Hi After hours spend configuring the FS-Cache I've finally managed to get it running. I'm using version Cachefiles 0.7.2-3 and Fedora Core 6, Kernel 2.6.18. I've tried to setup a configuration where a FS-Cache Linux box can work as a caching proxy for Windows client that shall connect to an external data storage server thru a possible slow internet connection. This is the setup: NFSv4 Server --- (Slow Internet connection) --- [ NFSv4 Client + FS-Cache + Samba ] --- (Fast LAN connection) ---- Windows machines Machine 1 (Data storage): NfsV4 server Machine 2 (Proxy server): NFSv4 Client and Samba Server Machine 3...N (Windows clients): They connect to the Proxy server to get access to the NfsV4 server. The cachefiles + NFSv4 is working quite well, however, when the Windows machines connects to the Samba share the linux kernel fails badly. Is this possible with FS-Cache and if it is possible can anyone provide my with a working set of configuration files? Best regards Morten
