Hey folks,
I seem to be having some checksum issues (already!).
Build:
Gigabyte MB (Sock 775)
Intel E8400 C2D @ 3.0Ghz
12GB RAM
I am currently running 3x 3TB seagate drives in RAIDZ1. I was told that RAIDZ2 was better for data integrity and that I should purchase 3 more drives and rebuild the pool as a 6x 3TB RAIDZ2 array. I bought the extra disks and started backing up data before rebuilding the array. When copying certain files (noted below) the whole server would freeze. I am not able to use the web UI or ping the box and must hard reset the machine. After a hard reset it will boot up fine and the pool is reported as healthy but there is a yellow alert light with the following message:
WARNING: The volume volume (ZFS) status is UNKNOWN: One or more devices has experienced an error resulting in data corruption. Applications may be affected.Restore the file in question if possible. Otherwise restore the entire pool from backup.
The results of zpool status -v are below (after running a scrub):
I am going to try copying the files again to see if I get another hang up. After that what should I do? These are brand new disks.. is it possible all three are bad? Fortunately most of the data is backed up and anything that isn't can be easily ripped again.
Thanks!

Unfortunately I got the same result. I am going to delete the offending files and perform another scrub.
