Description

This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Fixed. This not only allows us to query clvmd for cluster volumes (and the devices that makeup those volumes) at fence time, but also removes the need to keep a state file on each and every node in the cluster. Previously, we had to keep a state file which recorded all devices the node had registered with so that we could determine which devices to unregister with at fence time. There were many problems/limitations associated with this state file technique. Instead, the scripts now use the "--config 'global {locking_type = 0}'" option with all lvm commands. This fix required change to all three scripts related to SCSI reservations: scsi_reserve, fence_scsi, and fence_scsi_test. *** Bug 447465 has been marked as a duplicate of this bug. *** An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2008-0347.html |
