Monitor Free Disk Space

It is critical that enough disk space is available on the server to avoid data loss so it is important to have a strategy that periodically monitors disk space and archives or deletes data as needed.

Disk Usage section

To access the Disk Usage section, click the Data tab and the Disk Management subtab:

Scroll down to the Disk Usage section:

Graph usage indicators

The Data -> Data Management tab section reports disk space usage for both server file systems and archive locations:

The color keys are explained in this table. The descriptions are based on the default disk usage threshold of 90%. (The threshold for the Signal Processing Input file category is used if your file categories have different thresholds.)

Usage totals

The Disk Usage section also reports space and usage totals for each file system. These totals appear to the right of the File server Space graphs in the Disk Usage section. (Totals for only one file system are shown here.)

The Raw Data and Reports totals correspond to these data Management file categories:

• Raw Data Signal Processing Input
• Reports Basecalling Input, Output, and Intermediate (combined)
  
  

Error messages

Monitor the Disk Space Management section for messages that require administrator action:

• Backup drive is full or missing Replace the backup drive.
• Error Check the file /var/log/ion/data_management.log for information regarding the specific error condition. If appropriate, report the error to Ion technical support.

Disk full messages

When any storage device reaches 95% full (and again at 99%), a warning banner is displayed across the top of Torrent Browser pages:

*** CRITICAL! /results/: Partition is getting very full - 95% ***

When the Torrent Browser UI is not available

Use the following procedure to monitor disk space when the Torrent Browser UI is not available:

1. Log into the server using an ssh client:
   
   

                  $ ssh ionadmin@ion-torrent-server
   $ password: ionadmin
                 

2. Enter the df command to display partitions and disk utilization:
   
   

                  $ df -h
   
   ionadmin@itw-test01:~$ df -h
   Filesystem         Size  Used Avail Use% Mounted on
   /dev/sda3          5.3T  372G  4.6T   8% /

   none                24G     0   24G   0% /lib/init/rw
   /dev/sda5           61G  524M   57G   1% /tmp
   /dev/sda1          276M   29M  233M  12% /boot
   /dev/sda4          3.8G  2.4G  1.3G  65% /var
   nas3:/c/results2   19T    17T  1.7T  91% /results2
   nas2:/c/archive/tahiti
                      19T    13T  5.3T  71% /media/archive
   nas1:/c/results    19T    17T  2.1T  89% /results4
   nas1:/c/results1   19T    16T  2.1T  89% /results3
                 

   
   
   Most growth is seen in the /results directories, which is whereIon Torrent data are stored.

The Use% column indicates how much space is being used.

Torrent Browser Data Management features

A disk space monitoring policy can be implemented using the Data tab's Disk Management subtab . See Data Management Overview and Archive or Export Analysis Files for more information about archiving and disk space management with the Torrent Browser.Additionally, your I.T. department may choose to deploy a monitoring tool such as Ganglia.

The admin menu Services tab also has a link to the Data tab's Disk Management subtab (scroll to the bottom of the Services tab for this link):
