Hi all!

I have my drbd disk on a logical volume that is running out of space. 

    device     /dev/drbd0;
    disk       /dev/vg01/lv01;

drbd0 is 400GB and about 80% full.

Is there any danger or issues of concern if I want to simply extend
logical volume lv01 and thus increase the size of device drbd0? Can this
be done "live," or is there a special procedure? Will this have any
implications for the ext3 filesystem mounted on drbd0?

Also, as a separate question, are there any performance or reliability
issues that I should know about that occur when drbd disks start filling
