Description Nate Straz 2010-05-26 16:11:23 UTC
Description of problem: While trying to debug a startup hang I wanted to use the "-d 2" option to dump debug messages to syslog while starting up as normal. Unfortunately clvmd does not run in the background in this case. Version-Release number of selected component (if applicable): lvm2-cluster-2.02.65-1.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. clvmd -d 2 2. clvmd should continue running while returning you to the command prompt. Actual results: clvmd runs in the foreground Expected results: clvmd run in the background Additional info:
Comment 1 Nate Straz 2010-05-26 16:12:00 UTC
From the man page for clvmd: OPTIONS -d [<value>] Enable debug logging. Value can be 0, 1 or 2. 0 disables debug logging in a running clvmd 1 sends debug logs to stderr (clvmd will not fork in this case) 2 sends debug logs to syslog If -d is specified without a value then 1 is assumed if you are starting a new clvmd, 2 if you are enabling debug in a running clvmd.
Comment 2 Christine Caulfield 2010-05-26 16:17:35 UTC
The real problem is the -d is overloaded. there should be a separate flag to indicate to clvmd that it should not fork.
Comment 4 Nate Straz 2010-05-26 16:51:38 UTC
Can this be fixed as documented so I can debug startup timeouts?

This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. **
Comment 8 Milan Broz 2010-11-16 14:03:54 UTC
There should be new option (as already mentioned in comment #2).

(In reply to comment #0) > Steps to Reproduce: > 1. clvmd -d 2 > 2. clvmd should continue running while returning you to the command prompt. One important note: Please be aware of the fact that you have to use "clvmd -d2" not "clvmd -d 2" (leave the space out!).
Comment 12 Corey Marthaler 2011-04-06 18:59:32 UTC
Fix verified in the latest rpms. * Note: like mentioned in comment #10, "clvmd -d2" not "clvmd -d 2" is what's required for this to work. "clvmd -d 2" evals to no argument, and thus is the same as -d1. 2.6.32-128.el6.x86_64 lvm2-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 lvm2-libs-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 lvm2-cluster-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 udev-147-2.35.el6 BUILT: Wed Mar 30 07:32:05 CDT 2011 device-mapper-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 device-mapper-libs-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 device-mapper-event-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 device-mapper-event-libs-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 cmirror-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011
