Procedure when CVMFS fails in a UI
- Identify the 4 CVMFS processes
[root@m3 ~]# ps ax|grep cvmfs 19206 ? S 0:00 /usr/bin/cvmfs2 <u>cachemgr</u> . 8 9 8388608000 4194304000 0 3 -1 : 19208 ? S 0:00 /usr/bin/cvmfs2 <u>cachemgr</u> . 8 9 8388608000 4194304000 0 3 -1 : 19211 ? Sl 0:00 /usr/bin/cvmfs2 -o rw,fsname=cvmfs2,allow_other,grab_mountpoint,uid=105,gid=108 cms.cern.ch /cvmfs/cms.cern.ch 19215 ? S 0:00 /usr/bin/cvmfs2 -o rw,fsname=cvmfs2,allow_other,grab_mountpoint,uid=105,gid=108 cms.cern.ch /cvmfs/cms.cern.ch
- Kill them
[root@m3 ~]# kill -9 19206 19208 19211 19215
- CVMFS should work after few seconds

When the above fails
If there is no cvmfs daemon running, you might find the following message in /var/log/messages
failed to initialize root file catalog (16 - file catalog failure)
In that case, you can restore the system with a reload of the cvmfs config:
cvmfs_config reload -c
After this step, you might have to restart autofs though. Template:TracNotice
