Reduce size of ext3 filesystem in lvm2 in fly

[PaveQ]

So, is it possible to reduce size of ext3 in fly? Man page of resize2fs doesn't have big warning about it...

Don't know. the resize_reiserfs man page states that growing can happen on-line (and I've tried that and it works), but shrinking can't.
Since the e2fs doesn't state anything, I'd be sceptical about it and try it first on a test-file-system...
