Description
This article describes how to format an SDA disk partition to erase all data on it, including disk logs, quarantine files, and WanOpt caches.
Scope
FortiGate.
Solution
The SDA partition stores disk logging, disk logs, quarantine files, and WanOpt caches.
CLI syntax:
dia hardware deviceinfo disk <- To verify the SDA and SDB disk size and partition number.
Disk HDD1 ref: 255 55.9GiB type: SSD [ATA ADATA SX1000L] dev: /dev/sda <- This SDA disk partition is used for disk logging, cache examples, WAN optimization etc.
partition ref: 1 55.0GiB, 40.0MiB free mounted: Y label: 3243655A2DA69767 dev: /dev/sda1 start: 63
Disk SYSTEM(boot) ref: 7.4GiB type: USB [FORTINET 03_V012210_008] dev: /dev/sdb <- This partition is used for boot files.
partition ref: 247.0MiB, 199.0MiB free mounted: N label: dev: /dev/sdb1(boot) start: 0
partition ref: 247.0MiB, 186.0MiB free mounted: Y label: dev: /dev/sdb2(boot) start: 0
partition ref: 19 6.8GiB, 6.8GiB free mounted: Y label: dev: /dev/sdb3 start: 0
execute disk format <partition/device reference number(s)> <- Example ref: 255.
Note: This will reboot the FortiGate and rebuild the file system on the SDA partition.
Note: Remember to backup the data partition if there are logs that need to be kept. Refer to Technical Tip: Standard procedure to format a Fort... - Fortinet Community for log backup steps.
