Finding object’s location
The Ceph client retrieves the latest cluster map and the CRUSH algorithm calculates how to map the object to a placement group, and then calculates how to assign the placement group to an OSD dynamically.
Prerequisites
-
A running IBM Storage Ceph cluster.
-
Root-level access to the node.
Procedure
To find the object location, all you need is the object name and the pool name:
Syntax
ceph osd map POOL_NAME OBJECT_NAMEExample
[ceph: root@host01 /]# ceph osd map mypool myobject
