Mounting OpenBSD partitions

[Senandung Mendonan]

Hi list,

I have a multiboot system which includes OpenBSD and FreeBSD. In FreeBSD,
how do I mount OpenBSD partitions? Below are the relevant details of my
system:-

1. In FreeBSD:-
---------------
(i) fdisk:-
Disk name:      ad0                         FDISK Partition Editor
DISK Geometry:  4864 cyls/255 heads/63 sectors = 78140160 sectors(38154MB)
Offset       Size(ST)        End     Name  PType       Desc  Subtype
Flags
         0         63         62        -     12     unused        0
        63      80262      80324    ad0s1      7        fat        6
     80325   10442250   10522574    ad0s2      4 OpenBSD FFS      166
  10522575   28820610   39343184    ad0s3      8    freebsd      165
  39343185   38796975   78140159    ad0s4      4 extended DOS, LBA 15

(ii) disklabel ad0s2:-
disklabel: /dev/ad0s2: no valid label found

(iii) disklabel ad0s3:-
# /dev/ad0s3:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:  1024000        0    4.2BSD     2048 16384 64008
  b:  1171456  1024000      swap
  c: 28820610        0    unused        0     0
  d: 12582912  2195456    4.2BSD     2048 16384 28552
  e: 14042242 14778368    4.2BSD     2048 16384 28552

(iv) fstab:-
/dev/ad0s3a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad0s3d on /usr (ufs, local, soft-updates)
/dev/ad0s3e on /var (ufs, local, soft-updates)

2. In OpenBSD:-
--------------
(i) fdisk:-
Disk: wd0       geometry: 4864/255/63 [78140160 Sectors]
Offset: 0       Signature: 0xAA55
         Starting       Ending       LBA Info:
 #: id    C   H  S -    C   H  S [       start:      size   ]
------------------------------------------------------------------------
 0: 06    0   1  1 -    4 254 63 [          63:       80262 ] DOS > 32MB
*1: A6    5   0  1 -  654 254 63 [       80325:    10442250 ] OpenBSD
 2: A5  655   0  1 - 2448 254 63 [    10522575:    28820610 ] FreeBSD
 3: 0F 2449   0  1 - 4863 254 63 [    39343185:    38796975 ] Extended LBA
<snipped>

(ii) disklabel wd0:-
16 partitions:
#    size    offset  fstype  [fsize bsize   cpg]
a:   614187  80325   4.2BSD  2048 16384   328   # (Cyl.   79*- 688)
b:  1125936  694512    swap                     # (Cyl.  689 - 1805)
c: 78140160       0  unused     0     0         # (Cyl.    0 - 77519)
d:  6291936  1820448 4.2BSD  2048 16384   328   # (Cyl. 1806 - 8047)
e:  2410191  8112384 4.2BSD  2048 16384   328   # (Cyl. 8048 - 10439*)
i:    80262       63  MSDOS                     # (Cyl.    0*- 79*)
j: 28820610 10522575 unknown                    # (Cyl. 10439*- 39030*)
k: 14378112 39343248 unknown                    # (Cyl. 39031 - 53294)

(iii) fstab:-
/dev/wd0a / ffs rw 1 1
/dev/wd0d /usr ffs rw,nodev 1 2
/dev/wd0e /var ffs rw,nodev,nosuid 1 2

One other thing, though not related to FreeBSD: I can't mount FreeBSD
partitions in OpenBSD as well. UFS2 related issue?

Thanks.
