fortimail external storage

[bonfigli]

Hi all,

we use a fortimail cluster for just antispam services, we want to use an external storage so that the quarantine is stored in an external NAS.

question: what happen if the NAS is unavailable / broken? Do the emails flow regularly, only the quarantine are not stored, or the antispam services block completely?

Relating issue: currently we use active-passive HA with two units on the same subnets, local storage, everything works good. Because of organization rearrangement, to improve redundancy we want to move a unit in another office branch (both the offices are connected each other via a site to site vpn), so that this unit will live in a different subnet, both the units will be active, mail service redundancy will be achieved via DNS mx records, we don't mind to redound the http service (there will be two dns A records pointing to the web interface, for example antispam.myorg.org and antispam-bk.mayorg.org) . To do that we must switch to config-only HA with NAS external storage. The two units must point to the same nfs partition on this NAS as I understand. Is this right? If a unit is master and experience a failure, can I promote the other one to master without corrupting the data? what happen if a unit cannot reach the nas for a period when the other unit can (for example when the vpn between the two office fails), and then it works again, will the data in the NAS be corrupted?
