After reverting from OpenZFS to ZFS, I was able to destroy two of the boot environments that previously (below, 1st May, OpenZFS) could not be destroyed. I'm left with at least one BE 'r360237c' that can not be destroyed. Is it ever normal to find a snapshot described as '-'? root_at_momh167-gjp4-8570p:~ # kldstat | grep zfs 2 1 0xffffffff82109000 3a8b40 zfs.ko root_at_momh167-gjp4-8570p:~ # date Sun May 3 05:59:06 BST 2020 root_at_momh167-gjp4-8570p:~ # beadm list -as BE/Dataset/Snapshot Active Mountpoint Space Created Waterfox copperbowl/ROOT/Waterfox - - 314.0M 2020-03-10 18:24 r360237c_at_2020-03-20-06:19:45 - - 1.0G 2020-03-20 06:19 r357746h copperbowl/ROOT/r357746h - - 3.4M 2020-04-08 09:28 r360237c_at_2020-04-09-17:59:32 - - 1.1G 2020-04-09 17:59 r360237c copperbowl/ROOT/r360237c_at_2020-03-20-06:19:45 - - 1.0G 2020-03-20 06:19 copperbowl/ROOT/r360237c_at_2020-04-09-17:59:32 - - 1.1G 2020-04-09 17:59 copperbowl/ROOT/r360237c_at_2020-04-29-13:24:52 - - 11.2M 2020-04-29 13:24 copperbowl/ROOT/r360237c - - 80.4G 2020-04-29 13:24 r360237e copperbowl/ROOT/r360237e_at_2020-05-01-17:58:33 - - 96.6M 2020-05-01 17:58 copperbowl/ROOT/r360237e NR / 1.3G 2020-05-01 17:58 r360237c_at_2020-04-29-13:24:52 - - 11.2M 2020-04-29 13:24 root_at_momh167-gjp4-8570p:~ # beadm destroy r360237c Are you sure you want to destroy 'r360237c'?
