OpenStack containerized Iscsid service
parameters:
ContainerIscsidImage:
description: image
type: string
ContainerIscsidConfigImage:
description: The container image to use for the iscsid config_volume
type: string
EndpointMap:
default: {}
description: Mapping of service endpoint -> protocol. Typically set
via parameter_defaults in the resource registry.

LVMFilterEnabled:
default: false
description: Enables configuration of LVM2 with a filter so that devices not
in use on the host or explicitly allowed are ignored by
LVM2. Can be configured per-role.
When disabled, the proposed lvm.conf file will be created
regardless and left in /tmp/tripleo_lvmfilter.conf for
debugging purposes.
type: boolean
tags:
- role_specific
LVMFilterAllowlist:
default: []
description: A list of block devices which should be allowed in the LVM2
`global_filter`. Supports regular expressions, like `/dev/sd.*`
and can be configured per-role. Any block device in use at boot
time will be automatically allowed.
type: comma_delimited_list
tags:
- role_specific
LVMFilterDenylist:
default: ['.*']
description: A list of block devices which should be disallowed in the LVM2

# NOTE(bogdando) Containerized or running on baremetal services

# However, overcloud nodes must have a unique IQN. Allow full

# is unique and is reset once, and only once.
# NOTE(abishop) The host directory is mounted at /tmp/iscsi.host
