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 Vesselin Kolev 2010-05-06 22:12:02 UTC 
Description of problem:

When iser is used, librdmacm-devel should be installed to satisfy start-up dependencies:

(from syslog)
tgtd: librdmacm.so: cannot open shared object file: No such file or directory - iser transport not used

The bug is similar to another reported:

https://bugzilla.redhat.com/show_bug.cgi?id=589689


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

0.9.11-1.20091205snap.el6

How reproducible:

Always

Steps to Reproduce:
1. Make some iser based configuration in /etc/tgt/targets.conf
2. Start service (tgtd daemon):

# service tgtd start
  
Actual results:

Daemon starts, but error is logged in syslog.

Expected results:

Clean start with no errors of this kind.


Additional info:

librdmacm-1.0.10-2.el6 doesn't provide /usr/lib/librdmacm.so. The missing library is provided by librdmacm-devel-1.0.10-2.el6.
Comment 2 RHEL Program Management 2010-05-06 23:17:48 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 3 Bill Nottingham 2010-05-07 00:18:51 UTC 
It's preferable to  dlopen() the versioned file and require the library package, rather than the .so symlink and the -devel pacakge.
Comment 4 Mike Christie 2010-05-08 01:45:42 UTC 
I am going to mark this as a dup of 589689 since these errors are all under needing to make iser get installed correctly.

Comment 5 Mike Christie 2010-05-08 04:06:40 UTC 
Oh yeah,

To properly use dlopen like how Bill describes in comment #3, I am using this bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=590097

Actually, let me use this one for Bill's comment.

590097 is a different issue.
Comment 7 Mike Christie 2010-05-08 04:18:35 UTC 
I can replicate this here and here is the patch I am proposing to fix the problem where we require the devel packages when we only want the lib ones:
