We have two servers, both running NFS shares. A while ago we upgraded them from 12.04 => 14.04, and ever since a clean reboot from the command-line has become all but impossible (well, we run into a timeout of some sort, I guess, but the reboot cycle takes > 8 minutes, which is highly undesirable).

They used to reboot fine (time taken for hardware checks & BIOS <3 minutes), but these days rpcbind sits there for what feels like forever.

How do I make that long wait go away again?

  • If you can, get rid of all NFSv3 or older. – Michael Hampton Feb 06 '18 at 21:33
  • @MichaelHampton - you mean try to replace it w/ nfsv4? – tink Feb 06 '18 at 21:35
  • Yes, NFSv4 or later. v3 is a horrible nightmare, and v2 was even worse. NFSv4 is almost 20 years old now... – Michael Hampton Feb 06 '18 at 21:38
  • Well, there's that. But it was simple and quick to set-up. Will investigate. Do you know for sure that v4 would make that behaviour go away, or is that a general suggestion? ;} – tink Feb 06 '18 at 21:40
  • I can't say for sure, or I would have posted an answer. But it's something you really should do anyway. NFSv4 isn't harder to set up than v3; it's _easier_. And it actually works better than v3. They removed a lot of unnecessary complexity (like portmap, etc). – Michael Hampton Feb 06 '18 at 21:44
