Hello,
Much like the issues Chris had I have run into the same. I am using fc3 all the latest packages updated through yum. My kernel was prepared the same way as Steve suggested:
"I started with the linux-2.6.11 tarball then applied the patch-2.6.12-rc3.bz2
patch and the 2.6.12-rc3-mm3.bz patch". The util-linux patches were then forced
from http://people.redhat.com/steved/cachefs/util-linux/. I have setup the cache
block device, initialized it, all that goes well until NFS hits the equation.
As soon as I try to mount NFS with the fsc option it just hangs there, cant kill
the process, cant reboot the machine, same issues. Has there been any progress
towards a solution?
I would be good to see where the mount is hanging...
use "echo t > /proc/sysrq-trigger" to dump a system
trace to /var/log/messages. That tell where the hang
is occurring.
Can we expect this to be fixed in the new version David announced a few days ago?
Well these are the "next generation" patches. Meaning these will be
replacing the current patches in the -mm and the ones that we will
be porting to FC/RHEL kernels... So it might make sense to migrate
to them.
I tried to load this on another system, Core 2, a few weeks back and was able to
mount the nfs with the fsc option. As soon as I initiated any type of traffic to
the mount (10megs of web traffic from the frontend, CachFS machine, to the
backend via NFS mounted with fsc) the system load shot up to the 100's and
the machine came crashing down.
Again, having the oops output would be helpful....
