Greetings.
I've recently had three hard drives fail in my server. One was the OS
disk, so I just reinstalled. The other two, however, were each one-half
of zpool mirrors. They are the problem disks.
Both have been replaced, but now I cannot seem to work with them. In
format -e, they are giving errors, specifically:
1. c3d1 <drive type unknown>
/pci@0,0/pci-ide@11/ide@0/cmdk@1,0
and,
7. c7d1 <drive type unknown>
/pci@0,0/pci-ide@14,1/ide@0/cmdk@1,0
There is also a third disk erroring out:
3. c5t9d1 <SS330055- 99JJXXK-0001 cyl 60797 alt 2 hd 255
sec 63>
/pci@0,0/pci1002,5a17@3/pci1000,9240@0/sd@9,1
I am suspecting c3d1 to be an old OS mirror, due to the low controller
number.
When I select 1 or 7, I get a Segmentation fault, and get booted out of
the format utility. (If I select 3, the format utility never comes back,
freezing.) A zpool status shows:
pool: Pool1
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not
support
the features. See zpool-features(5) for details.

errors: 737 data errors, use '-v' for a list
(Doing a zpool status -v freezes the terminal.)
The system has three disks connected to an LSI MegaRAID SAS 9240-8i
controller.
I am suspecting that disk 3 (c5t9d1) might be the detached mirror of
Pool1 ( c5t8d1), but being unable to work with it, I cannot verify this.
I have no idea on how to deal with the data mirror. Should I just detach
/dev/dsk/c11t8d1s0 ( 7152018192933189428) and hope that c6d0 will be
clean enough for a decent scrub? Or is /dev/dsk/c11t8d1s0 (
7152018192933189428) the disk with the less corrupted data? Not being
able to even get a listing (ls) of the data pool leaves me very hesitant.
Does anyone have any ideas on how to clean this up?
Thanks in advance,
Rainer
