Re: FG1500D Disk Partitions and HA
We basically checked all these options in the KB. But those are to check the conditions/status but not to fix the partition mismatches. FTNT TAC recommended to run "exe formatlogdisk" on both units. It would probably re-partitioin it back to match 5.6's.
We got a maintenance window for another attempt to upgrade it to 6.0.5 next week. So I'll run this command on the slave then swap them over and run it on the other unit at the beginning of the window. Regardress if this fixes the mismatch or not, I'm planning to upgrade the cluster to 6.0 after making sure the slave at that time has 5.6 partitioning. When it starts upgrading, it upgrades the slave first so at that time the slave will run re-partitioning to match 6.0's. Then after that, they should see matching each other.
I'll update with the outcome next week.
