FC3 and FC4 have now been EOL'd. Please check the ticket against a current Fedora release, and either adjust the release number, or close it if appropriate. Thanks. Your friendly BZ janitor :-) The cfs package has been dropped from Extras. |
Description of problem: Cannot start cfsd at boot-time with new 2.6.13 and 2.6.14 kernels. Version-Release number of selected component (if applicable): kernel-2.6.13-1.1526_FC4 kernel-2.6.13-1.1532_FC4 kernel-2.6.14-1.1637_FC4 cfs-1.4.1-6.fc4 nfs-utils-1.0.7-12.FC4 This has been verified on i686 platforms. How reproducible: Always Steps to Reproduce: 1. Enable nfs with 'chkconfig nfs on' 2. Enable cfsd with 'chkconfig cfsd on' 3. Reboot 4. Attach a CFS share with 'cattach' Actual results: Initial cfsd mount request at boot-time times out, and CFS is unusable for the machine after the machine finally does boot -- the cattach command fails. Expected results: CFSD should start at boot-time, and users should be able to 'cattach' CFS shares as soon as the machine boots. Additional info: This issue seems to coincide with the new kernel NFS stack that reports the mysterious "NFSD: starting 90-second grace period" message. As an experiment, I inserted a delay into the /etc/rc.d/init.d/cfsd script that starts it *after* nfsd, and waits 90s before attempting to mount its /.cfsfs directory. That didn't work. I extended the timeout to 120s, and it started working. This problem doesn't seem to affect autofs, which is the other NFS-dependent service I'm starting at boot-time. The problem also cannot be reproduced on an already-running system. I tried to shutdown affected services: autofs cfsd nfs rpcidmapd portmap and remove NFS-dependent modules: modprobe -v -d nfs modprobe -v -d nfsd Re-enabling the above services prints the same kernel message ("NFSD: starting 90-second grace period") but this time, cfsd starts up right away and the 'cattach' command works.
