I had a VM using RAW storage format on a ZFS storage object. I needed to delete the RAW hard drive files but couldn’t find them and the “remove” button was greyed out. One post mentioned using “qm rescan” which then allowed the poster to use the remove button but that didn’t work for me. After some research I found out that virtual drives on ZFS storage aren’t actually files but are “ZVOL”s. After a bit more research I came across the solution below to remove these drives manually.
rpool 209G 16.2G 96K /rpool
rpool/ROOT 13.8G 16.2G 96K /rpool/ROOT
rpool/ROOT/pve-1 13.8G 16.2G 13.8G /
rpool/subvol-102-disk-1 264M 7.74G 264M /rpool/subvol-102-disk-1
rpool/swap 15.9G 32.1G 37.7M -
rpool/vm-100-disk-1 51.6G 65.6G 2.11G -
rpool/vm-100-disk-2 51.6G 67.7G 64K -
rpool/vm-100-disk-3 58.4G 45.3G 28.6G -
rpool/vm-100-state-beforeInstallofDCcomponents 17.0G 31.9G 1.30G -
zfs destroy -f rpool/vm-100-disk-2
Next, I had initiated a “move” of the storage drive to an NFS share but it was taking forever. Proxmox, for whatever reason, lacks a “cancel” button for running tasks. After a bit of digging I found out I could kill the PID. Here is how that worked.
root 3828 0.0 0.5 347148 91928 ? Ds 14:53 0:00 task UPID:pm03:00000EF4:0001A237:56FC20BA:qmmove:100:root@pam:
root 4805 0.0 0.0 12728 1692 pts/0 S+ 15:07 0:00 grep qm
To kill the PID (3828) and stop the task I simply:
Probably not the cleanest things to do but it all worked…
