[linux-lvm] EXT2 to EXT3 LVM volume on Redhat

[Aslak Sommerfelt Skretting]

Hello.


I've been using LVM for almost a year now, and im extremely satisfied.

I use it on a Redhat 7.2 fileserver with the 2.4.18 kernel.

I've combined 6 ide drives into a logical volume /dev/storage/space with an
EXT2 filesystem on it, totalling around 650gb of storage.

What I am wondering is, would it be wise to convert this filesystem to EXT3?
Or are there risks involved when doing this?


As far as i can understand a simple:

tune2fs -j /dev/storage/space

would create a new journal file, and convert the filesystem to ext3. and a:

tune2fs -i 0 /dev/storage/space

would disable the fsck's that occur now and then (and takes an insane amount
of time on a 650gb filesystem), and are no longer necessary since the
filesystem is EXT3.

and then everything would be ok? or is there more that need to be done?


Is this a complicated process that i might just as well avoid in order not
to damage my data? Or is this pretty straightforward?
