VOMA - LVM Major or Minor version Mismatch, Failed to Initialize LVM Metadata

Using ESXi 6.0 with the free version of vSphere.

I simulated a short press of the power button via iRMC while a CentOS VM and a Windows VM were up. The host proceeded to shut down. It took a bit for that to happen. I expected that the VMs would also shut down cleanly, but I was wrong.

Apparently, everything still works, but the Windows VM reported an unclean shutdown.

So I decided to check the host file system with VOMA. I have only one datastore spanning only one extent.

To that end I ran

voma -m vmfs -f check -d /vmfs/devices/disks/naa.6005xxxxxxxxxxxxxxxxxxxxxxx

voma -m vmfs -f fix -d   /vmfs/devices/disks/naa.6005xxxxxxxxxxxxxxxxxxxxxxx

Both commands yielded the following results:

ERROR: LVM Major or Minor version Mismatch, Not supported

ERROR: Failed to Initialize LVM Metadata

VOMA failed to check device : Not Supported

Total Errors Found:     0

Total Errors Fixed:     0

Total Partially Fixed errors: 0

Kindly Consult VMware Support for further assistance

How can I get rid of this error?

Thank you.

Hello,

Is this Datastore consist of extents?

esxcli storage vmfs extent list

Regards,

Mario

Bumped into such issue on ESXi 6.7 and 7.0.

Even:

  • removing and creating the datastore on ESXi
  • reinstallation of the ESXi
  • removing and creating the VD disk in the RAID controller (we use LSI 9360-8i) and installation of the ESXi

didn't help.

 

The problem has been solved after these steps:

  1. Creating a new VD via the controller
  2. Erasing the VD via the controller
  3. Creating a new VD and get full initialization done via the controller
  4. Installing ESXi

 

Hope this help to anybody.

you need to specify the partition number to execute correctly

see KB https://kb.vmware.com/s/article/2036767 

voma -m vmfs -d /vmfs/devices/disks/naa.00000000000000000000000000:1 

Where: naa.00000000000000000000000000:1 is the LUN NAA ID and partition to be checked. Note the :1 at the end. This is the partition number containing the datastore and must be specified.
