Hi Jay,
Jay Anderson schrieb:> I have b105 running on a Sun Fire X4500, and I am constantly seeing
checksum errors reported by zpool status. The errors are showing up over time on
every disk in the pool. In normal operation there might be errors on two or
three disks each day, and sometimes there are enough errors so it reports
"too many errors," and the disk goes into a degraded state. I have had
to remove the spares from the pool because otherwise the spares get pulled into
the pool to replace the drives. There are no reported hardware problems with any
of the drives. I have run scrub multiple times, and this also generates checksum
errors. After the scrub completes the checksums continue to occur during normal
operation.

OpenSolaris builds I am running CIFS Server, and that''s the only
difference in server function from when Solaris 10u4 was installed on it.

We had something similar two or three disk slots which started to act
weird and failed quite often - usually starting with a high error rate.
After exchanging two hard drives, the Sun hotline initiated to exchange
the backplane - essentially the chassis was replaced.
Since then, we have not encountered anything like this anymore.
So it *might* be the backplane or a broken Marvell controller, but it''s
hard to judge.
