NFS client doesn't show all the files listed (ls -l) on an mount coming from an Solaris ZFS NAS server.

Issue

• NFS client doesn't show all the files listed (ls -l) on an mount coming from an Solaris ZFS NAS server, and happens at random timings.

• Once the shares are unmounted/mounted, the files show up again, but the problem re-emerges randomly.

# ls -al /workspace/lob5
total 6
drwxrwxrwx  10 sas1 sas     9 Jan 24 08:28 .
drwxrwxr-x+ 26 sas1 sas  4096 Jan 10 12:42 ..
dr-xr-xr-x   4 root root    4 Apr  3  2013 .zfs

• After remounting the NFSv4 mount directory, the listing seems fine.

• Other servers that have this NFS mount mounted do not seem to have this problem. These servers have the same mount options for the NFS mount:

rw,nosuid,bg,hard,rsize=65536,wsize=65536,actimeo=0,nointr,timeo=600,_netdev,tcp
