Should be. Raspberry Pis for example work that way.

If I were in your shoes, I would just run the regular detection process, let it create everything, and move the stuff over to the HDD, and let it boot from the HDD instead of PXE. Might even work without a lot of manual configuration.

would a disked md take some stress off the core? my core heats up during diskless boot?

How many MDs do you have that you start in parallel that your core heats up during serving of some files?

6 mds on core .. soon as one boots up the core starts to heat up but goes back down soon as boot is completed..

Check what is causing this. Use top, to see if something unusual is taking up the CPU, use dmesg to see if there are any errors being reported. All the MD is doing is requesting files, if that is causing issues, I am fairly certain that you have deeper issues.

my core didn't like 4.4 kernel that was causing it to heat up. when I went back to 3.13 it went back to normal temp

Nice to see you found out what's wrong. I am sure there are some settings for the 4.4 that will fix the heat issues as well, but if the 3.x is working, why not keep it
