After adding a new disk to the server and creating a Chunk Server on it, it doesn't appear to be available in the Cloud Storage cluster:
[root@pcs1 ~]# pstorage -c pcs1 make-cs -r /pstorage/pcs1-cs2/data [root@pcs1 ~]# pstorage -c pcs1 list-services TYPE ID STATUS DEVICE/VOLUME GROUP DEVICE INFO PATH CS 1025 running  /dev/sda6 HUS154530VLS300 /pstorage/pcs1-cs/data CS 1026 running  /dev/sdb6 HUS154530VLS300 /pstorage/pcs1-cs1/data CS init stopped /dev/sdc1 ST3600057SS /pstorage/pcs1-cs2/data
Newly created Chunks Servers cannot be added to the cluster on the fly.
# service pstorage-csd restart
The operation will suspend all write operations to the local Chunk Servers. This may be crucial in case the replication level of the cluster is set to 1 or the server is the only one in the cluster.
In order to enable CS hotplug, it's necessary to adjust the configuration of the
pstorage-hotplug daemon. Check
man pstorage-hotplug for more information.
