Joining the cluster, lvm-thin is lost

[tdyun]

I just joined a cluster server and something bad happened. The lvm-thin storage on the node is missing and I can't see any information in the web interface. I looked up a lot of cases and re-added the storage---lvmthin in the data center, but it didn't work, it's still missing. How can I get this thinpool back? It's in production and has VMs running. Sorry I'm new to this

Also see the part of the manual that mentions to only join EMPTY nodes:

All existing configuration in /etc/pve is overwritten when joining a cluster. In particular, a joining node cannot hold any guests, since guest IDs could otherwise conflict, and the node will inherit the cluster’s storage configuration. To join a node with existing guest, as a workaround, you can create a backup of each guest (using vzdump) and restore it under a different ID after joining. If the node’s storage layout differs, you will need to re-add the node’s storages, and adapt each storage’s node restriction to reflect on which nodes the storage is actually available.
