Help!
sysinstall doesn't see _any_ drives on my system, so I'm trying to
disklabel my 3ware RAID array by hand. But when I try any disklabel
operations, it says "Operation not permitted".
This is with 4.1-S as of yesterday afternoon.
Here is the pertinent info from dmesg:
twed0: <3ware RAID unit> on twe0
twed0: 117797MB (241248384 sectors)
twed1: <3ware RAID unit> on twe0
twed1: 39265MB (80416192 sectors)
Mounting root from ufs:/dev/ad0s1a
twed0 is the RAID array
twed1 is actually the hot spare
Here is some commands and their output:
# mount
/dev/ad0s1a on / (ufs, local)
/dev/ad0s1e on /usr (ufs, local, soft-updates)
procfs on /proc (procfs, local)
# dd if=3D/dev/zero of=3D/dev/twed0 bs=3D1k count=3D1
dd: /dev/twed0: Operation not permitted
# disklabel -Brw twed0 auto
disklabel: /dev/twed0c: Operation not permitted
# disklabel -e twed0
disklabel: /dev/twed0c: Operation not permitted
I've tried lots of different combinations of the disklabel command,
and they all result in Operation not permitted.
# fdisk twed0
******* Working on device /dev/twed0 *******
parameters extracted from in-core disklabel are:
cylinders=3D15017 heads=3D255 sectors/track=3D63 (16065 blks/cyl)
=46igures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=3D15017 heads=3D255 sectors/track=3D63 (16065 blks/cyl)
fdisk: invalid fdisk partition table found
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 63, size 241248042 (117796 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 1;
end: cyl 680/ sector 63/ head 254
If anyone knows what I'm doing wrong, or what's wrong with this setup,
I could _really_ use the help. I've been struggling with the 3ware
array for too long now.
