linuxgeek: [nslu2-linux] NFSD: unable to find recovery directory /var/lib/nfs/v4recovery

Hi,

Unfortunately my slug got knocked off the shelf when my (ill) cat failed to jump onto the shelf. As a result it had a power-cycle without correct shutdown and I now find I'm having trouble exporting (and mounting from a client) my NFS directories.

I see in dmesg....

eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
Installing knfsd (copyright (C) 1996 okir@monad.swb.de).
NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory
NFSD: unable to find recovery directory /var/lib/nfs/v4recovery
NFSD: starting 90-second grace period

and from the client I get permission denied on all directories...

# /etc/init.d/netmount restart
* Caching service dependencies ... [ ok ]
* Unmounting network filesystems ... [ ok ]

mount.nfs: access denied by server while mounting slug:/mnt/work2
mount.nfs: access denied by server while mounting slug:/mnt/ref
* Could not mount all network filesystems [ !! ]

I found a suggestion of adding the 'nolock' option to /etc/exports but I'm told this isn't recognised (and its not listed in the man page for /etc/exports either).

Currently my /etc/exports looks like...

# /etc/exports: NFS file systems being exported. See exports(5).
## /usr/portage
/mnt/portage 192.168.1.0/255.255.255.0(rw,async,subtree_check,no_root_squash)

## misc

## work
/mnt/work2 192.168.1.0/255.255.255.0(rw,async,subtree_check)
## ref
/mnt/ref 192.168.1.0/255.255.255.0(rw,async,subtree_check)

The versions of NFS (and modules) I have installed are...

# opkg list_installed | grep nfs
kernel-module-nfs - 2.6.27.8+svnr1085-r3 -
kernel-module-nfsd - 2.6.27.8+svnr1085-r3 -
nfs-utils - 1.1.2-3 -

I get the impression that there is a lock on NFS exports due to the unclean power-cycle, but have no idea how to get round this.

Advice appreciated,

Cheers

Neil
