gvinum forgetting drives in 6.0R?

Thu Nov 10 20:42:18 PST 2005

I'm doing some testing in 6.0, and something strange is happening:

1) uname -a
FreeBSD  6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov  3 09:36:13 UTC 2005     
root at 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 plexoffset 
512s
 sd name v0.p0.s1 drive dr2 len 613376s driveoffset 265s plex v0.p0 plexoffset 
256s
 sd name v0.p0.s0 drive dr1 len 613376s driveoffset 265s plex v0.p0 plexoffset 
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?  
Also, everything is conveniently in the up state, but there is no /dev/gvinum 
directory.  

7) For kicks, add the following to /etc/rc.conf like I saw in an e-mail 
somewhere:

geom_vinum_load="YES"
start_cmd="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 
physical system I have.  I haven't tested other kinds of plexes yet, either.
