Do you include start_vinum="YES" in your /etc/rc.conf ?  It is likely given
information about past working, but maybe it was lost/changed?

After a subdisk has crashed the data is still valid so a 'vinum start' should
bring the plex back online.  This will then give you full access to your 
filesystems.
At that point you should run fsck on the vinum volumes to ensure no errors.

Anytime you start in single user mode you will need to begin with a 
'vinum start' command at least to get vinum going unless you load vinum 
in /etc/loader.conf or something.

To help any further we would need some specific error details.
