After upgrade kernel at server from 2.6.38 to 2.6.39 series and higher, I was forced to drop to NFSv3. With NFSv4 I get (when I trying to read any file) hundreds message at client: Error: state manager failed on NFSv4 server base with error 10018 Now I have at server and cient: linux kernel 3.0.4 nfs-utils 1.2.3 nfs4-acl-tools 0.3.3 File /etc/exports: /opt 192.168.8.0/24(fsid=0,rw,subtree_check) ================================================== With version 3 ================================================== root|st01# mount -t nfs -o nfsvers=3 base:/opt /net root|st01# mount | grep nfs rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) base:/opt on /net type nfs (rw,nfsvers=3,addr=192.168.8.254) In other console: stas@st01$ ls -l /net/a* -rw-r--r-- 1 root root 35 Сен 21 11:23 /net/a_file.txt stas@st01$ cat /net/a_file.txt This is a test file on NFS share. stas@st01$ Works fine. ================================================== With version 4 ================================================== root|st01# umount /net root|st01# mount -t nfs base:/ /net root|st01# mount | grep nfs rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) base:/ on /net type nfs (rw,vers=4,addr=192.168.8.254,clientaddr=192.168.8.1) In other console: stas@st01$ ls -l /net/a* -rw-r--r-- 1 root root 35 Сен 21 11:23 /net/a_file.txt stas@st01$ cat /net/a_file.txt And the process hangs...
