Re: Bug#753407: exportfs -r does not reexport shares for hosts with changed IPs

Hello,

Today one of my machines changed IP address and autofs stopped working as expected. I tried running exportfs -f on the server but that didn't help. I also tried export -a and export -r but still no result. The issue was resolved only when I removed the hostname in question from /etc/exports, reexport, then added it back and reexported again.

Best regards,

Hi,
Waiting doesn't help as sometimes I have waited for over two hours. I've also tried restarting nscd prior to reexporting and verifying that the server searches for the correct IP address. I think that I have tried the -f argument but I don't remember the outcome.

Currently I am away from the computers on a vacation and cannot test but I will try the -f switch and see what happens.

Thanks for helping.

Hi,

Does it help if you run 'exportfs -f'? (or wait about 15 minutes)

You can check the content of the various caches that nfsd uses in:
/proc/net/rpc

I've also recently discovered that /proc/net/rpc/auth.unix.ip/content contains the cache used by nfsd. You can flush that cache with the above command (or by writing the current time in seconds-since-epoch into the flush file).
