Hi All,
The drive my ftp server is storing it's files on is currently formatted
in ext2. How can I convert to ext3?

Hi
Obviously, the first thing is to enable ext3 support in that machine's
kernel. I recommend building ext3 into the kernel and ext2 as a
module, unless you're using red hat with there initrd-based booting
scheme. Then, assuming that machine has at least e2fsprogs 1.3, execute:
tune2fs -j partition
Note, do not use the mount point, but use the actual partition. If at all
possible, unmount the partition before doing this. If that is not
possible, at least mount the filesystem read-only to minimize possible
corruption. I personally haven't experienced corruption even when the
partition was mounted, but better to be safe. The chance of corruption is
quite small, as all it does is create the journal, it doesn't actually
convert anything, since it doesn't have to. Ext3 is simply ext2 with a
journal. Now, edit /etc/fstab and change the filesystem type of that
partition from ext2 to ext3. Reboot with the ext3 enabled kernel and
you're done.

Simple, go read the ext3 howto.

Alex,
An ext3 filesystem is simply an ext2 filesystem with a journal. Therefore, if you use tune2fs to add a journal to the filesystem, this will effectively convert the filesystem to ext3. All you have to do to do this is to issue this command as root.
tune2fs -j <device>
Replace <device> with the device the filesystem resides on. Make sure you unmount the filesystem before doing this. Backing it up is not necessary however, as this does not destroy any data on the filesystem.
Note that if this is an automatically mounted filesystem, you will need to change ext2 to ext3 in your fstab file in order to make use of the new journaling capabilities. If it is not, simply make sure that the filesystem is being mounted with type ext3 when you mount it.

Hi.
thanks for the info. since this is my root filesystem, should I boot
into single user mode to do the conversion?On Sat, Jul 12, 2003 at

As far as adding the journal, no need to boot to single user mode before issuing the tune2fs command. However, you will need to remount the file system with the new type. Just to be safe, I'd would recommend totally restarting the machine since this will ensure this works properly. Changing the FS on the root filesystem generally only works properly after a restart.
