Ceph storage installation

Back to storage installation home.

In case of usage of Virtual Appliance
  • Use local account lpar2rrd for hosting of STOR2RRD on the virtual appliance
  • Use /home/stor2rrd/stor2rrd as the product home
It is already implemented. It will be released in Q3 2018.
Anyone willing to test it? Contact us at

The product uses REST API interfaces provided by the storage.


  • Start up REST API on some Ceph node under root user:
    [root@ceph1 ~]# nohup ceph-rest-api -n client.admin > /dev/null 2>&1 &
  • Storage connectivity:
    Allow access from the STOR2RRD host to the storage on port 5000.
    Test if porti is open:
    $ perl /home/stor2rrd/stor2rrd/bin/ 5000
      Connection to "" on port "5000" is ok

STOR2RRD storage configuration

  • All actions below under stor2rrd user (lpar2rrd on Virtual Appliance)

  • Uncomment (remove the hash) example line and adjust it:
    $ vi /home/stor2rrd/stor2rrd/etc/storage-list.cfg
    # Ceph
    # Storage Alias:CEPH:Storage IP address or hostname:PORT:VOLUME_AGG_DATA_LIM:VOLUME_AGG_IO_LIM:SAMPLE_RATE_MINS
    Above shows the storage with IP which will be visible in the UI as Ceph-alias01

  • Assure you have enough of disk space on the filesystem where is STOR2RRD installed
    Roughly you might count 2 - 30 GB per a storage (it depends on number of volumes, 30GB for 5000 volumes)
    $ df -g /home   # AIX
    $ df -h /home   # Linux
  • Check storage connectivity
    $ cd /home/stor2rrd/stor2rrd
    $ ./bin/ 
      STORAGE: Ceph-alias01 : CEPH   
      connection ok
  • Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there)
    $ crontab -l |
    Add if it does not exist as above
    $ crontab -e
    # Ceph 
    0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/ > /home/stor2rrd/stor2rrd/load_cephperf.out 2>&1
    Assure there is already an entry with the UI creation running once an hour in crontab
    $ crontab -e
    # STOR2RRD UI (just ONE entry of must be there)
    5 * * * * /home/stor2rrd/stor2rrd/ > /home/stor2rrd/stor2rrd/load.out 2>&1
  • Let run the storage agent for 15 - 20 minutes to get data, then:
    $ cd /home/stor2rrd/stor2rrd
    $ ./
  • Go to the web UI: http://<your web server>/stor2rrd/
