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.

vdsm logs

Description of problem:
When a domain is not reachable, during the attempt to stop the domain monitor for that domain, the following is visible in the vdsm logs:

Thread-45::DEBUG::2012-09-06 13:01:15,768::domainMonitor::150::Storage.DomainMonitorThread::(_monitorLoop) Stopping domain monitor for 64bfae48-2ccd-4c05-b523-1fdeb90f4d2c

Traceback (most recent call last):
  File "/usr/share/vdsm/storage/domainMonitor.py", line 156, in _monitorLoop

This error does not seem to affect the operation itself, but should probably not be written to the log

Version-Release number of selected component (if applicable):
vdsm-4.9.6-32.0.el6_3.x86_64


Steps to Reproduce:
1. Block connection between host and non-master storage domain
2. AttributeError should be visible in the logs

  
Actual results:
AttributeError is visible in the logs

Expected results:
AttributeError should not be printed to the logs

Additional info:
Comment 2 Federico Simoncelli 2012-09-13 15:48:59 UTC 
DomainMonitor shouldn't releaseHostId if the domain is missing

In this patch:
* do not release releaseHostId if the domain is missing
* improve the checks for produce() and isIsoDomain()
