612862 – clvmd does not clean dlm lockspace on -S restart

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Fabio Massimo Di Nitto 2010-07-09 09:17:54 UTC

Version-Release number of selected component (if applicable):

lvm2-cluster-2.02.69-1.el6.x86_64

How reproducible:

always

Steps to Reproduce:
1. service cman start
2. service clvmd start
3. clvmd -S
4. service clvmd stop
5. service cman stop
  
Actual results:

[root@rhel6-node2 ~]# /etc/init.d/cman stop
Stopping cluster: 
   Leaving fence domain... found dlm lockspace /sys/kernel/dlm/clvmd
fence_tool: cannot leave due to active systems
                                                           [FAILED]

Expected results:

clvmd dlm lockspace should be cleared. It´s not possible to clear it even via cmd line.

dlm_tool leave clvmd reports success, but the lockspace seems to be unremovable.

Comment 1 Fabio Massimo Di Nitto 2010-07-09 09:20:02 UTC

small correction: repeating dlm_tool leave N times, will eventually remove the lockspace. Probably the counter is increased each time clvmd -S is executed.

Comment 3 RHEL Program Management 2010-07-15 14:32:37 UTC

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 4 Milan Broz 2010-11-16 14:13:48 UTC

This need some investigation but clvmd -S should not keep any additional references to resources.

Comment 5 Milan Broz 2011-01-18 17:34:48 UTC

Patch sent to list
https://www.redhat.com/archives/lvm-devel/2011-January/msg00130.html

Comment 6 Milan Broz 2011-01-19 23:13:06 UTC

Fix in upstream lvm 2.02.82.

Comment 8 Corey Marthaler 2011-04-06 16:21:28 UTC

Fix verified in the latest rpms.
