Subject: nfs4 hang
Date: Thu, 20 May 2010 15:54:28 -0400 (EDT) [thread overview]
Message-ID: <25273515.321274385268620.JavaMail.javamailuser@localhost> (raw)

Hello,
I have a bash script that sets up a root filesystem over NFS. The method works fine over NFS3 but hangs when using NFS4 as a transport. Hoping someone can help me figure out why?
In a nutshell:
1. The node boots into a ramdisk that has a few thousand files in it already
2. connects to an NFS server exporting / and mounts that in a tmp dir
3. bash (on the booting node) loops through the local and remote filesystem and creates a local symlink to anything in the nfs root that it doesn't already have.
Export options are: / 192.168.1.0/24(rw,no_root_squash,no_subtree_check,fsid=0)
Mount options are: rw,sync,noatime,rsize=1024,wsize=1024
rpcidmapd, portmap, statd are running on server and client, and rpc_pipefs is mounted on both as well. The script currently makes about 6200 links, total. Nfs4 hangs about 90% of the way through. I removed the directory it was hanging on (a simple, empty dir) and then it just hung on the next one.
Really appreciate any help or pointers on where to look for more info. Thanks!
Chris
