All clients can’t import
from a given server
(cont’d)
On the server (cont’d):
• exportfs -a
(to force the server to re-read /etc/exports and export the
file systems specified in it).
• Run SAM and get into the “Services Enable/Disable” menu
under “Networking/Communications”, click on “NFS Server”
and choose “Restart” from the pull-down menu.
• If these remedies fail, and the configuration looks good (all
the checks above), then the server may not have booted
correctly; try rebooting the server.
Stale NFS file
handle
(Common on NFS
clients after server has
crashed, or been
rebooted before clients
have unmounted NFS
file systems, or after
/etc/exports has
been changed on the
server).
On the client(s):
• Check that there are no open files in the affected file systems,
then try unmounting and remounting them.
Try this first if /etc/exports has been changed on the
server (directly or via SAM).
On the server:
• exportfs -a
Try this first if server has just rebooted.
On an NFS server,
umount fails.
• Check that all files are closed in the file system to be
unmounted, and that it is not anyone’s working directory, on
the system (host) from which it is to be unmounted. Note
that although fuser (1M) can be used to check for open files, it
is not able to detect files in a different directory opened
within an editor.
• Try this if the directory is exported:
exportfs -u dir
