Pool Missing

samip · Jul 23, 2013

Hello all,

I have a problem that I cannot locate my ZFS pool. (It should be called Storage, but I don't know how to query all HDDs to search for it.)

HDDs:

My /etc/fstab is as follows:

Code:

# Device                Mountpoint      FStype  Options         Dump    Pass#
/dev/ad4s1b             none            swap    sw              0       0

So I'm trying to recover a ZFS pool from 9.1 FreeBSD.

My system now is:

Code:

FreeBSD domain name sencored 8.4-RELEASE FreeBSD 8.4-RELEASE #0 r251259: Mon Jun  3 01:14:28 UTC 2013     root@bake.isc.freebsd.org:/usr/obj/usr/src/sys/GENERIC  i386

So please give me advice.

First off, don't mount ZFS via fstab. That could easily create confusion when debugging something like this. Secondly, you may want to check the output of # zpool list and # zpool import. If that doesn't give any useful information, you may want to run a command like # gpart show -lp to get partition labels and # gpart show -p to get partition types. You may also want to run # gpart show -p | grep "freebsd-zfs" to only display ZFS partitions.

Thanks. The command zpool import did it for me.

Problem Solved. Moderators please mark this thread as solved.
