Description
This article describes the commands used to check cluster checksums and recalculate the checksum, which were changed from v5.4.0 onwards.
Scope
FortiOS.
Solution
In FortiOS v5.0 and v5.2, the command for checking the checksum was:
# diagnose sys ha cluster-csum
InFortiOS v5.0 and v5.2, the command for recalculating the checksum was:
# diagnose sys ha csum-recalculate
In FortiOS v5.4 and above, the command for checking the checksum is:
# diagnose sys ha checksum cluster
In FortiOS v5.4 and above, the command for recalculating the checksum is:
# diagnose sys ha checksum recalculate
Additionally, specific VDOMs can be individually recalculated in FortiOS v5.4 and above. This is useful if they are not in sync.
Run the following command on ALL cluster devices:
# diagnose sys ha checksum recalculate <VDOM>
For example:
# diagnose sys ha checksum recalculate root
