Hi,
After upgrading to b95 of OSOL/Indiana, and doing a ZFS upgrade to the newer
revision, all arrays I have using ZFS mirroring are displaying errors. This
started happening immediately after ZFS upgrades. Here is an example:
[EMAIL PROTECTED]:~$ zpool status
pool: rpool
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.
see: http://www.sun.com/msg/ZFS-8000-9P
scrub: scrub completed after 0h12m with 6 errors on Wed Aug 20 06:26:33
2008
config:

These are root pools, and this is the method in which they were created:
#1 - Partition first drive during installation.
#2 - Once OSOL was installed: prtvtoc /dev/rdsk/c6d0s0 | fmthard -s -
/dev/rdsk/c7d0s0
#3 - zpool attach rpool c6d0s0 c7d0s0
#4 - installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c6d0s0
#5 - installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c7d0s0
Anybody have any ideas? I'd blame failing hardware, but this started
happening on 3 different machines, immediately following the versioin
upgrade (it prompted me to upgrade my pools and I did.) I thought there
might be a problem, so I detached the secondary drives on all systems, and
performed the steps above listed again. Still having errors. Please let me
know what other data would be useful for you, and I'll provide it, I'm
interested in getting this resolved as soon as possible.
Cheers,
David
