I have been running benchmarks on VM instances and accidentaly fully used up the storage of an instance.
The VM stopped responding and stopped immediately, I have tried to delete it however I got the following output:
$ lxc delete vm-test
Error: Error deleting storage volume: Failed to run: zfs destroy -r temp/virtual-machines/vm-test.block: cannot destroy 'temp/virtual-machines/vm-test.block': dataset is busy
Following are the contents of /proc/*/mounts
$ grep temp/virtual-machines/vm-test /proc/*/mounts
/proc/3728966/mounts:temp/virtual-machines/vm-test / zfs rw,xattr,posixacl 0 0
/proc/3728992/mounts:temp/virtual-machines/vm-test / zfs rw,xattr,posixacl 0 0
And zfs list:
$ zfs list | grep temp/virtual-machines
temp/virtual-machines 45.9G 0B 24K none
temp/virtual-machines/vm-test 5.79M 0B 5.81M /var/snap/lxd/common/lxd/storage-pools/temp/virtual-machines/vm-test
temp/virtual-machines/vm-test.block 45.9G 0B 46.6G -
I have found similar posts however I could still not solve the issue with the information given.
Any tips are appreciated.
