Hi, I have a server on which I lost a thin volume and I cannot figure out how to recover it. After installing 4.4, I followed these directions to add the thin volume on which I restored several VMs. This morning I came in and the server stopped on a reboot -- power outage I'm thinking.
I've tried everthing I can find online: vgchange -a y pve; lvchange -a y pve -- this one gives me a device-mapper error for each image that exists on the thin volume that's missing.
Here's some stats of the machine:
then running this:
lvconvert --repair pve/vz
Using default stripesize 64.00 KiB.
Operation not permitted on thin LV pve/vz.
Operations permitted on a thin LV are:
--merge
Any suggestions? I have full backups only 1 day old, so I'm not worried about the data, but I'm worried why this happened. I don't want to have to deal with this again. too much down-time.
