NFS locks after mounting

[br24]

Binary package hint: nfs-common

I have multiple NFS shares on my NFS server, and every time I mount one or more share, nautilus will lock when attempting to access the mounted share, samba locks up on every networked system, and the directory on the server will lock up. Both NFS server and client have been upgraded to Intrepid, and the last time I did not have a problem was when the server was on Gutsy, with the client already upgraded to Intrepid.

The shares I attempt to mount are located on an external drive, which uses the FAT file system. The client previously had the shares in fstab, which worked before upgrading the server. I have also reinstalled Intrepid on both systems without success. I have attempted to kill nfs-common and portmap on the client, and nfs-common, nfs-kernel-server, and portmap on the server, and both were unsuccessful in resolving this. The only way I can access the external drive on the server and via samba is to restart both client and server.

Here is the input on /etc/exports on the server, with "192.168.x.x" as the IP for the client:

/media/Storage 192.168.x.x/32(rw,no_root_squash,async)
/media/Storage/Music 192.168.x.x/32(rw,sync)
/media/Storage/Pics 192.168.x.x/32(rw,sync)
/media/Storage/VG 192.168.x.x/32(rw,sync)

I am running out of ideas on resolving this, and I believe this could be an issue with 2.6.27-9-generic kernel, as it is the only thing I can think of at this time.

Here are additional information on both client and server:

(client) brian@Milo:~$ uname -a
Linux Milo 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 GNU/Linux

(server) brian@Sassy:~$ uname -a
Linux Sassy 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 GNU/Linux

I am also attaching files giving additional information.

Thank you for reporting this bug. Could try adding "no_subtree_check" to the options in the export file? When I upgraded from 7.10 to 8.04, I found this to be the only way I could access my NFS shares. Thanks in advance.

Thank you for the reply. I added "no_subtree_check" and "async" to this last three options, while removing the first. I received the same results. I successfully mounted the first share without any issues, then mounted the second. I then checked Samba on a Windows system, and it was locked up. I also tried to access the ext drive on the NFS server, and that was locked up as well.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here.
