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.

Fixed In Version: ovirt-node-3.0.1-2.el6
Doc Type: Bug Fix
Doc Text:
The /usr/share/snmp/mibs directory was not writeable under the read only root, therefore custom snmp mibs were unable to be installed.The /usr/share/snmp/mibs directory is now read/write which means files can be placed under /usr/share/snmp/mibs now.

Description Udayendu Sekhar Kar 2013-08-07 09:43:07 UTC 
Description of problem:
Created a custom Mib file for the snmp on the rhev-h and added it to /usr/share/snmp/mibs/ directory and persisted it but post reboot the file is missing.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Virtualization Hypervisor release 6.4 (20130709.0.el6_4)

How reproducible:
100%

Steps to Reproduce:
# mount -o remount,rw /
# vi /usr/share/snmp/mibs/test-MIB.txt
# persist /usr/share/snmp/mibs/test-MIB.txt
# mount -o remount,ro /

Now reboot the host. Once the host will back you will not get the "test-MIB.txt" file but the entry is there under /config/files file.

Actual results:
After the host reboot the custom file is missing.

Expected results:
The custome file shouldn't erased after the server reboot as its already persisted.

devel thoughts

perhaps add this to the default persisted locations?  Can we do that in the plugin?  need to investigate why the file is getting dropped if it's persisted.

Comment 4 Joey Boggs 2013-08-27 01:41:01 UTC 
The file wasn't being mounted correctly due to the irregular directory path under /usr/share. If it was under any of the rwtab entries it would work fine.
