Hi all, we want to use ZFS ( raidz2 without spares ) for store big amount of data on it. It's just a mirror so we don't give at damn if zfs is experimental ;-) I created some pool with the command: # zpool create x1 raidz2 aacd0 aacd1 aacd2 aacd3 aacd4 aacd5 It shows up correctly: # zpool status pool: x1 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM x1 ONLINE 0 0 0 raidz2 ONLINE 0 0 0 aacd0 ONLINE 0 0 0 aacd1 ONLINE 0 0 0 aacd2 ONLINE 0 0 0 aacd3 ONLINE 0 0 0 aacd4 ONLINE 0 0 0 aacd5 ONLINE 0 0 0 errors: No known data errors ]# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT x1 816G 230K 816G 0% ONLINE - All is fine till I reboot. The pool is just disappearing :-/ Here are the relevant config stuff: # grep "zfs" /etc/rc.conf zfs_enable="YES" # cat /boot/loader.conf geom_mirror_load="YES" zfs_load="YES" vm.kmem_size_max="512M" vm.kmem_size="512M" vfs.zfs.zil_disable=1 After reboot the module is loaded: # kldstat | grep zfs 2 1 0xffffffff80bc7000 f5a40 zfs.ko But the pool is loast: # zpool list no pools available Some more infos about the system: # uname -v FreeBSD 7.0-RELEASE #0: Sun Feb 24 10:35:36 UTC 2008 root@my.host:/usr/obj/usr/src/sys/GENERIC Some parts of dmesg: WARNING: ZFS is considered to be an experimental feature in FreeBSD.
