Howdy!
I have 4 identical disks, labels etc are also identical.
It looks like vinum after reboot does not recognize drives
properly, as it did immedialtely after initial configuration.
One drive/subdisk in each plex isn't recognized, and the other one
is duplicated, which destroys the mirror.
I created 2 vinum volumes with
# vinum create -f /etc/vinum.raid1
and the following config file
drive data0 device /dev/da0d
drive data1 device /dev/da1d
drive data2 device /dev/da2d
drive data3 device /dev/da3d
volume mq0 setupstate
plex org concat
sd length 0 drive data0
plex org concat
sd length 0 drive data2
volume mq1 setupstate
plex org concat
sd length 0 drive data1
plex org concat
sd length 0 drive data3
after running
# vinum lv -r -v
I get (correctly)
Volume mq0: Size: 18341345792 bytes (17491 MB)

After rebooting the system and running
# vinum lv -r -v
I get the following incorrect configuration. Notice that
drives data0 and data1 are missing and drives data2 and data3 are
duplicated where data0 and data1 should be.
