Hi Folks,
today I did an update from 7.2-RELEASE-p4 to 8.0-RELEASE using
freebsd-update.
Everything went smooth, apart from the fact that I can't mount my second
disk.
It's all a bit puzzling...
Here are the facts:
[r...@talisker ~]# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/ad4s2b none swap sw O O
/dev/ad4s1a / ufs rw 1 1
/dev/ad4s2a /tmp ufs rw 2 2
/dev/ad4s2d /var ufs rw 2 2
/dev/ad4s2e /usr ufs rw 2 2
/dev/ad8s1a /BACKUP ufs rw 2 2
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
linproc /compat/linux/proc linprocfs rw 0 0
The offending entry which isn't mountable anymore is ad8s1.
[r...@talisker ~]# sysctl kern.disks
kern.disks: ad8 ad4
fdisk and bsdlabel are showing my s1a partition/slice:
[r...@talisker ~]# fdisk ad8
******* Working on device /dev/ad8 *******
parameters extracted from in-core disklabel are:
cylinders=775221 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=775221 heads=16 sectors/track=63 (1008 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 63, size 781422705 (381554 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 52/ head 15/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
[r...@talisker ~]# bsdlabel ad8
# /dev/ad8:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 781422752 16 unused 0 0
c: 781422768 0 unused 0 0 # "raw" part,
don't edit
but:
[r...@talisker ~]# mount /dev/ad8s1a /BACKUP/
mount: /dev/ad8s1a : No such file or directory
And in fact:
[r...@talisker ~]# ls -l /dev/ad8*
crw-r----- 1 root operator 0, 91 Dec 15 17:58 /dev/ad8
crw-r----- 1 root operator 0, 96 Dec 15 17:58 /dev/ad8a
Huu? What's going on here? Where is s1?
Never seen that before... (and I'm using FreeBSD since 4.0-RELEASE).
and this mount obviously won't work either:
[r...@talisker ~]# mount /dev/ad8a /BACKUP/
mount: /dev/ad8a : Invalid argument
Anybody any idea how to recover here?
The server is unluckily remote and in production. A downgrade back to
7.2 would be kinda difficult. I'd like to avoid that.
Ideas anyone?
Thanks in advance,
Marian
