Hi Sri,

with the statement "that you can't use all logical
volumes at the same time" I meant that one have to remember he/she has only 4 
"real" drives in the box and -
one is always free for faster mounts (I noticed that after the 4th drive is 
occupied,
one of the others is emptied. Always and immediately). This means that I have a 
maximum
of 3 disks working at a time. When I tried to access more than 3 mvs volumes 
concurrently, I had lots
of changing activity.

Regards
Roger
