Hi!
I am a little bit confuse by the nodes used for others BSD partitions.
Let me clarify.
I have added a new bigger hard drive to my system :
Here is an excerpt from dmesg :
wdc0: unit 0 (wd0): <ST34312A>
wd0: 4111MB (8420832 sectors), 8354 cyls, 16 heads, 63 S/T, 512 B/S
wdc0: unit 1 (wd1): <QUANTUM FIREBALL CX10.2A>
wd1: 9787MB (20044080 sectors), 19885 cyls, 16 heads, 63 S/T, 512 B/S
wd1 is the new drive
and fdisk display :
bash-2.03# fdisk wd1
******* Working on device /dev/rwd1 *******
parameters extracted from in-core disklabel are:
cylinders=1247 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1247 heads=255 sectors/track=63 (16065 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 11,(DOS or Windows 95 with 32 bit FAT)
start 63, size 6008247 (2933 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 1;
end: cyl 373/ sector 63/ head 254
The data for partition 2 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 6008310, size 12016620 (5867 Meg), flag 0
beg: cyl 374/ sector 1/ head 0;
end: cyl 1023/ sector 63/ head 254
The data for partition 3 is:
sysid 131,(Linux filesystem)
start 18024930, size 2008125 (980 Meg), flag 0
beg: cyl 1023/ sector 63/ head 255;
end: cyl 1023/ sector 63/ head 254
The data for partition 4 is:
<UNUSED>
bash-2.03#
My current installation of FreeBSD (3.3) is on wd0. I want to access to
the new partitions on the wd1 drive.
I expected to see these others BSD partitions as
/dev/wd1s2x
whereas
bash-2.03# ls wd1*
wd1 wd1b wd1d wd1f wd1h wd1s1a wd1s1e wd1s2 wd1s4
wd1a wd1c wd1e wd1g wd1s1 wd1s1b wd1s1f wd1s3
bash-2.03#
bash-2.03# mount /dev/wd1s1a /mnt
mount: /dev/wd1s1a on /mnt: incorrect super block
bash-2.03# mount /dev/wd1a /mnt
bash-2.03# ls /mnt
..cshrc boot dist kernel.GENERIC opt stand var
..profile cdrom etc lkm proc sys
COPYRIGHT compat home mnt root tmp
bin dev kernel modules sbin usr
bash-2.03#
Why is it named wd1a ???
Is this a bug?
Thanks
Phil.
