The lvextend is almost always safe, extending a mounted
file system can cause real pain if it glitches at all.
There are just too many ways for the system to get fried
if it croaks while someone is both writing a file and the
system is being updated and neither reiser nor ext3 nor
xfs nor lvm at this point seem solid enough to recover
gracefully from heavy duty failures at that point (at
least from what I've seen going by on the mailing lists).
