Hi,
next try.
Please forgive if gets too stupid :-)
# cat x
drive d1 device /dev/da1d
drive d2 device /dev/da2d
volume raid
plex org stripe 256k
sd length 50m drive d1
sd length 50m drive d2
(please note again the misspelling of striped)
# vinum create x
1: drive d1 device /dev/da1d
** 1 Can't initialize drive d1: Device not configured
2: drive d2 device /dev/da2d
** 2 Can't initialize drive d2: Device not configured
4: plex org stripe 256k
** 4 Invalid plex organization: Invalid argument
5: sd length 50m drive d1
** 5 Unnamed sd is not associated with a plex: Invalid argument
6: sd length 50m drive d2
** 6 Unnamed sd is not associated with a plex: Invalid argument
Configuration summary

V raid State: down Plexes: 0 Size: 0 B
(juppie no panic!)
(Ok, after repairing 'striped' in x)
# vinum create x
Configuration summary
Drives: 0 (4 configured)
Volumes: 2 (4 configured)
Plexes: 1 (8 configured)
Subdisks: 2 (16 configured)
V raid State: down Plexes: 1 Size: 100 MB
P raid.p0 S State: down Subdisks: 2 Size: 100 MB
S raid.p0.s0 State: stale PO: 0 B Size: 50 MB
S raid.p0.s1 State: stale PO: 256 kB Size: 50 MB
(Hmm, stale sigh. The vinum(8) GOTCHAS 2. is not explicit about my situation.
this time, no `vinum resetconfig`, so:)
# vinum detach raid.p0
# vinum detach raid.p0.s0
# vinum detach raid.p0.s1
(Maybe this was too stupid and I get a deserved:)
..panic..
