# Generate a CRUSH location for the given entity
|
||
|
|
#
|
||
|
|
# The CRUSH location consists of a list of key=value pairs, separated
|
||
|
|
# by spaces, all on a single line. This describes where in CRUSH
|
||
|
|
# hierarhcy this entity should be placed.
|
||
|
|
#
|
||
|
|
# Arguments:
|
||
|
|
# --cluster <clustername> name of the cluster (see /etc/ceph/$cluster.conf)
|
||
|
|
# --type <osd|mds|client> daemon/entity type
|
||
|
|
# --id <id> id (osd number, mds name, client name)
|
||
|
|
#
|
||
|
|
|
||
|
|
# if we start up as ./ceph-crush-location, assume everything else is
|
||
|
|
# in the current directory too.
