RN314 - cannot delete file / folder - file system error?
Hello community Using windows explorer and linked to my NAS via a mapped drive, I tried to delete a folder that contained a large number of backup files. This seemed to have processed ok for mos...
Did you download the log zip file, and look in there for errors?
Generally a backup job failure wouldn't put the NAS into a read-only state. It sounds like something more serious went wrong with the file system (perhaps while the backup job was running). Rebooting when it goes read-only was a bit risky - there are cases where the volume isn't mountable at all when you do that.
You can send a PM to one of the mods ( JohnCM_S or Marc_V ), and ask them to analyze your log zip. Include a downloadable link to the zip in the private message. You send/receive PMs using the envelope icon in the upper right of the forum page.
If you use the NAS for primary storage, you should also make sure your backup is up to date, as you might need to destory the volume and recreate it from scratch.
Hi StephenB, thanks, I suspected I would have to recreate the volume from scratch. I was hoping for some miracle chkdsk function like in NTFS file sysyems. Fortunately I have readyDR snapshots as well as external HD backups so no data will be lost, but oh the agony of starting from scratch, all the settings, backup jobs, plex servers, etc. *sigh*. This happens about every 2 years with my setup. Its so frustrating.
If the problem is only in the specific subvolume, you could potentially delete the share, and recreate it.
Then perhaps try some of the options here to look for issues: https://btrfs.wiki.kernel.org/index.php/Btrfsck
just today a second share also started giving me "source does not exist" errors, so I've taken the plunge and busy reseting the unit to factory default (30.84% complete after 2 hours... sigh). Something in the file system went really bad, I wish I knew why but I suppose it's just one of those bugs. The last time I had to restore from scratch, my unit was new enough for some support, and together we traced the bug to snapshots that were getting to big because the OS was not purging properly. This bug they fixed in their next OS release. Anyway, chalk this solution up to "It looks really bad, you do have backups right? 'Cause you gonna have to rebuild the volume from sratch! "
Thans for your help Stephen
