convert jfs to jfs2 (non-rootvg) 1

[spamly]

I'm looking for a way to convert several filesystems from jfs to jfs2. Are there any ways to automate this? This isn't the root volume group, so I'd imagine that this has gotta be fairly simple. I've got the application down and I was planning on creating new jfs2 filesystems and just copying the data over, but I just wanted to check to see if there is a better way. What do you think?

I didn't get any immediate posts, so I converted it my own way. Here are the rough steps that I used. I'm use mock filesystem names here.

-Create a temporary filesystem (/temp-spot)
smit fs
...
- Copy data from /jfs-filesystem to new filesystem
cd /jfs-filesystem; tar -cvpf - * | (cd /temp-spot; tar xvpf -)
- Umount /jfs-filesystem
cd /; umount /jfs-filesystem
- Remove /jfs-filesystem
smit fs
...
- Create jfs2 filesystem the same size using the same mount point
smit lv I like to give my logical volumes names other than the default
smit fs
...
- Mount up the new filesystem
mount /jfs2-filesystem
- Copy data back to new jfs2 filesystem
cd /temp-spot; tar -cvpf - * | (cd /jfs2-filesystem; tar xvpf -)
- Purge data from /temp-spot
rm -r /temp-spot/*

Seems to have worked well. I converted 10 jfs filesystems this way.

A backup and restore is a conversion?

I was hoping for a way to convert the filesystems on the fly, but it didn't work out that way. You are right though, this ended up being essentially just a backup and restore.

There is no 'conversion'. You must backup/restore.
