NFS Server

Has anyone else had trouble with NFS serving since upgrading
to a recent 
kernel or compiler?

I just tried upgrading to vanilla-sources 2.6.15.1.  All
seemed well, until my 
diskless mythtv system started crashing.  It would appear to
be an NFS 
problem.  NFS works fine for a while, but after 10 to 15
minutes it locks up.  
This may be a function of the amount of data transfered.  I
also see problems 
when I mount NFS exports from the Alpha on my i386 SuSE 10.0
system.

Fearing a problem with the kernel version I tried to build a
new version of 
the old kernel (2.6.12.5), since I needed to add RAID. 
Bizarely and 
worryingly, this gives the same error.  This suggests that
something else has 
changed and the only thing I can think of is the compiler,
which I have 
probably upgraded since I built the working kernel.

Has anyone got a reliable Alpha NFS server with a recently
built kernel and if 
so which kernel and compiler versions did you use.

BTW, I have an LX164.

Thanks

I've seen exactly this problem on -2.6.15.1.

I downgraded back to 2.6.11.8 and all seems well again,
but I haven't done any stress-testing (yet).

Actually I'm having the same issue (using stuff exported by
an alpha and
mounted on a pc).  When that happens, just issuing a mount
command to a non
existing mountpoint will make nfs recover: assuming alpha
exports /foo, if
the pc has alpha:/foo mounted somewhere and hung, just
executing
mount alpha:/foo /somedirthatdoesntexist will make nfs works
again.  I've
posted on lkml and on linux-nfs but never got any reply.

Thanks, that has fixed the problem.  Since my exports are
being mounted by my 
diskless mythtv system, I can't easily log in to do the
remounts.  I have 
therefore written a little script which simply performs
remounts at regular 
intervals.

I will try with an older kernel and then post a bug report
to the Gentoo bug 
tracker.

Thanks,

Sweet.

Ugly but if it works...

Ok thanks.
