It would indeed! How have I missed this command before?
# zpool history pool
History for 'pool':
2017-08-20.15:45:43 zpool create -m /pool pool raidz2 da2 da3 da4 da5
da6 da7 da8 da9 da10 raidz2 da11 da12 da13 da14 da15 da16 da17 da18 da19
2017-08-20.18:36:39 zfs create pool/lofar
2017-08-25.16:45:28 zfs create pool/norman
2018-02-05.11:00:00 zfs create pool/mcmath
2018-09-07.12:13:27 zfs set compression=on pool/norman
2018-09-07.12:15:06 zfs set compression=on pool/lofar
2018-09-07.12:15:27 zfs set compression=on pool/mcmath
2018-09-07.12:15:32 zfs set compression=on pool
2018-12-03.12:27:43 zfs create pool/crisp
2019-06-24.16:08:09 zfs set quota=56T pool/lofar
2019-10-31.16:22:13 zpool export pool
2019-10-31.17:37:48 zpool import -a
2019-10-31.17:40:46 zpool export pool
2019-10-31.17:41:21 zpool import -d /dev/label -a
(So I wasn't quite right in my guessed 'create' command, but not too far
off)
Best wishes (and thanks),
Norman
