[Linux-cachefs] [Q]: NFS + CacheFS hangs.....

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi.....

I have been trying to setup a machine to use NFS with CacheFS, but when I run mount -o fsc nothing happens.....the machine keeps working and is reachable over the net, but the NFS filesystem never mounts, and the command just sits there. Also, it won't respond to Ctrl-C and I can't reboot or halt the machine.....shutdown, reboot, halt, init 6 etc. have no effect....my only option is to power the machine down manually.

The details of the machine are

OS: Fedora Core 2
Kernel: 2.6.12-rc2
Patches: Andrew Morton's 2.6.12-rc2-mm3 patches applied (downloaded from kernel.org) and Steve Dickson's NFS for FSCache patches as posted to this list on 9th May. Misc: Updated util-linux with Steve's updated packages with the fsc mount option.

Of course I also created the filesystem cache block device with an echo "cachefs___" > <device> and I mounted it with the -t cachefs option.

I have also found that if the fscache block device is not mounted, I can mount the NFS filesystem (even with the fsc option) just fine. If I then mount the fscache block device and try to cd to a directory on the NFS mounted filesystem, the 'cd' command hangs the same as the 'mount -o fsc' above.....and the machine behaves in exactly the same way....

I am not sure if its relevant, but I am NOT using NFS4.....

I was just wondering if anyone would have any suggestions as to why this might be happening or if perhaps I missed something?

Thanx muchly in advance for any help.

Chris Bradshaw.
