August 22, 20232 yr Woke up this morning and all of my VMs were paused. I forced stopped them and tried to restart them but it said there was no space available. They run off my cache which is a BTRFS pool of two SSDs. The pool has free space, only 391GB used out of 500. I tried running a balance on the pool but it said it wasn't required. Rebooted the server and now my VMs don't even show up in the list nor do my dockers which also ran off the cache. I can still connect to the cache via SMB share and all of the files are there and there does not seem to be any issue accessing or opening them. It does not look like there is any corruption of the data. Any idea what is going on? Diagnostics attached. tower-diagnostics-20230822-0813.zip

August 22, 20232 yr Author Thank you, I freed up some space and re-balanced the pool and after a reboot all is good. Much appreciated!
