Object storage operation tips
Public Ceph Documentation¶
The latest official documentation for ceph is available at http://docs.ceph.com/docs/master
The commands listed below can be run only from the platform operator accounts; from the administration servers. The ceph nodes themselves are not configured to operate the ceph cluster.
In this chapter, we assume the target ceph cluster is named
Checkout out your punchplatform.properties
file to determine the name of yours.
Checking the cluster status¶
ceph health --cluster main
Checking cluster used/free space¶
ceph df --cluster main
This will output:
- the global summed-up free/used storage space of all the cluster data nodes
- for each pool, the used space and the remaining storage space.
Remember that if you activated
erasure codingon a pool, the user data stored in the cluster will be smaller than the used storage space.
List data pools¶
ceph osd pool ls --cluster main
