I have a big problem. My NAS disks are full and i can’t access to my files. Can’t delete any files, can’t backup, can’t do anything. Every hdd status are failed.
I have important files on it, don’t want to format them.
I’ve recently had a similar experience on my linux file server. The partion wouldn’t mount because it was full (ext4). Others have confirmed similar problems, so I wonder if that might be happening here.
If that’s the case I’m not sure how you get around it. Maybe try mounting the hard disk drives on a linux PC to see what happens? I think others here have suggested similar rescue strategies/
If the partion is mounting, and if you can ssh into the sharespace, have a look for bloated log files. On linux based OSs they should be in /var/logs - generally it shoudl be reasonably safe to delete log files, which might be sufficient to mount the drives. Then reboot.
BTW, in the case of my file server the partition was badly corrupted (RAID5/ext4). I did in the end manage to rescue everything using the RAISE recovery tools.
