I do indeed have a pool of the same name; I can rename it of course but then scripts have to be changed. What I'm trying to do is get rid of the old entry because it is no longer relevant and causes a collision; I can get around the collision by using the UID of the pool on the mount when done manually, but that particular pool's devices are never coming back and every time an import is run the console complains about the missing device entries that cannot be probed. This is development box and thus I CAN wipe it to get rid of this, but if it happens on a production machine I'd like to know how to clear the problem. I understand that by doing so I irretrievably destroy the ability to get to the pool in the future but in this particular case the disks in question have been hard-overwritten with other data so that's already a fact irrespective of what the system thinks. -- Karl On 8/4/2013 12:27 PM, Steven Hartland wrote: > Might sound silly but what are you actually trying to achieve? > > Are you trying to create a new pool of the same name? > > Does ZFS still think it has the pool loaded via zpool status > and your trying to clear that? > > .... > > Regards > Steve > > ----- Original Message ----- From: "Karl Denninger" <karl@denninger.net> > To: <freebsd-fs@freebsd.org> > Sent: Sunday, August 04, 2013 6:19 PM > Subject: How do I clear this problem? :-) > > >> Development system here where I've been screwing around with ZFS and >> ZPOOL. >> >> I have a deprecated mirror that cannot be imported (the disks used for >> it were wiped and re-used); however, an attempt to destroy the pool >> fails because it's not mounted, and I can't find a command to clear the >> cache data that ZPOOL is using to find it. >> >> [root@dbms2 /]# zpool import >> pool: zstore >> id: 4828844235736846012 >> state: UNAVAIL >> status: One or more devices are missing from the system. >> action: The pool cannot be imported.
