File bug-474328_retry-export.patch of Package nfs-utils
From: NeilBrown <neilb@suse.de> References: bnc#474328 Subject: retry export if getfh fails. mountd tries to avoid telling the kernel to export something when the kernel already knows to do that. However sometimes (Exportfs -r) the kernel can be told to forget something without moutnd realising. So if mountd finds that it cannot get a valid filehandle, make sure it really has been exported to the kernel. This only applies if the nfsd filesystem is not mounted.
