(Catching up on old mail, sorry I didn't respond earlier.) I will keep my promise... I have it ported to the 2.6.32-stable and 2.6.33-stable branches at this point. I was going to try to get up-to-date with the newest kernels first, but am now setting my sights on getting just what I have so far published. I will send an announcement when it's available. > You'll still need additional userspace support the to actually driver > the migration.

As Christoph said, SGI offers DMF (Data Migration Facility), but it is a proprietary product. -Alex _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
