@cbits68 Hello again.
I can chip in on this bit:
Yes, we have seen this occur from time to time. And the hint is the following:
docker: Error response from daemon: stat /mnt2/ROCK-ONS/btrfs/subvolumes/bf85d96eb6bc3f36e633530611881ca3a8ee8da7bd107aa78341b4b3ae80a7ec: no such file or directory.'
It’s as if docker doesn’t recognise it’s own reports of the subvol it’s reporting. We haven’t tracked it down yet but we have seen this. And as you have found out, a new rock-ons-root kicks things off nicely again. As we have yet to established a reproducer we don’t have much to put in a GitHub issue for this one unfortunately. Well done on finding the work around. I’ve seen this myself but only after source re-installs over existing prior Rockstor docker configs that are still running.
Hope that helps,
