Usage
Generate your key
In order to access to the object store you will need a Cephx key. See : https://api.grid5000.fr/sid/storage/ceph/ui/
Your key will also available from the frontends :
# curl -k https://api.grid5000.fr/sid/storage/ceph/auths/jdoe.keyring [client.jdoe] key = AQBwknVUwAPAIRAACddyuVTuP37M55s2aVtPrg==
Note : Replace jdoe by your login.
Create Ceph pool
Manage your pool from the Grid'5000 Ceph frontend : https://api.grid5000.fr/sid/storage/ceph/ui/
Configure Ceph on clients
On a deployed environment
frennes # oarsub -I -t deploy frennes # kadeploy3 -e ubuntu-x64-1404 -k -f $OAR_NODEFILE frennes # ssh root@node node # apt-get install ceph
Create a ceph configuration file /etc/ceph/ceph.conf :
[global] mon initial members = ceph0,ceph1,ceph2 mon host = 172.16.111.30,172.16.111.31,172.16.111.32
