I don't use swap over NFS, the machines that do have hard drives installed use them for local swap and cachefilesd (which is amazingly performant) In the past when I've tried to use an initramfs, it's lead to boot hangs that I haven't quite figured out the root cause for, I was trying to use genkernel to build them, maybe I'll give dracut a shot and see if that fixes the problem, you could very well be on to something. I believe "suspend to ram" might switch off the network (and kill a NFS connection in the process). This might be the cause of the issue. Do the nodes have enough memory to load the filesystem into RAM and run from there? (Like sysresccd can do) If yes, that might allow this to work. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity. Probably not enough ram, the lowest machine has 4 gigs, as an update I installed and tried out dracut, that didn't make any difference but each system booted fine an initrd which is a change for sure. If I manually suspend for up to say 10 seconds, they resume just fine. I like the idea S2ram killing the network as the cause, I thought enabling wake on lan would keep it from being switched off, I'll see if I can research the suspending/resuming routines and blacklist or whatever to keep it running, thanks for the tip :)
