Red Hat Bugzilla – Bug 249918
nfs server no longer mountable
Last modified: 2007-11-30 17:12:11 EST
Description of problem: After upgrading kernel I can no longer serve NFS shares. Version-Release number of selected component (if applicable): kernel-2.6.22.1-33.fc7.x86_64 (the server side) (client side tested either this one or kernel-2.6.21-1.3228.fc7.x86_64) nfs-utils-1.0.12-4.fc7.x86_64 nfs-utils-lib-1.0.8-8.fc7.x86_64 How reproducible: Not tried again. Steps to Reproduce: 1. /etc/exports: /home 172.20.0.2(rw,no_root_squash,async) 2. service nfs restart 3. export -rav 4. client: mount -tnfs -o rw,hard,nointr,rsize=4096,wsize=4096,suid,dev,async 172.20.0.1:/home /home Actual results: server: Jul 27 22:57:05 host0 mountd[22959]: authenticated mount request from virt:985 for /home (/home) client: mount: 172.20.0.1:/home failed, reason given by server: Permission denied Expected results: Successfully mounted share. Additional info: Attached a pcap dump just showing ERR_ACCESS on the packet level. Simple reboot of the server side back to kernel-2.6.21-1.3228.fc7.x86_64 fixed the problem.
Created attachment 160143 [details] .pcap of the unsuccessful mount attempt.
Could this is a duplicate of bug 249857. I see this too when I try to mount file systems from a freshly booted machine running kernel kernel-2.6.22.1-33.fc7. But after two hours, it is possible to mount from it. I'm in UTC +0200. I'll shortly upgrade to kernel-2.6.22.1-41.fc7 and see if it solves the problem, but I thought I'd mention this here right away.
After upgrading to -41 this no longer happens. It does indeed seem to be the same problem. *** This bug has been marked as a duplicate of 249857 ***
