Installation

FreeNAS, TrueNAS

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
STOR2RRD uses REST API interface natively provided by the storage to get all necessary data.
Supported are FreeNAS firmwares 11.2+.

Storage connectivity

  • Allow access from the STOR2RRD host to the storage on port 443 (80 in case http)
    $ perl /home/stor2rrd/stor2rrd/bin/conntest.pl 192.168.1.1 443
      Connection to "192.168.1.1" on port "443" is ok
    
  • Storage user: root account must be used, unfortunately only root can connect REST API.

STOR2RRD storage configuration

  • Add storage into configuration from the UI:
    Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ iXsystems : FreeNAS
    Storage management

  • 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
    
  • Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there)
    $ crontab -l | grep load_freenasperf.sh
    $
    
    Add if it does not exist as above
    $ crontab -e
    
    # FreeNAS, TrueNAS  
    0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_freenasperf.sh > /home/stor2rrd/stor2rrd/load_freenasper.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 load.sh must be there)
    5 * * * * /home/stor2rrd/stor2rrd/load.sh > /home/stor2rrd/stor2rrd/load.out 2>&1
    
  • Let run the storage agent for 15 - 20 minutes to get data, then:
    $ cd /home/stor2rrd/stor2rrd
    $ ./load.sh
    
  • Go to the web UI: http://<your web server>/stor2rrd/
