I’ve noticed a bug with latest and previous LXD versions that instances will get stuck after deletion is requested, the container will stick around in the RUNNING state.
$ lxc delete -f bc-crate-1d0aa532-add0-40b9-a7a8-b44689be5824
Error: Error deleting storage volume: Failed to run: zfs destroy -r master/containers/bc-crate-1d0aa532-add0-40b9-a7a8-b44689be5824: cannot destroy 'master/containers/bc-crate-1d0aa532-add0-40b9-a7a8-b44689be5824': dataset is busy
After running this command the container is stopped, but the problem still persists trying to delete. I’ve had to use the advice at https://github.com/openzfs/zfs/issues/1810 to kill processes, but this has to be done manually and isn’t ideal. Any ideas why this might be happening?
I’m using LXD 4.7/18137 on the snap package. Here is the containers configuration:
