is installed on a single table of RAID 5.  I want to do a clean reinstall using U4.  When I installed U3 it parititoned discs automatically, so when I go to install U4 will be it preserve the current vmfs partition or is it delete and then recreate a new?

  The reason I ask this is just in the preparation of a time where a firmware update could possibly fail (do not assume that it will be, just want to have a plan in case something goes wrong).  Just want to be sure I can do a reinstall with/without losing existing virtual machines.  I'm not worried about having to reconfigure everything - not a big deal.

  Thank you!

  You have the ability to clean any vmfs partition, or leave them alone.  It is up to you to destroy the existing, which you do not want if there's vm is here, or leave them alone.

• ESX host with local storage recommended for the host partition table?

  Hi all

  I know that the best practical partition table should look like this:

  Mount Point	Partition	Size	Description
  		/ dev/sda (primary)
  / Boot	ext3	250 MB	Change of extra space for upgrades
  N/A	SWAP	1 600 MB	Change the maximum size of Exchange service console
  /	ext3	5120 MB	Change of extra space in the root
  		/ dev/sda (Extended)
  / var	ext3	4096 MB	Create partition to avoid an overflow of root with log files
  / tmp	ext3	1024 MB	Create partition to avoid an overflow of root with temporary files
  / opt	ext3	2048 MB	Create partition to avoid overfilling root with the log files of VMware HA
  / Home	ext3	1024 MB	Create partition to avoid an overflow of root with agent / user files
  	vmkcore	100 MB	Pre-configured

  However with a system with local storage would you set it up the same way, and whatever it is must be amended to change to get ESX to write log files to the different partitions?  I would like to configure it for future expansion for when the enterprise package is configured.

  Yes, I would set up the same way with an ESX with local storage server and nothing needs to be changed for the vmekernel right at the partition/var - unless of course you want to write to a log server that you need to change a configuration file to point to the server logs.  If you talk to the ESX Enterprise license you willnot have to change partiition table-

  Also on something else if you don't have a SAN/NAS storage you will also need to create a VMFS partition on the local data store to host your virtual machines

  Hay guys,

  I wanted to start my Toshiba Quosmio x 500 - 14W PQX33E (Product Code), but the only thing I found on my desk: invalid partition table.

  In another Forum I found a threat, which means I have to restart my computer. So I tried a Reboot Cd, but found nothing. Then I tried to call the Call Center of Toshiba, but they are closed...

  For me, is the Toshiba Service miserably and I hope that some guys from the Forum can help me.

  Thank you

  Hello

  You must install the operating system once more.
  Invalid partition table means that something is wrong with the HARD drive and the operating system cannot start.
  So if you n t have a recovery disk, you must order one:

  PS: I made good experience with the Toshiba service comparing the service with another laptop from the manufacturer I have to say that s OK and I meet a lot of people who said that other manufacturers are not really better
  Which; s my opinion
