Red Hat Bugzilla – Bug 262861
exportfs does not synchronize xtab with exports file
Last modified: 2007-11-30 17:12:14 EST
Description of problem:
Running "exportfs -av" or "exportfs -rv" does not synchronize /var/lib/nfs/xtab
with /etc/exports as it should according to the man page of exportfs.
The xtab remains always empty.
Version-Release number of selected component (if applicable):
$ rpm -qa | grep nfs
Steps to Reproduce:
1. export directory (/etc/export)
2. mount direcotry (other machine)
3. run exportfs
$ cat /etc/exports
$ /etc/init.d/nfs restart
Shutting down NFS mountd: [ OK ]
Shutting down NFS daemon: [ OK ]
Shutting down NFS quotas: [ OK ]
Shutting down NFS services: [ OK ]
Starting NFS services: [ OK ]
Starting NFS quotas: [ OK ]
Starting NFS daemon: [ OK ]
Starting NFS mountd: [ OK ]
$ exportfs -rv
$ echo $?
$ cat /var/lib/nfs/xtab
xtab is empty ..
... some conent about exported nfs directories
I red the man page of exportfs. From this I would expect some content for the
xtab file. Is this file simply not used anymore? If so, then a change of the
man page would be needed.
I searched also for other bugzillas about this problem, and I found only one ...
that mentioned this behavior at one comment. See bugzilla #165346 Comment #6.

Interesting... It turns out that when a new style of in-kernel
caching was added to both exportfs and mountd, the /var/lib/nfs/xtab
file is no longer used. The /var/lib/nfs/etab now the where
the export information is kept.
I've sent the attached patch to the maintainers for comment.
