Question

Accidently Deleted VMDK Disk File!

Asked by: jjdurrant

The VMDK file on one of our VMs was accidently deleted via the command line on the ESX host. This wasn't the boot parotion, but a data D: drive.

The data drive VMDK actually resides on a LUN. Is there anyway to recover? The LUN shows 100% free space. But I would think the actual raw data is still there. We have a backup, but it is several months old. LOL

Thanks!

I gues you would need an undelete program.

Plenty are available, but you need to be very carefull, since you would prefer one that will NOT write to the data partition, but preferably somewhere else.

I hope this helps !

Sorry to say that you're out of luck. There is no 'undelete' functionality in the VMware tools, and I don't believe there are any undelete tools out there that understand the VMFS file system. You'll need to recover from a backup.

On the other hand, VMware support *may* have a tool. It's worth logging a call and asking the question.

VMWare was no help. We had to have Ontrack do a block level restore from the SAN. You do not want to know the cost involved!!! LOL

I can't believe EMC has no tool to do this!

 

by: meyersdPosted on 2007-03-13 at 03:38:25ID: 18708901

Glad to hear that you could get the data back. I'm impressed that Ontrack succeeded.

Probably a good time to set up AD authentication on your ESX servers and turn off root login from ssh. A non-root user would not have been able to delete the vmdk file without using sudo or 'su -' first. Also make sure that rm is aliased to 'rm -i'.

I've experienced a similar case. My ESX4.0 told me, after a reboot, that my disk had no VMFS ?!? I couldn't find any data on the disk. There was a partition but no data/fs. It was not that hard to use a undelete/filerecovery application to do a block by block search on the disk and it found all my NTFS partitions and at least all my essential files... Didn't try to restore everything since i didn't  know how to make the restored partitions bootable.

 

by: ndennyPosted on 2011-03-11 at 06:53:45ID: 35109198

hi merLRmindre,

Similar issue here so was wondering what application did you use?

thx

 

by: merLRmindrePosted on 2011-03-14 at 00:50:09ID: 35125964

Hi, I used Active@File Recovery from LSoft. But I think you can use almost any file/partition recovery tool. The main thing is that you ensure that there is no writing on the disk before you have recovered what you want.
