Anyways, I'll start here and now: I have a FreeBSD8-RC2 server which I set up for nfsv4 serving according to nfsv4(4). I have a Linux client (Kernel 2.6.25) trying to do "mount.nfs4 / /mnt -v". This takes *exactly* 30s. (looks like running into some kind of timeout). After that, the mount is there. It is displayed by "mount" and gives the right sizes with "du -h". However, as soon as I try to access /mnt with "cd /mnt" or "ls /mnt" I get an Input/Output Error on the client side. Googleing around I found only very few information about nfsv4 and FreeBSD (ok, it's a new feature after all :-). Does anyone here already have some experiences to share? Anyone already using FreeBSD servers against Linux clients? Any suggestions how to debug and solve the problem above? Any hints are as always greatly appreciated. cu Gerrit
