Earlier today we had a working Prox 4.2.2 installation There was an issue with the BBWC on the RAID that was fixed by the data centre.
After we restarted the machine (and apparent successful shutdown of the VM) we found that the VMs failed to start with the type of error as detailed below. The machine was a 'default' install of Prox with lvm-thin Each of the 3 VMs shows the same type of error with "Could not open ....disk-1 No such file or directory" AFAWAA nothing had been touched with respect to the LVMs The link for the 'disk' does not appear in /dev/pve (though I believe I saw one in there prior to the machine being restarted) file=/dev/pve/vm-701-disk-1 root@pve:~# ls -l /dev/pve total 0 lrwxrwxrwx 1 root root 7 Sep 1 02:25 data_meta0 -> ../dm-3 lrwxrwxrwx 1 root root 7 Sep 1 02:24 root -> ../dm-0 lrwxrwxrwx 1 root root 7 Sep 1 02:25 swap -> ../dm-1 lrwxrwxrwx 1 root root 7 Sep 1 02:25 temp -> ../dm-2 We have applied the latest updates from the pve-no-subscription list proxmox-ve 4.2-60 Frustratingly if we look in the web panel under local-lvm we can see the Disk Images..... but just cannot access them ! We also tried to create a test disk on another VM and got this error lvcreate 'pve/vm-201-disk-2' error: Failed to activate thin pool pve/data. (500) That gave us a clue to look at lvdisplay and vgdisplay and we can see that both the main LVM and the disks show as 'Not Available' (see below) We presume there has been some corruption somewhere. From what we can see we could try something like these commands but don't want to make matters worse.... lvchange -a y /dev/pve vgscan --mknodes vgchange -a y Any help grateful received B.
