ext2 -> ext3 on the fly?
From: Robert L. Harris

I have a number of servers which are currently mounting /usr as ext2. I
have a means of doing an tune2fs -j on all of them remotely en mass but
I'd rather not reboot them all to enable journaling on machines that are
up and not having issues. I've tried to do a:
mount -t ext3 -o remount /usr
as well as just a mount -o remount after changing the fstab.
on a test box but it just blows out a usage message. Is there a way to
do this remount without a complete reboot that'll be transparant to
users?
If not, is it dangerous to tune2fs the filesystems, change the fstab and
then leave the box up for 2-6 months and let them reboot through
atrrition, upgrades, etc?
Current kernel is 2.4.21-ac3, getting outages and upgrades is a rather
long process involving regression testing, etc.
