Hi, I am installing 4.1.1 on the second partition of a two partition
IDE disk, both of which are FreeBSD. After "Commit", the installation
program says "can't find the root partition /".
I am running 3.3 at the moment on the second partition. The first one
is just a regular FreeBSD FS created by newfs after installing
3.3.
Here is the output of fdisk wd0:
******* Working on device /dev/rwd0 *******
The data for partition 1 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 63, size 4192902 (2047 Meg), flag 0
beg: cyl 0/ sector 1/ head 1;
end: cyl 260/ sector 63/ head 254
The data for partition 2 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 4192965, size 4225095 (2063 Meg), flag 80 (active)
beg: cyl 261/ sector 1/ head 0;
end: cyl 523/ sector 63/ head 254
Here are the disk labels:
/dev/rwd0s1c:
# size offset fstype [fsize bsize bps/cpg]
c: 4192902 0 unused 0 0 # (Cyl. 0 - 260*)
e: 4192902 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 260*)
# /dev/rwd0s2c:
# size offset fstype [fsize bsize bps/cpg]
a: 131072 0 4.2BSD 0 0 0 # (Cyl. 0 - 8*)
b: 1048576 131072 swap # (Cyl. 8*- 73*)
c: 4225095 0 unused 0 0 # (Cyl. 0 - 262)
e: 3045447 1179648 4.2BSD 0 0 0 # (Cyl. 73*- 262*)
When installing 4.1.1, all of the following trials was unsuccessful:
1. specify mount points for / /usr on ad0s2a and ad0s2e and toggle
newfs flags
2. remove all partitions on ad0s2 and use default allocation for /
/usr /var and swap.
3 manually recreate all partitions on ad0s2.
The first two approaches got me the "cant find root partition /" error
at "commit". The third method caused an error "cant create / in this
partition" when specifying mount point /.
I am guessing the installtation program gets confused by the first
FreeBSD partition ad0s1. It's very likely that if I remove that or
make it into a DOS partition things will work. But I would like to
keep it as it's a FS mounted by other NFS clients.
Can someone tell me how to get around that? Thanks very much.
