Assistance with migrating from Proxmox 1.9 to 4.4

OK, put the missing line in the file and you're good to go. Make sure to put an empty line at the end (an emply standalone line is not necessary but easier to make sure).
 
You can read too, can't you? The following line is not present in the fstab:

/dev/pve/data /var/lib/vz ext4 defaults 0 1
 
well yes of course, but i was just curious, was doing "nano fstab" not the right procedure?
I dont know how to put it in the file
