exceeding disk space and read-only

[ploggy]

just want to check if these two are related.

 

My disk 4 mostly contains my download share and unfortunately left it full. it's currently 100% utilized (18MB free). At this point i am unable to delete or move any files using krusader or mc as im getting a write protected / read-only error on some files.

Please post the diagnostics.

According to the syslog in the diagnostics there is corruption on disk4 which could be why you are having problems.   I notice it in BTRFS format and that format seems prone to corruption when running out of space.

Looks like some lost writes, probably due to known firmware issues with some WD drives, to use them reliably with btrfs you should disable write cache.

Thanks for the replies. I have restarted the server and was able to gain write access back to the disk. 

 

I will continue to observe.

 

May i know exactly where in the syslog the corrupt was?

Just look in those diagnostics in /logs/syslog.txt and start reading it from the bottom, it will be obvious

Thanks. First time actually going to the diagnostic files.
