Volume suddenly read-only
All of a sudden and out of nowhere, my volume has become read-only. The system does not show any errors and no disk malfunction. What the hell? I'm updating all my backups now, but what should I do ...
Did exactly that. Run all bakcup jobs and update my offsite backup as well. Rebooted and the message of read-only no longer appears. It took a long time to calculate usage and free space. The last thing I did before this issue was un-assign and delete an iSCSI LUN. It was about 1.5 TB of data. Could the suddent deletion of that much data cause a problem?
The sahres are up but most of the files seem to corrupted. Cannot open any single file. This is a tremendous screw up on the NAS side.

If your backup is complete, I suggest doing a factory default (I wouldn't trust the volume integrity given the history).
PDFs, images and video files are opening just fine. Office documents and spreadsheets are not. Noone can open them, but the backups seem to be just fine. I'm suspecting a really strange file system corruption here.
Also, the usage calculation does not seem to be correct. I should have 12 TB of usable space in RAID 5 (using five 3 TB drives), but this is what I'm seeing (see attached).
