ok for casual usage and not too big a fs, but when it tends to grow ext3
has a lot of problems.

I am not talking of the jfs they have out, Enterprise storage manager is
built on lvm and jfs from AIX.. this has not yet been released into OSS,
but will be.

If You have tens or hundreds of servers already with volume manager and
Vxfs, the ability to have low cost servers on low cost hardware have the
same ... this will let it have momentum in the corporate world.

This is why I am so involved in using XFS ....
