Technical Tip: FortiAnalyzer disk quota allocation per device
Description
This article describes the change in the FortiAnalyzer storage quota management introduced as of FortiAnalyzer v5.4.0 an more specifically the changes in the per-device quota allocation.
Scope
FortiAnalyzer v5.4.0 and above.
Solution
In FortiAnalyzer v5.0 and v5.2, the storage quotas were defined per-device and the log database quota was derived from the sum of all device quotas.
The device 'Disk Log Quota' was available in the GUI on the device Edit page in Device Manager:
In version 5.4.0, this was changed. The storage quota is now defined per-ADOM, to allow for easier management and better disk space utilization:
The per-device storage quotas were kept active for transition purposes, but only available to configure in the CLI.
Albeit still working, these device quotas are not meant to be used in the common cases, and it is recommended to be set to 'unlimited', as demonstrated below:
Disk quota allocation per device in v5.4 may be set through the CLI:
FAZ# execute log device disk-quota <device_id> <value>Where:
<device_id> The log device id (serial number), or 'All' for all devices. <value> Disk quota value in MB, 0 for unlimited.Example (with the the recommended 'unlimited'):
FAZ# execute log device disk-quota All 0 This will set all devices' disk quota to unlimited. Do you want to continue? (y/n)y Successfully set FWF61E4QXXXXXXXX disk quota to unlimited. Successfully set FGT60FTKXXXXXXXX disk quota to unlimited. Successfully set FGVM01TMXXXXXXXX disk quota to unlimited. Successfully set FWF60E4XXXXXXXXX disk quota to unlimited.
