SCSI "reservation conflict" on a High Availability cluster node?
Issue
- There are 2 nodes belonging to a Red Hat High Availability cluster. Sometimes a reservation conflict occurred with one of the disks, which caused I/O problems and, consequently, the service running on the node which was using that disk was stopped and a migration of the service to the other node has occurred.
