- How about running the '/usr/etc/exportfs -a' command to resync the
- /etc/exports file with the /etc/xtab file.
-
- Additional flags on the /usr/etc/exportfs command are:
- -a All. Exports all directories listed in the /etc/exports file.
- -v Verbose. Prints the name of each directory as it is exported or
- unexported.
- -u Unexports the directories you specify. If used with -a, unexports
- all directories.
- -i Ignore /etc/exports file and exports the directory specified
- on the command line.
- -o options for the exported directory.
-
- Possible problems on NON-WORLD exported file systems could be:
-
- Check that the 'host' command can resolve system names correctly.
- Enter 'host hostname' and check that it show IP address correctly.
- THEN.. try 'host ip.addr' using that hosts IP address and make sure that
- the hostname for that IP addresses is correct. This is VITAL for any
- filesystem that is NOT exported WORLD. Insure that multihomed (more than
- one network interface card) machines have ALL IP addresses for that host
- resolve correctly back to the SAME hostname that was specified in the
- /etc/exports file. If running YP or DNS, you might need to specify the
- fully qualified hostname in the /etc/exports file.

- Wipping out my RT NFS manual and looking on the cover I see:
-
- IBM AIX/RT Network FIle System Version 1.2
- AIX/RT Network FIle System Reference Guide
- First Edition (March 1990)
-
- Manual number is: SC23-2321
-
- IBMLINK online PUBS lookup indicates that the manual has been obsoleted
- as of 05/92. (It cost $22.00 U.S. Dollars originally).
-
- It may not be available for purchase anywhere other than on a asis stock basis.
