How many?
Because Outlook is doing strange things with
long lines, i've attached the log as a separate
file.
BTW: I've found that the vinum 'out of the box' is configured
for 4 drives, 4 volumes, 8 plexes and 16 subdisks. If I want
more drives, volumes, plexes and subdisks, is it possible
to simply increase this values in vinumvar.h and recompile?
Does this have any affections in the speed of vinum?
Norbert
