Please send the output of "camcontrol devlist" and "zpool status" on
FreeBSD-8.1. Then export the pool in FreeBSD-8.1, boot FreeBSD-9 with
verbose booting and send the output of "camcontrol devlist", "zpool
import BACKUP" and the part of /var/log/messages that shows FreeeBSD
searching for the pool during the import.
Appended, you'll find some of the requested data. There is no valuable
dmesg/message output, due to the simple fact, that after yesterday's
"make world" and another import try the BACKUP00 pool was imported. The
only thing to report is, that while importing the BACKUP00 pool, which
is on devise ada3, I got an message on console like:
Nov 29 21:13:36 <0.2> thor kernel: ZFS WARNING: Unable to attach to ada1.
This strange message always came up when importing the BACKUP00 pool
(BACKUP is a typo, sorry for the inconvenience) and when it was about to
fail.
It might be useful to know what disk controller is being used.
=> 34 3907029101 ada3 GPT (1.8T)
34 4062 - free - (2.0M)
4096 3907025039 1 freebsd-zfs (1.8T)
It is not related to your problem, but how did that unused space wind up
before partition 1?
Well, my fault. I initiated the partitions with the "-b 4096" option set
for the first partition. It was so nice and at ease playing around with
gpart ...
And here comes the data requested:
#FreeBSD 8.2-PRE/amd64

(needed to swap 1st and 5th drive since FBSD 8 was installed with MBR
and no labels and needed device special file for mounting partitions
while on FreeBSD 9 I used the first time GPT partitioning scheme with
labeling for mounting via /etc/fstab)
#FreeBSD 8 zpool status:

vendor = 'Intel Corporation'

class = mass storage
subclass = SATA
cap 05[80] = MSI supports 16 messages enabled with 1 message
cap 01[70] = powerspec 3 supports D0 D3 current D0
cap 12[a8] = SATA Index-Data Pair
cap 09[b0] = vendor (length 6) Intel cap 2 version 0
In kernel config, I use AHCI driver modell, not the atapi one, but I
guess this is obvious due to 'adaXX' ...
And by the way, the 2 TB drive in question is sold as a 'PVR/VCR video
special device", I mistakenly ordered this one since it promissed low
power, high sustain-reliability (it is used for backups), but some web
sites claim that the controller of this specific, expensive 2 TB hdd
deals different with errornous blocks read or written out - I can not
verify this, since I have no technical paper nor do I understand much of
HDD electrical engineering ...

Oliver
