We, and I believe most sites, utilize some form of shared storage (NFS,
CIFS/Samba, or some parallel FS) for home directories which will remove
the need to do any kind of user data synchronization. Just make sure the
home directory is mounted in the same place on all machines in the

What we’ve usually done when we need these types of packages is to use
yumdownloader on the management node. We figure out all the packages we’ll
need, including dependencies, and with the proper repo configured on the

XCATBYPASS means you are not running with xcatd. If the problem is
running with xcatd, I would like to understand why. That would be a bug.

I've got a small test cluster with working stateless nodes. Recently I
tried to add 2 more nodes and I can't get them to deploy the same
stateless image. For some reason the tftp configuration files are
getting touched when I run nodeset, but not changed to point to the
correct boot images.
Regarding the MIC support in this latest release I want to first say
Thank You! We got a couple of nodes with MIC cards a couple of weeks ago
and I've been working on getting them build with our xCAT install. I was
able to get them working, but this will hopefully make it much easier to
