Please can you attach logs for pvs -vvvv and clvmd -d? Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. QA has not seen this issue with any of the latest rpms, closing. Will reopen if seen again. 2.6.32-198.el6.x86_64 lvm2-2.02.87-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 lvm2-libs-2.02.87-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 lvm2-cluster-2.02.87-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 udev-147-2.38.el6 BUILT: Fri Sep 9 16:25:50 CDT 2011 device-mapper-1.02.66-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 device-mapper-libs-1.02.66-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 device-mapper-event-1.02.66-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 device-mapper-event-libs-1.02.66-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 cmirror-2.02.87-2.1.el6 BUILT: Wed Sep 14 09:44:16 CDT 2011 |
