/dev/sda mount is missing

Hi,

 

I am facing the following issue after a system reboot to power issue,

I am using XenServer 7.6, which is not showing the SR in Xenceter.

using lsblk -f cmd I am able to see the SDA list and I don't see any output for pvdisplay or lvdisplay.

So I thought that vg is corrupted so tried to recover using "vgcfgrestore vol_grp --test -f /etc/lvm/backup/VG_XenStorage-c5645c0f-5a11-3ab1-e220-abd18a01aab0" getting TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated.
  Couldn't find device with uuid 1m783S-mATE-T3TF-Pug8-jaNS-e3v3-9DHlmc.
  '/etc/lvm/backup/VG_XenStorage-c5645c0f-5a11-3ab1-e220-abd18a01aab0' does not contain volume group 'vol_grp'.
  Restore failed. error.

 

If anyone has an idea on this error please let me know.

Thanks in advance.

HI,

 

Somehow we have recreated SR and can see the disks under SR--Disks. However, I am unable to see the VM's or VM list.

strangely I am not even able to see the default templates on the server when I go to create new VM.
