What simple thing am I missing?

I am trying to demonstrate the effectiveness of using and SSD as a cache for NFS. I what to use FS-cache/cachefs combination, but I am running into a null pointer reference. As a "fall-back" for an upcoming demo, I tried using FS-cache/cachefiles. Everything to be working except it's not actually caching anything. This is on a Fedorea Core 12 system using the standard cachefiled package. The kernel and filesystem side is the latest stuff from the NFS group. I am transferring a 6 Gig. File and have an 8 Gig. partition for use by cachefilesd (with a Ext3 file system mounted with "user_xattr"). I have SELinux disabled. I am using a simulated network chocked back to 500Mbs/sec. When I df to track how much of the cache is being used, it shows that hardly any of it was used. Im not sure what to expect from "/proc/fs/cachefiles/histogram" but it shows very little: JIFS SECS LOOKUPS MKDIRS CREATES ===== ===== ========= ========= ========= 0 0.000 13 6 1 7 0.007 1 1 0 I'm stumped. I don't want to spend a lot of time on this because cachefs is my real focus. But I would like to have a fallback for the demo if I can't get cachefs debugged in time. Any help would be appreciated. Is there anything I could provide that could help figure out what's wrong? Thanks for any help, -=# Paul Gilliam #=- -- Linux-cachefs mailing list Linux-cachefs@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cachefs
