SystemImager has a bit torrent mode available (see chapter 4
http://www.systemimager.org/documentation/systemimager-manual-4.1.6.pdf).
I've never used it with xCAT, but if they can be used together, that could
speed up parallel installs.
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.
Cheers,
Yuriy
