RHEL6: Stale NFS file handle in NFSv4 directory created off of NetApp qtree after writing to parent directory
Issue
- 'netapp_vol' is exported volume from 'filer', 'netapp_qtree' is a qtree created in volume and 'scripts' is a directory in qtree created with mkdir.
- The following sequence of operations produces
ESTALE
# mkdir /mnt/test
# mount -t nfs4 filer:/vol/netapp_vol /mnt/test
# cd /mnt/test/netapp_qtree/scripts/testing
# date > ../time.txt
# ls
ls: cannot open directory .: Stale NFS file handle
- Redirecting the 'date' command to the current directory (for example, $ date >>./time.txt) works ok.
- Running the command using absolute path works fine.
