I am having a similar problem, but with an IRIX nfs cluster, so hopefully we can triangulate. The linux client is, of course, Fedora Core 6, all patched up to date. The NFS server is part of a CXFS/Failsafe cluster, and I can mount shares on the linux system if I use the base hostname/IP address, but not when I attempt to mount via the IP alias address. The reason for the IP alias is to allow disconnect/relocation of cluster shares among cluster nodes (ie, move the filesystem export from one server to another)--that's failover. I'm currently thinking it's a security "feature" in FC6. I'm trolling the newsgroups, looking at tcpdump/snoop and rpcinfo output. -- This is an email sent via The Fedora Community Portal https://fcp.surfsite.org https://fcp.surfsite.org/modules/newbb/viewtopic.php?post_id=126940&topic_id=28750&forum=10#forumpost126940 If you think, this is spam, please report this to webmaster@xxxxxxxxxxxxxxxx and/or blame xian@xxxxxxxxxxxx
