DDOS stores various log files inside the /ddvar filesystem.
To check the current space usage, the following command can be used, if logged into the system as a user with sysadmin privileges:
filesys show space
An example output from the above command is as follows:
sysadmin@DD# filesys show space

/ddvar 49.1 7.4 39.2 16% -
...
---------------- -------- -------- --------- ---- --------------
To check the current space usage using PowerProtect DD System Manager (DDSM) or the Graphical User Interface (GUI):
- Log in to DDSM/GUI as a user with sysadmin privileges
- Select 'Data Management' from the left hand menu
- Select 'File System' from the left hand submenu
- The information is displayed under the 'System Partitions' heading. For example:
Once the space utilisation for /ddvar reaches 75%, DDOS generates an alert. Typical space usage alerts seen for /ddvar are as follows:
- EVT-SPACE-00003: Space usage in /ddvar has exceeded 85% threshold.
- EVT-SPACE-00003: Space usage in /ddvar has exceeded 90% threshold.
- EVT-SPACE-00003: Space usage in /ddvar has exceeded 95% threshold.
- EVT-SPACE-00003: Space usage in /ddvar has exceeded 100% threshold.
- EVT-SPACE-00004: Space usage in /ddvar has exceeded 85% threshold.
- EVT-SPACE-00004: Space usage in /ddvar has exceeded 90% threshold.
- EVT-SPACE-00004: Space usage in /ddvar has exceeded 95% threshold.
- EVT-SPACE-00004: Space usage in /ddvar has exceeded 100% threshold.
Common causes for high space usage inside the /ddvar filesystem are:
- Old or redundant support bundles
- Old or redundant upgrade files
- Non-default CIFS log level The default CIFS log level is 1.
From DDOS 7.x, the following options exist to help address the above points:
- To list the support bundles present, the following command can be used, if logged into the system as a user with sysadmin privileges:
support bundle list
An example output from the above command is as follows:
sysadmin@DD# support bundle list

- To delete a support bundle, the following command-line syntax can be used, if logged into the system as a user with sysadmin privileges:
support bundle delete <name of support bundle obtained from 'support bundle list'>
For example:
support bundle delete DD-support-bundle-1120131912.tar.gz
- To list any DDOS package or upgrade files present, the following command can be used, if logged into the system as a user with sysadmin privileges:
system package list
An example output from the above command is as follows:
sysadmin@DD# system package list

------------------------------------------ ---------- ------ ---------- --------- --------
- To delete a DDOS package or upgrade file, the following command line syntax can be used, if logged into the system as a user with sysadmin privileges:
system package del <name of file obtained from 'system package list'>
For example:
system package del 7.11.0.0-1035502.rpm
- The default CIFS log level is 1. To check the CIFS log level, the following command line syntax can be used, if logged into the system as a user with sysadmin privileges:
cifs option show all
An example output from the above command is as follows:
sysadmin@dd3300-ddsupport# cifs option show all
All Options:

- To set or reset the CIFS log level to 1, the following commands can be used, if logged into the system as a user with sysadmin privileges:
cifs option reset loglevel
or
cifs option set loglevel 1
- To list any DDOS support bundles present via DDSM/GUI, the following steps can be used:
- Login to DDSM/GUI as a user with sysadmin privileges.
- Select 'Maintenance' from the left hand menu.
- Select 'Support' from the left hand sub menu.
- Select the 'Support Bundles' tab.
- For example:
- To delete a DDOS support bundle via DDSM/GUI, the following steps can be used:

- Select 'Maintenance' from the left hand menu.
- Select 'Support' from the left hand sub menu.
- Select the 'Support Bundles' tab.
- Mark a support bundle or multiple support bundles to be deleted by left clicking in the check box next to the file name. All support bundles can be marked by left clicking in the box to the left of the 'File Name' heading.
- Once a support bundle or multiple support bundles have been marked, click the "Delete" button.
- A prompt will appear listing the support bundle(s) to be deleted. To delete the marked support bundle(s), select the "OK" button.
