Appendix B. iSCSI Gateway Variables

iSCSI Gateway General Variables

seed_monitor
Purpose
Each iSCSI gateway needs access to the Ceph storage cluster for RADOS and RBD calls. This means the iSCSI gateway must have an appropriate /etc/ceph/ directory defined. The seed_monitor host is used to populate the iSCSI gateway’s /etc/ceph/ directory.
gateway_keyring
Purpose
Define a custom keyring name.
perform_system_checks
Purpose
This is a Boolean value that checks for multipath and LVM configuration settings on each iSCSI gateway. It must be set to true for at least the first run to ensure the multipathd daemon and LVM are configured properly.
