I'm sorry to say this may well lie at the root of your problem. No matter how much the reiserfs proponents may protest otherwise the fs is not fully compatible with nfs.
Oh My GOD! Is this an opinion or authoritative? No. I'm not trolling or joking. I decided (on the last rebuild, relatively recently) to try Reiser on my primary file server.
It's a personal opinion. I performed tests with Bonnie and Bonnie++ on my cluster but I didn't see any bugs (I used nfsstat, netstat -s, ...). I only observed that when one client loaded the network with Bonnie++, the server became much less responsive to requests of other clients. (100 Mb/s Ethernet network, SUSE 9.1, smp kernels) Problems may exist but I don't think that NFS and Reiserfs are responsible for the mount failure. I've used NFS and Reiserfs since 9.0 and I haven't had a single problem related to mounting. -- A.M.
