From: Mark Jacobs on 28 Mar 2010 18:23
I'm running snv_118 without any problems with my hardware but every
later release that I've tried gives me an error on the last drive of my
raidz2 pool. I just tried the latest snv_134 snapshot and once again my
pool came up in degraded mode.

Earlier attempts to run later snapshots gave me checksum errors, so
before ungrading today I ran a zpool scrub which reported no errors in
the pool. Under snv_134 its a different error, but the same end result.
When I go back to snv_118 the pool comes up fine.

Any ideas?
