Problem - multiple errors - Write error at byte

[Rivvern]

Please help me find the cause of my problems.

unraid-6.6.7

 

Some docker containers shuts down and doesnt start.

My VM doesnt start.

 

Getting this email notificitation:

fstrim: /var/lib/docker: FITRIM ioctl failed: Input/output error

 

Getting this Fix Common Problems notification:

Unable to write to cache - Drive mounted read-only or completely full.

Unable to write to Docker Image - Docker Image either full or corrupted.

/var/log is getting full (currently 78 % used) - Either your server has an extremely long uptime, or your syslog could be potentially being spammed with error messages. A reboot of your server will at least temporarily solve this problem, but ideally you should seek assistance in the forums and post your.... Yep, im here.

 

I can fix it shortly by doing a reboot. Error will reappear after a couple of hours/days.

Cache filesystem is corrupt. backup data, re-format and restore data, then recreate the docker image.

Cant i use the btrfs scrub? Maybe thats another function.

[JorgeB]

No, scrub is for data integrity, not filesystem repair, there's a btrfs fsck tool but it shouldn't be used for most cases, you can try it if there's no important data on cache, more info here (3rd option), best bet is to backup, re-format and restore.

Thank you for the quick response. Currently backing up the data.
