Some time ago i reported receiving this error in a knfsd 1.4.4 and later setup with kernels 2.2.7 and above. This happened only under extreme stress in the 100GB+ nfs export - at night during a backup with Arkeia, in this case. I was asked to patch the kernel with the following patch, in order to get some information about the moment it happens. The patch is:
--- nfsfh.c.orig Thu Jul 15 20:37:20 1999 +++ nfsfh.c Thu Jul 15 20:37:55 1999 @@ -1143,6 +1143,10 @@ printk("nfsd Security: %s/%s bad export.\n", dentry->d_parent->d_name.name, dentry->d_name.name); + printk("nfsd Security: %p %p %p.\n", + exp->ex_dentry, + tdentry, + dentry); goto out; } }
Anyway, it finally happened, after almost two months. To fix it was only a matter of restarting nfs. No reboot needed. The results were:
Sep 6 22:34:59 jerry kernel: nfsd Security: /// bad export. Sep 6 22:34:59 jerry kernel: nfsd Security: c0083e60 d0621140 d0621140. Sep 6 22:35:00 jerry kernel: nfsd Security: /// bad export. Sep 6 22:35:00 jerry kernel: nfsd Security: c0083e60 d0621140 d0621140. ... ... ... Sep 7 06:46:14 jerry kernel: nfsd Security: /// bad export. Sep 7 06:46:14 jerry kernel: nfsd Security: c0083e60 d0621140 d0621140.
I hope it helps someone to solve the problem. It is the only problem we have been having with it in a heavily used server. And it only happens each two months or so.
