I made a bad judgment and now my raidz pool is corrupted. I have a raidz pool running on Opensolaris b85. I wanted to try out freenas 0.7 and tried to add my pool to freenas. After adding the zfs disk, vdev and pool. I decided to back out and went back to opensolaris. Now my raidz pool will not mount and got the following errors. Hope someone expert can help me recover from this error. root@cempedak:/dev/rdsk# zpool status pool: syspool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM syspool ONLINE 0 0
