My problem is that I cannot create vinum objects on a Promise TX200 ATA raid
The system is Dual P450 PIII on a Asus motherboard with 512MB RAM, 2
9GB SCSI drives as my boot devices.
I have installed a Promise TX2000 ATA raid controller and attached 4 x 200GB
drives, that I have configured as a single 400GB Raid 0+1 on the controller
and the OS 'FreeBSD ball.lan.raffles-it.com 4.9-STABLE FreeBSD 4.9-STABLE#1:
Fri Dec 19 19:34:25 GMT 2003' sees the drives and I can create a standard UFS
partition and mount the drive. The output from dmesg showing the probed
ar0: 381469MB <ATA RAID0+1 array> [48630/255/63] status: READY subdisks:
0 READY ad0: 190782MB <WDC WD2000JB-32EVA0> [387621/16/63] at ata2-master

I can create between 7 and 32 partitions using this method, depending on how I
use fdisk and disklabel, but they are fairly inflexible in terms of resizing
the partitions and i would be almost impossible to grow a file system. So I
though it might be possible to create lots of small vinum sub-disks out of my
single disk and then build plexes and volumes as and when I require them and
when I want to resize a partition, add a new sub-disk/plex to the volume and
grow the file system in to the new space.
The disklabel that is currently installed on ar0 is
# disklabel -r ar0 /dev/ar0c:
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
# size offset fstype [fsize bsize bps/cpg]
c: 781240887 0 unused 0 0 # (Cyl. 0 - 48629*)
e: 781240887 0 vinum # (Cyl. 0 - 48629*)
The configuration file I used to define the drive was
drive bigdrive device /dev/ar0
drive bigdrive device /dev/ar0e
drive bigdrive device /dev/ar0s1e
and the response I got each time was
1: drive bigdrive device /dev/ar0e
** 1 Can't initialize drive bigdrive: Operation not supported by
device 0 drives:
between each invocation pf the create command I did a "resetconfig".
Thanks for any light you can shed on this.
