I'm trying to set up a raid on my machine. I've used the DOS utilities
to create a mirror'd pack, and initialize it. I can partition & disklabel
it, but can't create a filesystem. Can anyone point out where I've screwed
things up? Things to look for? Thanks!
Rob
Here's what I've done:
The mlx driver sees the drive and I can get the config info via mlxcontrol:
# mlxcontrol config mlx0
# Controller <INSERT DETAILS HERE>
#
# Physical devices connected:
# disk0001 (online)
# 'WDIGTL ' 'WDE18300 ULTRA2 ' '1.30' 17461MB fast wide sync
tag-enabled
# disk0002 (online)
# 'WDIGTL ' 'WDE18300 ULTRA2 ' '1.30' 17461MB fast wide sync
tag-enabled
# disk0003 (standby)
# 'QUANTUM ' 'QM318000TD-SW ' 'N491' 17366MB fast wide sync
tag-enabled
#
# System Drives defined:
drive00 RAID1 writeback
span0 0x00000000-0x0221a800 17461MB on disk0001 disk0002
I've created the slice and labelled it:
# disklabel -r /dev/mlxd0
# /dev/mlxd0c:
type: SCSI
disk: mlxd0s1
label:
flags:
bytes/sector: 512
sectors/track: 32
tracks/cylinder: 128
sectors/cylinder: 4096
cylinders: 8729
sectors/unit: 35758048
rpm: 7200
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 35758048 0 unused 0 0 # (Cyl. 0 -
8729*)
e: 819200 32 4.2BSD 1024 8192 16 # (Cyl. 0*-
200)
But, when I try to newfs it, I get the following to the screen:
# newfs /dev/mlxd0s1e
/dev/mlxd0s1e: 819200 sectors in 200 cylinders of 1 tracks, 4096 sectors
400.0MB in 13 cyl groups (16 c/g, 32.00MB/g, 7680 i/g)
super-block backups (for fsck -b #) at:
write error: 80
newfs: wtfs - writecombine: Input/output error
and the following to the console & log:
/kernel: mlxd0s1: type 0xa5, start 32, end = 35758079, size 35758048 : OK
/kernel: bus_dmamap_load: Too many segs! buf_len = 0x5a0
/kernel: mlx0: I/O error - attempt to write beyond end of drive
a dummy newfs (newfs -N) produces what I'd expect:
# newfs -N /dev/mlxd0s1e
/dev/mlxd0s1e: 819200 sectors in 200 cylinders of 1 tracks, 4096 sectors
400.0MB in 13 cyl groups (16 c/g, 32.00MB/g, 7680 i/g)

BTW, a verbose boot gets the following info from the mlx driver:
