Hello guys,
I've completed the storage migration of one of my OMV5 instances. I moved from 4 HDDs (2x in R1, 2x basic) and 3 filesystems to a single encrypted SSD.
I moved one FS after the other with the following procedure:
1.- Rsync copy of shared folders from HDD to SSD (pass#1)
2.- Stop clients (NFS & CIFS)
3.- Rsync copy of shared folders from HDD to SSD (pass#2)
4.- Move shared folders to the new FS using the GUI
5.- Restart the clients and test
6.- Umount/Delete old FS & wipe old disks
Everything went fine (not really with NFS but with CIFS at least) for the first 2 FS. But same procedure with the last FS ended up with a missing FS in the GUI.
Everything but this missing FS works fine after a reboot but I'd like to git rid of it. I've tried to remove the <mntent> bloc (14 to 23) in config.xml which was not present it /etc/fstab but it was a mess after the reboot, it ended up with 2 missing FS including the valid one this time.
I can't find what is wrong, I guess something obvious is just in front of my eyes but I need someone to point me the issue 
# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
