gvinum(8) worked perfectly, thank you!

After adding geom_vinum_load=YES to /boot/loader.conf and rebooting, I tried 
to see if I could find my old partitions:

# gvinum list
1 drive:
D samsung6_1            State: up       /dev/ad1s1      A: 575/6102 MB (9%)

1 volume:
V home2                 State: down     Plexes:       1 Size:       5527 MB

2 plexes:
P home2.p0            C State: down     Subdisks:     1 Size:       5527 MB
P home2.p1            C State: down     Subdisks:     0 Size:          0  B

2 subdisks:
S home2.p0.s0           State: stale    D: samsung6_1   Size:       5527 MB
S home2.p1.s0           State: stale    D: samsung6_2   Size:       5527 MB

Then I tried:

# gvinum start home2
1 drive:
D samsung6_1            State: up       /dev/ad1s1      A: 575/6102 MB (9%)

1 volume:
V home2                 State: up       Plexes:       1 Size:       5527 MB

2 plexes:
P home2.p0            C State: up       Subdisks:     1 Size:       5527 MB
P home2.p1            C State: down     Subdisks:     0 Size:          0  B

2 subdisks:
S home2.p0.s0           State: up       D: samsung6_1   Size:       5527 MB
S home2.p1.s0           State: stale    D: samsung6_2   Size:       5527 MB

Everything came up, except the plex home2.p1 - no surprise, since that drive 
is dead and isn't even hooked up to this machine.

Finally, I tried to mount the home2 volume:

# mount /dev/gvinum/home2 /mnt

All my old files were there.

Thank you again for your help.
