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 Justin Clift 2010-04-27 23:25:58 UTC 
Description of problem:

Installed rdma-1.0-6.el6.noarch from yum, however when starting the /etc/init.d/ script errors are reported for missing udev components:

***************************************************
[jc@storage1 rdma]$ sudo /etc/init.d/rdma start
Loading OpenIB kernel modules:/etc/init.d/rdma: line 142: udevtrigger: command not found
/etc/init.d/rdma: line 143: udevsettle: command not found
                                                           [  OK  ]
[jc@storage1 rdma]$

***************************************************

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

rdma-1.0-6.el6.noarch

How reproducible:

Every time.


Steps to Reproduce:
1. Install rdma package from RHEL6 beta repository via yum
2. Start rdma init script <-- Error occurs here
3.
  
Actual results:

The Infiniband kernel modules are loaded, but the rdma script throws errors.


Expected results:

The Infiniband kernel modules to load, but no errors to be thrown by the init script.

Comment 1 Justin Clift 2010-04-27 23:55:38 UTC 
On further investigation, this appears to be more serious than first thought:

a) udevtrigger was a part of the udev package in RHEL5, but the udev package in RHEL6 doesn't include it.  If this is due to an intentional change in udev, then the rdma init script will need updating.

b) The "ib_mthca" Infiniband hardware module (required for the Infiniband cards we use) is not loaded by the rdma script, though it is unloaded by it at shutdown.  This ib_mthca module needs to be loaded before the ib_ipoib module (also loaded by this init script) for IP over Infiniband interfaces to come up.

In RHEL 5, this appears to be done through udevtrigger, but isn't working now due to this bug.
Comment 3 RHEL Program Management 2010-04-28 01:15:20 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 4 Doug Ledford 2010-04-28 18:05:00 UTC 
The udevtrigger/udevsettle issue was already resolved in Fedora and the package simply needs reimporting into rhel6.  However, the udev dependency was not previously taken care of.  Both will be resolved prior to beta2.
Comment 5 Doug Ledford 2010-05-26 04:54:54 UTC 
Actually, the Requires: udev was already present, although it didn't require a late enough version.  The real problem was that the scripts still did udevtrigger and udevsettle instead of udevadm trigger and udevadm settle.  Switching the init script to use the preferred method of invoking udev and requiring a later version of udev in the rpm spec file solves the problem.
Comment 6 Gurhan Ozen 2010-07-14 19:01:34 UTC 
# rpm -q --requires rdma | grep udev
udev >= 145
Comment 7 releng-rhel@redhat.com 2010-11-10 21:28:19 UTC 
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
