I have done such a thing. It's really not harder than moving to any
other FS. I messd up by making XFS a module, so when it came time to mount /,
it puked. it was a dumb mistake on my part, but I digress...
Here is the basic outline:
1: compile in XFS support. you may be able to do less, but I have these
XFS related options:
<*> Page Buffer support (EXPERIMENTAL) (required for XFS)
<*> SGI XFS filesystem support (EXPERIMENTAL)
[ ] Enable XFS DMAPI (incomplete)
[*] Enable XFS DEBUG mode (optional)
[*] Enable XFS Vnode Tracing (optional)
I believe all you *need* is Page Buffer and XFS support. someone
correct me...the key is to buld them _in_ the kernel, not modules, if you
intend on mounting / as xfs
2: compile the XFS userspace tools
3: make sure it all works on a spare partition
4: copy all your junk around and make the filesystems. or backup to
tape and restore onto XFS partitions. or whatever you want. I have the space so
I prefer playing 'musical partitions' with `cp -av`
5: I have a ext2 /boot, the rest is all XFS. note on the FAQ page it
says you can use a XFS /boot now, I have not tried that yet.
6: edit /etc/fstab to mount things 'xfs' where you need too.
7: run lilo
8: reboot
That's all there is. it's not complicated, just a little painstaking
and time consuming ("musical partitions" is responsible for that :) Another
thing to think about is if you have to have ext2 mounted, as I have /boot, you
can mount it as ro (readonly) and don't fsck on reboot. then you are safe using
ext2 on partitons that you only need RO access to. like maybe your MP3
collection.
/dev/hda1 /boot ext2 defaults,ro 0 0
does it for me. if you have to re-mount do this:
mount /boot -o rw,remount
that remounts the partition with rw access. Just a couple tips that
might help along the way, hope it helps :)
To everyone doing development on XFS: keep up the good work, things
work *great* (I'm already on your 2.4pre :)
