Vinum

[Evan Sayer]

I have a question about how vinum effects access to file systems.  When 
i have a vinum volume on a drive which contains the file system /usr, 
which is being mirrored to another volume on another drive, are the 
contents of  /usr encompassed in the volume (like a partition) or is 
the volume just a part of /usr.  Basically i want to have a RAID-1 
setup that mirrors the information on one drive to another.  If i do 
this will i be able to access all the files on the first hard drive as 
though it was just a regular partition.  If so how do i partition, is 
there something special i have to do at the partition editor when i 
install?  Do i need subdisks and plexes just to mirror the file 
systems' data?  Sorry if this is a bad question but the handbook has me 
a little confused.  Thanks a lot.
