Description Dave Maley 2010-10-19 18:44:34 UTC 
Created attachment 454409 [details]
util-linux-ng-2.17-rnetdev.patch

Description of problem:
Start of kdump service fails in RHEL6 iSCSI boot environment.  The kdump
service starts successfully in RHEL5 when _rnetdev option is specified for
/boot in fstab.

The _rnetdev mount option was added in RHEL5.2 to address problems where the
iscsi root device never got fscked.  The _rnetdev support added to util-linux in
5.2 (bug 435722) is missing from util-linux-ng in RHEL6.


Version-Release number of selected component (if applicable):
util-linux-ng-2.17.2-6.el6


How reproducible:
always


Steps to Reproduce:
1. setup system w/ iSCSI boot environment
2. configure kdump (if not auto-enabled)
3. reboot (if crashkernel memory not already reserved)

  
Actual results:
kdump service fails to start


Expected results:
kdump service starts successfully

Grr... the patch has never been added to Fedora or upstream. It was always RHEL specific.
Comment 4 Dave Maley 2010-10-20 15:45:10 UTC 
note: the support for _rnetdev in util-linux was added to 5.2 in order to fix fsck on iscsi root devs (bug 435722).  However the customer who reported it against RHEL6 noticed it because it broke kdump in their iscsi boot environment.  I've updated the summary to (hopefully) more accurately describe this bug report.
