[Gluster-users] nfs problems

[David Lloyd]

getting lots of stale nfs filehandle errors

we have 4 nodes in our cluster, clients nfs mount the volume from any node
in a round-robin

it appears that one node has gone bad. the clients mounting that node can't
see the files that the others can see. ls -l gives rubbish for the metadata,
and get lots of these lines in the nfs.log:

Any ideas?

Thanks
