Issue the startup script again: [root]# /usr/atria/etc/clearcase start ClearCase daemons: albd_server mount_mvfs: File exists Trouble mounting the viewroot "/view"(16:29) Mounting public VOBs... Stop ClearCase: [root]# /usr/atria/etc/clearcase stop Unmounting VOBs... ERROR: Module mvfs is in use Trouble unloading the mvfs module(8:1) A reboot of the server will clear the issue.

ClearCase dead but subsys lock 1429843; CC; atria_start; start; stop; albd; Red Hat; ClearCase dead but subsys locked; start; stop; deadlock; lock Technote (troubleshooting) Problem(Abstract) This technote explains how to resolve an issue that can occur when starting and stopping IBM Rational ClearCase where if the start script is run twice or run too soon after stop, the ClearCase albd server can become locked and log the error, ClearCase dead but subsys locked. Symptom You receive the following messages when stopping and starting ClearCase: # atria_start stop Unmounting VOBs... http://www.ibm.com/support/docview.wss?uid=swg21389091 ERROR: Module mvfs is in use Trouble unloading the mvfs module(8:1) After attempting failed stop, then start up is also unsuccessful; # atria_start start http://www-01.ibm.com/support/docview.wss?uid=swg21429843 ClearCase dead but subsys locked Cause The Linux startup script (atria_start) has faulty logic. This issue has been identified as a product defect under APAR PM12376. The script included with older versions of ClearCase had some inconsistent logic in how it determines that ClearCase is active and creates a lock that it neglects to remove and which can only be removed by restarting the server. Environment Seen in various Red Hat servers after an install attempt. or when stopping and starting some services to change VOB registration details during a VOB move, or by running the start script twice in rapid succession. Resolving the problem This defect has been resolved. Refer to APAR PM12376 for further details. WORKAROUND The workaround is to manually remove the lock: # rm -f /var/lock/subsys/clearcase then restart ClearCase.
