Hmmmm... Not necessarily true. There isn't enough info to give a good
answer. If this is software raid, then probably not. If this is
hardware raid then maybe.
There's two parts to this:
1) can a device be added to the raid group and the raid group extended
across it.
a) for software raid, if you're using LVM (Logical Volume Manager)
then yes you can add a device, if not then no.
b) for hardware raid, depends on the manufacturer. My Mylex
Acceleraid allows additional devices added after the raid group
is built. Other Manuf. do also.
2) is there a way to extend the file system
a) there is a utility called ext2extend (I think that's the name)
that allows a file system to be expanded or contracted. Note that
it's beta (alpha?) but seems to work. See Freshmeat for the current
rev
1.06. I seem to remember another, but cann't remember the name
right now.
This may not do you any good in this instance, but you might consider some
of the possiblities these present in your future planning.
