exportfs does not export info to /proc/fs/nfs/exports
 

when i run exportfs -ra no information is exported to /proc/fs/nfs/exports nor to /var/lib/nfs/xtab.

so i can't mount my nfs shares

fedora core 5 kernel 2080.

any idea on why and how to fix it?

Is nfsd running?

what does /etc/exports look like?

In my case yes nfsd is running and the exports file is:

/home/ 192.168.1.100(rw,sync)

Is portmap also runing ?

Yes, every thing is properly configured, the only issue is that the file /proc/fs/nfs/exports is not being written to. Does anybody have any experience with that?

I have a similar situation. I have a machine that reports an empty /proc/fs/nfs/exports, and I'm also wondering what would cause this.

System is Red Hat 5.5, all services are chkconfig proper and running, with the only export right now being /home.

I was faced with the same issue on a CentOS machine, but in our case it was not OS related. We had moved the host to another domain (from host1.example.com to host1.bla.example.com).

It was strace that eventually told me what the problem was. We forgot to set the reverse to the new situation. exportfs looked up host1.bla.example.com, then did a reverse and found host1.example.com which could not be forward resolved. And thus it did nothing, leaving everything as is. No updates at all.

Resolving the reverse DNS issue solved the case. Hope this might help others with an identical situation.
