Description Pierre Ossman 2006-12-30 22:14:57 UTC 
A common scenario for smaller installations is that all servers reside on the
same UPS. This poses a problem when power comes back and all machines boot at
the same time. The machines depending on the NFS server will try a mount, get a
"connection refused" back, and give up.

What I'd like is for the machines to patiently wait for the NFS server to come
up, then proceed with the startup.

This could of course be extended to other network file systems, but NFS is my
particular itch.

Comment 2 Pierre Ossman 2006-12-30 22:16:22 UTC 
Ooops...

		if [ $[ $now - $start ] -gt 120 ]; then

should of course be

		if [ $[ $now - $start ] -gt $RETRANS ]; then
Comment 3 Bill Nottingham 2007-01-02 04:22:12 UTC 
Hm, might be simpler to wire it into netfs rather than a separate script.
Comment 4 Pierre Ossman 2007-01-02 05:50:02 UTC 
Perhaps. The advantage of a separate service is that you can easily turn the
function on and off. But a variable somewhere in sysconfig could also do that job.
Comment 5 Pierre Ossman 2007-03-09 20:45:07 UTC 
Any comments on this or something more I'd need to do? Would be nice to have
this in standard FC.
Comment 6 Bill Nottingham 2007-04-16 23:08:13 UTC 
I'd rather have a variable in sysconfig somewhere and do the wait in netfs itself.

Sorry for taking so long.

How about this patch?
Comment 8 Bill Nottingham 2007-05-08 21:11:30 UTC 
Aside from the logic seeming backwards (wait iff WAITFORNFS = "no"?), seems ok.
Will merge something along those lines post-F7.
Comment 9 Pierre Ossman 2007-05-09 05:40:09 UTC 
The backwards logic is actually intentional. The idea is that the function is on
by default, and you turn it off via sysconfig.
Comment 10 Pierre Ossman 2007-11-14 09:53:25 UTC 
Since we're now post-F8, I was hoping to see this feature. Any progress?
Comment 11 Pierre Ossman 2008-01-01 15:02:28 UTC 
re-ping
Comment 12 Bill Nottingham 2008-01-07 19:35:50 UTC 
Putting on tracker. Sorry about the delay.
Comment 13 Jon Stanley 2008-04-23 20:29:01 UTC 
Adding FutureFeature keyword to RFE's.
Comment 14 Lukáš Nykrýn 2013-03-14 14:25:54 UTC 
Initscripts no longer handle this -> close.
