Thanks to the one respondent that wrote to me off the list with a patch that I
was able to apply to vinumio.c file. vinum now recognises my devices, great,
unfortunatly the patch I have is not the whole story.
After applying the patch
***./sys/dev/vinum/vinumio.c.orig Thu May 2 01:43:44 2002---
./sys/dev/vinum/vinumio.c Sat Oct 4 18:46:00 2003***************
*** 78,83 ****
--- 78,85 ----
devmajor = 116;
else if (bcmp(dname, "wd", 2) == 0) /* IDE disk */
devmajor = 3;
+ else if (bcmp(dname, "ar", 2) == 0) /* ATA RAID ckw */
+ devmajor = 157;
else if (bcmp(dname, "da", 2) == 0)
devmajor = 13;
else if (bcmp(dname, "vn", 2) == 0)
I can now add the volume to vinum and create sub-disks, plexes and volumes,
fantastic.
The configuration file I used is
drive BigDrive device /dev/ar0e
volume Home
plex org concat
sd len 20971520s drive BigDrive
volume Build
plex org concat
sd len 10485760s drive BigDrive
volume Shares
plex org concat
sd len 10485760s drive BigDrive
volume Books
plex org concat
sd len 10485760s drive BigDrive
volume MP3
plex org concat
sd len 251658240s drive BigDrive
volume Pictures
plex org concat
sd len 41943040s drive BigDrive
this then yields an out output of the vinum list command. Please excuse the
var , tmp and usr volumes shown, that's a separate vinum configuration that
mirrors my root file systems and works fine even between reboots....

This not looking so good. I cannot find a command to revive any of the
components I only get a response of the like
# vinum start Home
Can't start Pictures: Device busy (16)
or
# vinum init Home
Initializing volumes is not implemented yet
If I "vinum rm -rf <faulty volume name>" for all the now faulty components and
use my create script again, all my drives are magically OK, and I can fsck and
mount them just fine. Not that I anticipate rebooting this box much, beyond
when I patch it to the latest release, it will be a tad annoying to have to
rebuild my volume configuration on each reboot, and once I start extending
volumes it might get a bit on the stress full side trying to build everything
in the crorect order.
Has any one else any experience of using vinum on the ar0 device that
doesn't require rebuilding the configuration after each reboot.
Thanks for any help
David.
