Read only File


Recommended Posts

For the last couple weeks about twice per week I have had to reboot my server because the /var/lib/docker/tmp/ folder shows as write only.  After a reboot it fixes the issue and i can then start using my docker containers again.  This has been annoying to say the least, but I have survived.  Today it happened again and I rebooted. Now the server is showing no docker containers and my cache drive is empty. Smart is still showing my cache drive as active and healthy. I don't know what happened or how to fix it. I was running around 25 containers some of them were DB's.  Is there a way to also recover?

No, your cache drive is unmountable. Totally different thing than an empty drive.

 

And since cache is corrupt and unmountable, all the things associated with dockers and VMs were recreated from scratch on disk10.

 

You will want to get rid of all that and see if you can get cache going again. Go to Settings - Docker and disable then delete docker.img. Do the same for Settings - VM Manager. Leave them disabled until we see if cache can be recovered.

 

Go to Unraid command line and post output of this

lsblk

Doesn't look like you have CA Backup plugin installed, so I am assuming you don't have backups of appdata or libvirt.

Just wanted to confirm the partition for your cache, since this FAQ assumes sdX1 and that isn't what you have with that nvme:
