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.

Red Hat Product Errata RHBA-2016:0735 0 normal SHIPPED_LIVE resource-agents bug fix and enhancement update 2016-05-10 22:28:24 UTC

Description Jaroslav Kortus 2013-10-29 19:53:30 UTC 
Description of problem:
Currently tmpfs is recognized as a supported filesystem of fs.sh resource.
This filesystem cannot work in current implementation ("none" device is not supported and later it requires fsck).

As probably no one has ever run it, we could drop it from the agent.

Version-Release number of selected component (if applicable):
resource-agents-3.9.2-40.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. add <fs device="/dev/loop0" fstype="tmpfs" mountpoint="/tmp/fstest" name="filesystem"/> to your cluster service
2.
3.

Actual results:
tmpfs cannot be mounted via rgmanager

Expected results:
message that tmpfs is not supported

Working patch
Comment 6 Oyvind Albrigtsen 2015-11-02 10:40:31 UTC 
Tested patch. Had to change the return code from OCF_ERR_ARGS as utils/fs-lib.sh thought that means success.

Updated working patch

Improved the patch and tested that it's working without any issues.
Comment 8 Oyvind Albrigtsen 2015-12-21 12:26:05 UTC 
Before:
- Error about none-device not being supported, or error when running fsck if device is set to e.g. /dev/loop0.

After:
- Message that tmpfs is not supported.
Comment 9 Oyvind Albrigtsen 2015-12-24 13:09:41 UTC
