RAID

Most FortiGate devices with multiple disk drives (SSD or HHD) can be configured to use RAID.

Caution

Enabling or disabling RAID, and changing the RAID level, erases all data on the log disk and reboots the device.
To verify that the FortiGate has multiple disks:

  • List disk devices and partitions:

    # execute disk list

Disk SSD1 ref: 255 223.6GiB type: SSD [ATA INTEL SSDSC2KB24] dev: /dev/sda
  partition ref: 1 220.1GiB, 219.0GiB free mounted: Y label: LOGUSEDXA707476A dev: /dev/sda1 start: 2048

Disk SSD2 ref: 16 223.6GiB type: SSD [ATA INTEL SSDSC2KB24] dev: /dev/sdb
  partition ref: 17 62.7GiB, 62.4GiB free mounted: Y label: WANOPTXX1FEBBFA1 dev: /dev/sdb1 start: 2048
  partition ref: 18 63.7GiB, 63.7GiB free mounted: N label: dev: /dev/sdb2 start: 133625856
  partition ref: 19 85.0GiB, 85.0GiB free mounted: N label: dev: /dev/sdb3 start: 267249664

  • Display information about all of the disks:
