I've been running FBSD on this home server for about 13 years. Finally 
after a power outage, it will no longer boot.

The main drives were two SCSI drives striped using gstripe.  I am fairly 
certain da0 is dead and the reason it won't boot.

I know there was a working IDE or IDE via firewire enclosure drive 
before the crash.  I had backups on that drive made from Bacula and I'm 
hoping to be able to recover them.

If I'm interpreting all of the below dmesg output correctly, I think I 
should have an ad1 drive that I can mount. I'm hoping someone can 
confirm or deny that and help me get it mounted if ada1 should be there.

My version of FBSD on the box was 6.4.  I am now booted from the 9.2 
Live CD.

I'm checking dmesg to see what devices are seen:

da0 at ahc0 bus 0 scbus2 target 0 lun 0
da0: <SEAGATE SX19171W 9D32> Fixed Direct Access SCSI-2 device

Thus if I'm reading this right, it's seeing two internal IDE drives, a 
CD drive, and two SCSI drives?

Although I'm booted from the CD drive, apparently it is having problems 
based upon many of these messages:

(cd0:ata1:0:0:0): READ(10). CDB: 28 00 00 04 2e 78 00 00 01 00
(cd0:ata1:0:0:0): CAM status: SCSI Status Error

(cd0:ata1:0:0:0): READ(10). CDB: 28 00 00 04 2e 78 00 00 01 00

Then lots of these messages which tells me ada0 drives is dead?

(ada0:ata0:0:0:0): READ_DMA. ACB: c8 00 80 00 00 40 00 00 00 00 10 00

(ada0:ata0:0:0:0): Retrying command

Then it looks like there is hope for the stripe:

GEOM_STRIPE: Device data created (id=2880277341).
GEOM_STRIPE: Disk da0s1d attached to data.
GEOM_STRIPE: Disk da1s1d attached to data.
GEOM_STRIPE: Device stripe/data activated.

But then no hope as this sequence repeats itself:

GEOM_STRIPE: Disk da0s1d removed from data.
GEOM_STRIPE: Device stripe/data deactivated.
GEOM_STRIPE: Disk da0s1d attached to data.
GEOM_STRIPE: Device stripe/data activated.
GEOM_STRIPE: Disk da0s1d removed from data.
GEOM_STRIPE: Device stripe/data deactivated

Then I load the sbp module to see if I have any drives in the firewire 
enclosure:

fwohci0: <VIA Fire II (VT6306)> port 0x1c00-0x1c7f mem 
0xfc104000-0xfc1047ff irq

I suspect this means no working drives were found in the firewire enclosure?

So I check /dev and see if it sees ad1:

root@:~ # ll /dev/ad*
lrwxr-xr-x  1 root  wheel        4 Nov  2 18:07 /dev/ad0@ -> ada0
lrwxr-xr-x  1 root  wheel        5 Nov  8 13:38 /dev/ad0d@ -> ada0d
lrwxr-xr-x  1 root  wheel        4 Nov  2 18:07 /dev/ad1@ -> ada1
crw-r-----  1 root  operator  0x59 Nov  8 13:36 /dev/ada0
crw-r-----  1 root  operator  0x75 Nov  8 13:37 /dev/ada0d
crw-r-----  1 root  operator  0x5b Nov  2 18:07 /dev/ada1
root@:~ #

So I created /mnt/data and tried to mount ada1:

root@:~ # mount /dev/ada1 /mnt/data
mount: /dev/ada1: Device not configured

So then I try:

root@:~ # bsdlabel /dev/ada1
bsdlabel: cannot get disk geometry: No such file or directory

So does this mean I really don't have an ada1 drive?  Or is there some 
step I'm missing to make it accessible.

I really appreciate you reading this far and any help you might give.

Cheers,

Drew
