Steve,
I have compiled the CVS kernel from xfs, and have tried my snapshot script on
it.
It has successfully done 20 iterations. (this is a first for me.)
Not only did it succeed at this, but the time to perform an iteration dropped
drastically from using my prior kernel.
i.e. It typically took a couple of minutes per iteration to take the
snapshot/mount it/unmount it/delete it. Now it is taking around 10 seconds.
I have changed the iteration counter to 10,000 and I'm going to let it run over
the long weekend.
Hopefully we will have a success with this pure xfs cvs kernel.
