Hello zfs-discuss,
I''ve got many ydisks in a JBOD (>100) and while doing tests there
are lot of destroyed pools. Then some disks are re-used to be part
of new pools. Now if I do zpool import -D I can see lot of destroyed
pool in a state that I can''t import them anyway (like only two disks
left from a previously much larger raid-z group, etc.). It''s getting
messy.
It would be nice to have an command to ''clear'' such disks -
remove
ZFS signatures so nothing will show up for those disks.
What do you think?

Hi Robert, Maybe this RFE would contribute to alleviate your problem: 6417135 need generic way to dissociate disk or slice from it''s filesystem http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6417135 -r Robert Milkowski writes: > Hello zfs-discuss, > > I''ve got many ydisks in a JBOD (>100) and while doing tests there > are lot of destroyed pools.

Yeah, something like this.
However format(1M) isn''t ideal choice.
In my case with many disks it still would be quicker to use dd but I
do not like it. Something like zpool purge -D old_destroyed_pool would
be nicer.
