November 15, 20187 yr Since upgradeing to 6.5.4 last week my machine has become unstable, first thing noticed was that dockers become unavailable, then the web interface. Hard reset then started a parity check and it froze the web interface again but could get to the shares via another machine so updated to 6.5.5. This time parity completed but soon after the dockers become unresponsive again. I've rebooted and the dockers remain unavailable with "docker service was unable to start" and when I try to start a VM i get Quote Execution error internal error: process exited while connecting to monitor: 2018-11-15T21:53:40.373025Z qemu-system-x86_64: -drive file=/mnt/cache/domains/Win7 Media Machine/vdisk1.img,format=raw,if=none,id=drive-virtio-disk2,cache=writeback: Could not open '/mnt/cache/domains/Win7 Media Machine/vdisk1.img': Read-only file system I'm guessing some folder permissions have got messed up somewhere and causing both issues?

November 15, 20187 yr Author Fix common problems has just notified me of "unable to write to cache". It's not full by the way.

This has been suggested in other similar cases by the disk/filesystem experts in the forum.
