This seems to have been discussed quite a bit already, but we also moved our fileservers from inode to namei on ZFS in Solaris. Fortunately, this was part of a hardware upgrade, so all I had to do was set up the new file servers using ZFS, and use vos move to move over the volumes. Once it was do

At my last job, we had switched to using ZFS exclusively for our AFS servers, and had great luck with it. Look back in the archives of this list for discussion of it, and check out one of my ex-coworker's presentations from the 2007 AFS workshop on just that subject: http://elektronkind.o
