I have a system running in a VM with a root pool. The root pool
occasionally shows a fairly stern warning. This warning comes with no check
sum errors.
bash-3.00# zpool status -vx
pool: rpool
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
see: http://www.sun.com/msg/ZFS-8000-8A
scrub: scrub in progress for 0h1m, 7.03% done, 0h13m to go
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
mirror ONLINE 0 0 0
c0d0s0 ONLINE 0 0 0
c0d1 ONLINE 0 0 0
errors: Permanent errors have been detected in the following files:
//dev/dsk
My question is can i safely ignore the warning if there is no check sum
error ?
Thanks
-Scot

You will need to detach the c0d1 side, change the EFI label to an SMI label, and reattach. The proper procedure for configuring bootable mirrors is in the ZFS Administration Guide. http://www.opensolaris.org/os/community/zfs/docs/zfsadmin.pdf -- richard> > errors: Permanent errors have been detected in the following files: > > //dev/dsk > > > My question is can i safely ignore the warning if there is no check > sum error ? > > Thanks > > > -Scot > > ------------------------------------------------------------------------ > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss >
