hey richard, so i just got a bunch of zfs checksum errors after replacing some mirrored disks on my desktop (u27). i originally blamed the new disks, until i saw this thread, at which point i started digging in bugster. i found the following related bugs (i'm not sure which one adam was refering to):
6847180 Status of newly replaced drive became faulted due to checksum errors after scrub in raidz1 pool http://bugs.opensolaris.org/view_bug.do?bug_id=6847180 6869090 on thumper with ZFS (snv_120) raidz causes checksum errors from all drives http://bugs.opensolaris.org/view_bug.do?bug_id=6869090 i think the issue i'm seeing may be 6847180. reading through the bug, i get the impression that it can affect disks in mirrors as well as raidz configurations. to complicate the situation, i just upgraded from snv_121 to snv_122. the initial checksum after resilvering errors i saw were on snv_121. i'm not seeing any new errors with snv_122. (of course i haven't tried a new resilvering operation since upgrading to snv_122, i'll probably do that tommorow.) i've zpool clear'ed the problem, did a scrub, and things look ok. i'm currently testing the pool by doing more scrubs + builds on it to see if i get any more errors. ed On Wed, Sep 02, 2009 at 09:19:03AM -0700, Richard Elling wrote: > > On Sep 2, 2009, at 2:38 AM, Daniel Carosone wrote: > >> Furthermore, this clarity needs to be posted somewhere much, much more >> visible than buried in some discussion thread. > > I've added a note in the ZFS Troubleshooting Guide wiki.
