On Going Docker problems


Recommended Posts

HI Everyone. 

 

I'm asking for help again! 

 

All my docker apps disappeared after a power cut here last week. I followed Squids excellent advise to delete the corrupted Docker image and reinstall the apps. 

 

All worked fine for a week or so until all the docker apps stopped and would not restart. 

 

I deleted the docker image again and started reinstalling the apps but I now get an error when installing.

Oct 9 10:31:49 UnRaid emhttp: shcmd (345): /usr/sbin/hdparm -y /dev/sdg &> /dev/null

 

It states that my Cache disk is full but it is at approx 60% full. 

 

 

I get the attached error when trying to start Plex or open VPN from the docker.

Thank you.

Done, had to relocate 0 out of 58 chunks

What size is your cache disk? Not combined.

I see whats going on,

 

You're running RAID1 which is mirroring, your smallest disk is a 60GB disk and you've used 55.9GiB which is pretty much 60GB

 

not sure why 90GB is shown but I don't belive that is accurate, it should read 60GB

 

Paging @johnnie.black, he might have a solution to regain your cache. I don't use a cache pool (single 250Gb for me)

 

Edit: Johnnie beat me too it.
