[zfs-discuss] Strange errors in zpool scrub, Solaris 10u6 x86_64
I did a zpool scrub recently, and while it was running it reported errors and
woed
about restoring from backup. When the scrub is complete, it reports finishing
with
0 errors though. On the next scrub some other errors are reported in different
files.
"iostat -xne" does report a few errors (1 s/w on each of 2 mirrored
drives, and 2 h/w
errors on one of the drives).
Any ideas? Is it a cosmetic problem or a crawling-hiding bug in my hardware and
I should go about replacing something somewhere? I don''t see such
behavior on
any other servers around...
Thanks for ideas,
//Jim
