How to share device in a cluster across multiple hosts?
Issue
- 1) Clustering requires a storage device to be shared across nodes. Currently OpenStack doesn't support sharing cinder volumes across multiple nodes. Multiple_attach_Volume
- 2) Veritas requires SCSI3 PGR support for IO fencing. It is unsure whether the ISCSI exports from cinder node do support SCSI3 PGR or not.
Environment
- Red Hat OpenStack 5.0 on RHEL 7
