[Solved] Nfs segfaulting with 3.0-ARCH

.:B:. · 2011-07-29 23:07:27

My Xbmc box is not mounting the NFS share anymore. This is how fstab looks:

amalthea:/video    /home/stijn/server/    nfs    rw,defaults,intr,auto,noatime,rsize=32768,wsize=32768,async,nfsvers=4    0    0

This is what I get when I call mount:

# mount.nfs4 -v 10.0.0.15:/video /home/stijn/server/
Segmentatiefout
[root@mnemosyne ~]# mount.nfs --help
Segmentatiefout
[root@mnemosyne ~]# mount /home/stijn/server/
[root@mnemosyne ~]# grep server /etc/mtab 
[root@mnemosyne ~]#

As you can see, nothing is mounted; mount just segfaults on the NFS mount; heck, it even segfaults on a simple --help call.

This is what everything.log has to say for it:

I checked the list of recently upgraded packages, so far nothing I can pinpoint as being the culprit (nothing NFS-related got upgraded in the past 5 days and this Xbmc is shut down and started daily, so it has to be a recent upgrade, if an upgrade is at fault at all).

Tried downgrading to nfs-utils 1.2.3-2, that didn't help.

Edit: I found this bug report, which means 3.0-ARCH scares the hell out of nfs-utils. Very nice.

Bah. I can't believe Google didn't pick that up. Thanks. Hopefully it works better than that patch I found. I think I'm putting my Xbmc box back on the LTS kernel though .

}

It searches ('string=$*') also the closed tasks and sorts the resulting list by ID so I get the fresh (usually more relevant) hits first.

Nice one. Thanks!
