Lost RAID after installation of PVE

[Indirectelex]

Each time I reinstall PVE I lost my ZFS RAIDZ, do you have a solution about that issue?

 

[apoc]

What do you mean by that?
Is it not showing up?
Is it destroyed?
Are you booting from it? Is it an additional pool?

When I reinstall PVE on the boot drive I lost all my configurations, this is quite normal, but I can't reload ZFS pool, I have to wipe my disks and then recreate ZFS pools. Is there a way to remount the storage?

First of all: go to the CLI and check if the pool is there via "zpool list".
if it is there, then the only thing to do is to register the pool to Proxmox again.
If it is not there you might need to import it. This might be of help:

BTW: You can backup your "storage.cfg" under /etc/pve and re-inject your configuration there after reinstall.

zpool import -f YourPoolName followed by adding a new ZFS storage (in webUI: Datacenter -> Storage -> Add -> ZFS) pointing to it usually does the job.
