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 of problem:
configuration the kdump with unreachable nfs entry,there will output the exception message.
Version-Release number of selected component (if applicable):
rhev-hypervisor6.3-20121101.0.el6_3
How reproducible:
30%
Steps to Reproduce:
1.intstall the rhev-hypervisor6.3-20121101.0.el6_3 on one machine.
2.configure the host's kdump with unreachable nfs entry.
Actual results:
there will output the exception message like the "Device or resource busy '/etc/kdump.conf'"
Expected results:
there should be no these exception message output even configure it with invalid entry.
Additional info:analysis the source code,I find that after configure the kdump with unreachable entry,the system will remove the config file.but on the other hand,this file is using by some process. so it will appear this exception. I think this exception should be caught but not be threw.
