Ok so it should be increase the size of a logical volume rather than

system without loss of data?

The man page for resize2fs says it will resize both ext2 and ext3 systems
provided they are unmounted but doesn't say whether data could be
corrupted.
Has anyone tried resize2fs with ext3 fs and is it safe?
There is one way to be sure: try it. ;-)

A quick test using the VM seems to be Ok - have you (or anyone else) hit any
problems with this?

It's safe, especially if umounted. Online resizer for ext2/3 is flakey,
there are too many circumstances that will force you to fsck the
filesystem before proceeding, and even then it seems to have limitations
with regards to when an online resize can happen and the ammount
of resizing that can occur... and in my experience it takes too
long to execute.

I agree with houghi though... give it a try and see if it fits your
needs. We looked at switching to ext3 with our large scale sans...
we ended up sticking with reiserfs.
