No:

5 drives:
D raid5-00              State: up       Device /dev/da1s1e      Avail: 0/4133 MB (0%)
D raid5-01              State: up       Device /dev/da3s1e      Avail: 0/4133 MB (0%)
D raid5-02              State: up       Device /dev/da5s1e      Avail: 0/4133 MB (0%)
D raid5-03              State: up       Device /dev/da6s1e      Avail: 0/4133 MB (0%)
D raid5-04              State: up       Device /dev/da7s1e      Avail: 0/4133 MB (0%)

1 volumes:
V raid5                 State: up       Plexes:       1 Size:         16 GB

1 plexes:
P raid5.p0           R5 State: up       Subdisks:     5 Size:         16 GB

5 subdisks:
S raid5.p0.s0           State: up       PO:        0  B Size:       4133 MB
S raid5.p0.s1           State: up       PO:      768 kB Size:       4133 MB
S raid5.p0.s2           State: up       PO:     1536 kB Size:       4133 MB
S raid5.p0.s3           State: up       PO:     2304 kB Size:       4133 MB
S raid5.p0.s4           State: up       PO:     3072 kB Size:       4133 MB

 - But since my first attempt to initialize the plex crashed the
box while only da5se1 was missing, I did a "verify media" from
the SCSI ctrl. BIOS, and did find errors. They were all successfully
remapped, though.

Newly created plex, so that would be the currently installed version.

Yup.  I am unable to try without SU right now (well, I could, but if it
doesnt work, my foot will be blown of), but I'll try that later when I
get home.
