I'm doing some testing in 6.0, and something strange is happening:
1) uname -a
=46reeBSD 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov 3 09:36:13 UTC 2005=
=20
root@x64.samsco.home:/usr/obj/usr/src/sys/GENERIC i386
2) I build a stripe set using 'gvinum create' and the following config:
drive dr3 device /dev/ad3s1
drive dr2 device /dev/ad2s1
drive dr1 device /dev/ad1s1
volume v0
plex name v0.p0 org striped 256s vol v0
sd name v0.p0.s2 drive dr3 len 613376s driveoffset 265s plex v0.p0 plexoff=
set=20
512s
sd name v0.p0.s1 drive dr2 len 613376s driveoffset 265s plex v0.p0 plexoff=
set=20
256s
sd name v0.p0.s0 drive dr1 len 613376s driveoffset 265s plex v0.p0 plexoff=
set=20
0s
3) After this is done, everything's okay, and 'gvinum l' looks like:
3 drives:
D dr1 State: up /dev/ad1s1 A: 0/299 MB (0%)
D dr2 State: up /dev/ad2s1 A: 0/299 MB (0%)
D dr3 State: up /dev/ad3s1 A: 0/299 MB (0%)
1 volume:
V v0 State: up Plexes: 1 Size: 898 MB
1 plex:
P v0.p0 S State: up Subdisks: 3 Size: 898 MB
3 subdisks:
S v0.p0.s0 State: up D: dr1 Size: 299 MB
S v0.p0.s1 State: up D: dr2 Size: 299 MB
S v0.p0.s2 State: up D: dr3 Size: 299 MB
4) gvinum saveconfig
5) Reboot
6) 'gvinum l' now looks like:
0 drives:
1 volume:
V v0 State: up Plexes: 0 Size: 0 B
1 plex:
P v0.p0 S State: up Subdisks: 0 Size: 0 B
3 subdisks:
S v0.p0.s0 State: up D: dr1 Size: 299 MB
S v0.p0.s1 State: up D: dr2 Size: 299 MB
S v0.p0.s2 State: up D: dr3 Size: 299 MB
Notice the lack of drives and the subsequent death of my plex and volume? =
=20
Also, everything is conveniently in the up state, but there is no /dev/gvin=
um=20
directory. =20
7) For kicks, add the following to /etc/rc.conf like I saw in an e-mail=20
somewhere:
geom_vinum_load=3D"YES"
start_cmd=3D"gvinum start"
8) Reboot
9) Things still look like 6) above.
Is this a bug or am I silly?
Caveat: This testing is being done in qemu, but the behavior matches a=20
physical system I have. I haven't tested other kinds of plexes yet, either.
