This worked, thank you.

Will try upgrading to 2.8.3

We recently moved from rinstall to system
imager to speed up imaging and
ensure consistency, but there are few issues.
1) Install is much faster for single node, but reimaging
100+ nodes at
the same time is very slow over 1gig network. Is it
possible to change
the IP of rsync server for images? I want to move to 10G
interface on
management server without changing dhcp interface. Also, is
it possible
to use 9000 MTU on genesis kernel. I added "option
interface-mtu 9000"
to dhcp.conf and this works once the machine is re-imaged,
but not
during imaging process.
[XQ]: compute nodes should use the ip address that got
from management node to download files from management node.
So compute nodes should use the dhcp interface to
communicate with management node, but you do not want to
change the dhcp interface. So currently, can not use the 10G
interface directly. Currently, the genesis can not configure
the mtu for interface.
2) clone fails because it tries partition the drives before
OS sees
them. It works when delay is added to *.master script. But
it has to be
done manually every time new image is created
#
# END disk enumeration
################################################################################
logmsg "Sleep to wait for disk to show up"
sleep 60
[XQ]: systemimager has a template file
"/etc/systemimager/autoinstallscript.template", all *.master
scripts were create based on this file. You can modify this
file,
and all new *.master scripts will be contains
all modifications.
3) fstab mounts use UUIDs. SystemImager is smart enough to
change UUID
for ext4 partition, but not for fat UEFI partition. This is
not a big
problem because we don't use UEFI-based tools on the host,
but would be
nice to have this fixed for aesthetic reasons.
[XQ]: Thanks for your suggestion, xCAT sysclone based on
sysmtemimager, we can report this problem to systemimager.
4) New boot entry is appended for every clone. It means that
frequently
imaged node may have dozens of "Linux" entries in boot
order.
[XQ]: What is you xCAT version. In xCAT 2.8.3, sysclone
will delete the old UEFI boot label before create new boot
label entry, the label name is "syscloneLinux" in
xCAT 2.8.3
5) We have a lot of different machines with
westmere/sandybridge/nahelem, connectx2/connectx3,
tesla/kepler gpus and
different amounts of RAM. Do we need images for every
combination? For
example, will the image built on sandybridge work on
westmere with no
issues? And is OFED compiled on machine with connect2x card
not
optimized for connect3x ?
[XQ]: We only test
sysclone on homogeneous
machines(same cpu, same disk). For heterogeneous machines, may meet errors.
Systemimager is based on filesystem, if all kinds of
machines have same filesystem, and same disks, same os. It
may work, but we did not test this scenario.

Yuriy
