SSD for VMs Failed & was replaced how to best reconfigure and restore the VMs

[danleeper80]

Got a situation I have an existing PVE installation in which I experienced a failure of my NVMe SSD and lost the VMs. Thankfully I have backups and now have a replacement drive after waiting for months to have SanDisk replace it under warranty. Now I have my replacement drive I need to do a restore of the VMs however, the LVM PV & LV's were lost both Linux and PVE are still looking for the old drive. I know of one way to handle recovery which is just blow away, reinstall PVE and start over that way or can/should I delete and start over the LVM configuration. Pros/Cons? What is the best way to restore my VMs and have everything in a happy state in the end.

Thanks for the input in advance!

Check out the scripts, EDIT before running. If you name the storage the same way it's currently defined in Datacenter / Storage, shouldn't have to do much. Otherwise might have to delete the lvm-thin in the GUI and redefine it after recreating on-disk.

You could also format the disk as a single-disk ZFS pool and get away from lvm-thin.

Also check out the bkpcrit script, point it to external disk / NAS, run it nightly in cron
