[SOLVED] Netfs shutdown routine takes ages

.:B:. · 2010-08-11 00:34:49

I have been running Arch on my AppleTV for a while now, but after adopting netfs to automate NFS mounts at boot I am experiencing long hangs during the shutdown process. It will hang on the netfs service for about a minute (or even more) and then proceed to shut down cleanly. Since the network is brought down only at the end, it shouldn't be a network timeout problem.

This is my DAEMONS array:

DAEMONS=(syslog-ng @acpid network @dbus @crond @dropbear @alsa @cpufreq @ntpd nfs-common netfs)

As you can see the netfs service is the very last to be started, so it's also the very first to be shut down.

I think you should have rpcbind in there too, before nfs-common.

According to the Arch wiki entry for NFS rpcbind is started by the nfs-common script .

Do you have any mounted network drives? IIRC (and I've been meaning to do some tests but the situation doesn't occur very often, so I may be wrong - which is why I haven't reported it before), but I think my network is brought down before network mounts, so they then take ages to try and unmount on shutdown.

I do have that NFS mount yes. That unmounts manually within a few seconds (it's a 2 TB drive, NFS seems to notice that). The thing is the services are in the correct order; if the network somehow is shut down before the networked filesystems are that's a big design problem . You can see the 'network' service right at the start of my array as well.

The netfs shutdown routine hangs 100% of the time over here.

Are you using user,noauto in your mount options in fstab? Two of my shares are configured with those options. I have to unmount them manually before shutting down as netfs fails on them (why?) but unmounts the other nfs shares. Starting and stopping netfs from cli would fail whenever those two shares where mounted but using

umount.nfs <mountpoint>  -vlf

to unmount them worked. I now use /etc/rc.local.shutdown to unmount those two shares if mounted.
Not ideal but it worked.
Also, the nfs share is still up when you shut down on the AppleTV? Shutdown will hang at unmounting nfs stage if the server is down.

The server is up 24/7. It would be a bit silly to complain about the shutdown routine hanging when the server would cause timeouts by being shut down already .

This is my NFS entry:

amalthea:/var/data/video    /home/stijn/server/    nfs    ro,defaults,intr,auto,noatime,rsize=32768,wsize=32768,async,nfsvers=3    0    0

I do notice rpcbind is stopped *before* netfs. That does sound like asking for trouble to me...

rpcbind is started by nfs-common but not stopped by it. The shutdown routines call for all daemons not in the DAEMONS array to be stopped prior to those listed to be shut down. So, adding rpcbind to the daemons array should alleviate this issue.

I'll see how that works out, thanks .

Edi: that did the trick quite nicely, thanks falconindy .
