Hi I have spent days trying to use cachefilesd with NFSv4 through a SSH-tunnel. However, whatever I do cachefiles just seems to die badly with an errno 95 error message. Please find the system details at the end of this mail. Any help will be greatly aprreciated. Best regards Morten Linux version Fedora Core 6, kernel 2.6.18 Cachefilesd I have tested with cachefilesd 0.8.15 and 0.7.2 with the same results Cachefilesd configuration file dir /var/fscache tag mycache brun 10% bcull 7% bstop 3% Mount of caching directory with resides in it's own partition which is newly formatted /dev/sda3 on /var/fscache type ext3 (rw,user_xattr,acl) Mount of NFSv4 directory through a SSH-tunnel mount -t nfs4 -o rw,hard,intr,proto=tcp,port=8888,noauto,fsc 127.0.0.1://mnt/nfs Results from running cachefilesd >> /sbin/cachefilesd -dsn About to bind cache Bound cache Daemon Started Scan complete Refilling cull table Failed to check object's in-use state: errno 95 (Operation not supported)
