I have a zpool (SSDs) comprised of three drives. This pool was moved to a UBUNTU system from a retired FREENAS system, and there is no "valuable" or meaningful data on the drives. The list of filesystems in this pool is:
SSDs 102G 1.66T 102M /SSDs
SSDs/hs-b44gx 102G 1.75T 7.30G -
I would like to delete the SSDs/hs-b44gz FS but destroy is not allowed because it is apparently busy.
I do not remember creating this zfs, and have no idea what "type" it is. (I tried "set mountpoint=" so I could see its data, but got
cannot set property for 'SSDs/hs-b44gx': 'mountpoint' does not apply to datasets of this type
My search for help with this found articles like this one (https://www.truenas.com/community/threads/unable-to-delete-datasets-busy.108347/). In general, the solutions I've found involve either deleting snapshots or unmounting the ZFS. But in this case, there are no snapshots apparently, and as mentioneed, mount (unless I misunderstand) is not valid.
What can be done to "unbusy" this ZFS? I am fairly new to administration of ZFS - I fought it for years with FreeNAS... now I would like to work with it on Ubuntu. Clearly I could just wipe it out and create an lvol or somesuch. But zfs sounds like a better answer.
