I'm doing a storage migration on my 2 OMV5 instances (VMs under Proxmox with pass-through disks) from various RAID flavors on several 2TB HDD to few unmirrored "big" SSD.
Here's the plan:
1.- Attached SSD to the VM
2.- Wipe the SSD
3.- Encrypt the SSD (this is an extra, I've successfully tested the config within a test instance with unlock using NFS located file key).
4.- Create a single filesystem on the SSD
5.- Stop all clients, and reboot OMV5 VM
6.- Copy using rsync CLI the content of share folders from different FS (RAIDs) to the new FS (SSD)
7.- Move the Shared Folders using the GUI
8.- Stop/Start services (CIFS/NFS/RSYNC) or reboot
9.- Restart clients
10.- Delete & umount old FS, delete/wipe old disks & detach HDD from the VM.
I've already tested steps #5 to #9 because I needed to free some SATA connection for the SSD on the host but if everything went smooth with CIFS it was not successful regarding NFS. The /export/share1name and /export/share2name were empty. No error message, nothing wrong but I ended deleting the NFS shares (GUI) and recreated them exactly the same to make them working again. /etc/exports was just fine, nfs-server service was not complaining, clients were able to mount the "empty-root-located-shares" ...
Any idea on what I missed ?
Thanks a lot in advance
