Unable to mount VMFS after rebuilding partition table

[Spiffyjimmer]

Hello All,

I am currently working on the issue with two vmfs files that were wiped when a raid card was swapped.

So far I have rebuilt the partition table on the drive and can see the partition from the devices, though I have been unable to mount the partition and when I try adding the drive the only option i have is to wipe it out.

Currently I am running a data recovery on one of the drive but due to time constraints and working to repair the drives to bring the system back online faster.

At this point I thnk the issue is with the lvm but i am out of my depth.

Any help would be greatly appreciated.

Best,

Justin

To add to my original post.

The two drives which ran into issues are both 500 GB SSDs.

To rebuild the partition I ran the following commands.

partedUtil getptbl <Device Path> - which gave me the following output

gpt

62260 255 63 1000215182

I used the above information to calculate the end sector using the formula (62260*255*63)-1=1000206899

Next I ran the following command against the problem drive:

partedUtil setptbl <Device Path> gpt "1 2048 100206899 AA31E02A400F11DB9590000C2911D1D8 0"

With this done the output finished but shows the following

gpt

0 0 0 0

1 2048 1000206899 AA31E02A400F11DB9590000C2911D1B8 0

Next vmkfstools -V which didnt mount the drive.

I then swapped the last sector for the data in the partedUtil getUsableSector which had the same results as above.

Currently my best guess is that I have the partition table wrong though the partition looks to be present now on the disk.

In my travels around the internet I did see Ulli ask about the lvm from the Voma command which reports an issue with the magic number though I am unsure if this is a red herring or not. I am continuing my research and will update should I make progress.

Best,
