But it seems ext3 has to be unmounted to increase and decrease in size right?
That would mean downtime for server.

ReiserFS seems to be only file system from

http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html

that can be extended and shrunk while the file systems are mounted and
are online without disrupting the Services that the Server offers.

I wonder how the shrinking takes place.
If there are possiblilites for loss of data and if it will give any
warning before it happens and so on?

Thankyou so much
