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. 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 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. 4) New boot entry is appended for every clone. It means that frequently imaged node may have dozens of "Linux" entries in boot order. 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 ?
