Hello, I'm doing an stateful install right now, and I have some questions to those who use the stateful method. Since I'm already used to stateless provisioning I'm trying to adapt it's concepts to stateful.
So here we go:
1. Can I use syncfiles to issue "updatenode all -F" when needed?
The ideia is to have a custom file with the synclist and run a command
similar to: chdef -t osimage -o ol8.4.0-x86_64-install-compute
synclists="/install/custom/install/compute.synclist"
2. Otherpkgs works in stateful profile?
Can I add otherpkgdir and otherpkglist to -install images? It will
install the packages during the provision phase? There's any use case for it?
3. Where should I do the customization inside the image?
On stateless I just chroot after "genimage", do whatever I need to do,
change confs, enable/disable service, etc, and them "packimage". How can I
achieve something similar with stateful nodes?
4. Can I have multiple pkglist and otherpkglist files?
The ideia here is to keep the default ones from xCAT untouched and just
add additional ones separated by commas in osimage definition.
Thanks all.
PS: I did some reading before, but I was only able to find precise information,
I've only found for hierarchical clusters and specific cases like CUDA, and
finally I'm not sure which is "The Right Way (tm)" to achieve the functionality
mentioned.
