Hi,
the raid info keeps disappearing!, and im not convinced it's
hardware. I've tried it on 2 different - but similar - boxes, after some
time, kernel reports something like:
Jul 2 10:18:35 cs7.cs.huji.ac.il /kernel: ad6: hard error writing fsbn 0 (ad6
bn 0; cn 0 tn 0 sn 0) trying PIO mode
Jul 2 10:18:35 cs7.cs.huji.ac.il /kernel: ad4: hard error writing fsbn 0 (ad4
bn 0; cn 0 tn 0 sn 0) trying PIO mode
Jul 2 10:18:35 cs7.cs.huji.ac.il /kernel: ad6: hard error writing fsbn 0 (ad6
bn 0; cn 0 tn 0 sn 0) status=51 error=10

Jul 2 10:18:35 cs7.cs.huji.ac.il /kernel: ar0: ERROR - array broken
from dmesg:
...
FreeBSD 4.10-STABLE #7: Fri Jul 2 09:57:10 IDT 2004
...
ar0: 381564MB <ATA RAID0 array> [48642/255/63] status: READY subdisks:

i've partitioned the disk so:
# size offset fstype [fsize bsize bps/cpg]
a: 1024000 0 4.2BSD 2048 16384 90 # (Cyl. 0 - 63*)
b: 8388608 1024000 swap # (Cyl. 63*- 585*)
c: 781433667 0 unused 0 0 # (Cyl. 0 - 48641*)
d: 1024000 9412608 4.2BSD 0 0 0 # (Cyl. 585*- 649*)
h: 770997059 10436608 4.2BSD 0 0 0 # (Cyl. 649*- 48641*)
the machine boots diskless, so just to check the disk i did a newfs -U to
/dev/ar0s1a,
then restored a root image unto it, no problems.
the h partition has a big postgres data base, starting postgres i get the
above error, notice that
the error is a bit suspicious, fsbn 0 ( ... bn 0; cn 0; tn 0; sn 0)
using the Fastrack/Promise Bios i reconfigure the Raid, and if tried the above
again with
the same results.
btw, on a different host, same motherboard, same type of disks, with a older
kernel,
it panics, but the disk error is the same, and the array info is lost.
Any more info/help needed to track this down?
thanks,
danny
