FortiAnalyzer can receive logs and Windows host events directly from endpoints connected to EMS, and you can use FortiAnalyzer to analyze the logs and run reports.
This article describes how to troubleshoot issues with increasing the File System size beyond 16TB (ext3) or 64TB (ext4).
Scope
FortiAnalyzer-VM, FortiManager-VM.
Solution
After increasing the Virtual Machine disk size and performing 'execute lvm extend', the LVM size increases, but the File System size does not increase.
This can be verified using the following CLI command:
execute lvm info
LVM Status: OK
LVM Size: 75000GB
File System: ext4 500GB
Disk1 : Used 500GB
Disk2 : Used 70000GB
get system status
<truncated>
Disk Usage : Free 300.60GB, Total 500.60GB
File System : Ext4
License Status : Valid
This is due to the boundary limit of the File System:
ext3: 16TB.
ext4: 64TB.
To increase the ext3/ext4 'File System' beyond its boundary limit, the disk must be reformatted:
execute format <disk | disk-ext3 | disk-ext4>
Note:
This command will erase all data on the disk, including logs, configurations, and database files.
