In terms of migrations, it is still not documennted/limited. There's no mechanism to port a deployment image. I actually did a short proof of concept for booting xcat stateless images, it could be revisited. I suspect the security features would be omitted from xcat images, and may not support all the addressing modes, but would have to flesh it out.
For shifting a node over from one to the other for a reinstall, the biggest thing is to tell xCAT to 'let go' of the system for known systems (e.g. a mac.mac ending with '!*NOIP*''). For getting an xCAT node equipped with confluent ssh keys and confluent api token, I have done this but haven't wrapped that up in a nice procedure. It wasn't difficult, but would have to refresh my memory. Roughly it was putting the 'functions' and 'apiclient' on the node and running a short script. ________________________________ From: Vinícius Ferrão via xCAT-user <xcat-user@lists.sourceforge.net> Sent: Wednesday, January 5, 2022 10:22 PM To: xCAT Users Mailing list <xcat-user@lists.sourceforge.net> Cc: Vinícius Ferrão <fer...@versatushpc.com.br> Subject: [External] Re: [xcat-user] Confluent 3.3 is released, new stateless implementation Jarrod, this seems to bridge the gap between xCAT and Confluent. Stateless is a long missing feature on Confluent. I'll definitely give it a try when I have some spare time. Is there any hot migrations available (without reinstalling the entire cluster)? Thanks.

The big new thing is a new stateless implementation. Of some relevance to recent discussions on this list, there’s no ‘geninitrd’, instead the natural Dracut in the image builds the initramfs, making for easier customization, or at least customization that’s the same for diskless as it would be for diskful. _______________________________________________ xCAT-user mailing list xCAT-user@lists.sourceforge.net<mailto:xCAT-user@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/xcat-user<https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Fxcat-user&data=04%7C01%7Cjjohnson2%40lenovo.com%7Cdccfa52e449b4f2c9a3f08d9d0d10232%7C5c7d0b28bdf8410caa934df372b16203%7C1%7C0%7C637770418384024421%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=RaYGPYW%2BPJrCTLRVJoD0YFarwPmXNK%2FdLIu%2Fb8bAI5w%3D&reserved=0>
