zfs problem ufter update to 6.3.5-2

1. State before update.

1 zfs pool with 8 folders, which is assigned as shared folders.

Some fore NFS, some for samba, tftp, etc.

So i had some tree like:

dir1<--- | pool

dir2<---|

dir3<---|

dir4<---|

All works.

After update to 6.3.5-2 omv mounts folders that used for NFS through fstab (pool/dir1, pool/dir2) into /export and other folders gone.

Just empty mountpoint /pool. So all stop working except NFS. If I unmount this items (nfs used for) and mount zfs pool by hand all dirs rising again

as written above before update.

Sure. This behavior present on all pve kernels 5.15, 5.19, 6.1, 6.2. And as i remember my omv install using pve kernel since 6.0 or 6.1 OMV (already forgot when i changed kernel stream). So anything yet to check?

Solved by next sequence:

1. Switch to old pve-5.15 kernel, reboot to 5.15.

2. Delete all dkms and non Proxmox kernels.

3. Install new proxmox kernel 6.x

4. Update OMV, reboot, import zpool, apply changes in config, reboot.

if no installed proxmox kernels exist in system:

1. Delete all dkms modules, install old pve-5.15 kernel, reboot to 5.15.

2. Reimport zpool, apply config changes.

3.....

4....

Kernel and zfs pugins have to be installed before if not present.
