Pfsense on a gmirror pair?
I've been dabbling with other firewall distros, but I think I finally found a use-case I can't implement with any other distro (that I know of, anyway…) I have two ESXi hosts in a HA cluster. I am not really worried about zero downtime, so if the production host fails, the VMs will all be restarted on the other host. Because I don't want any to take down the internet (even briefly), I was playing with the firewall VM being FT rather than HA. Here's the single point of failure though: Both HA and FT require the VMs to be on shared storage. I have a NAS/SAN using ZFS and sharing to ESXi with NFS. The problem is that if the NAS/SAN server fails, the FT VM fails too. So my idea: install pfsense on a gmirror pair. One disk is on the production NAS/SAN host, the other is on a backup (low-use) NAS. So if the NAS/SAN fails, pfsense should keep running, correct?
I haven't used it, but I've noticed that "Install on gmirror" or similarly worded option appears in the installer if 2 or more disks are available. So you should be able to add 2 or more virtual drives for the VM and setup a gmirror during the setup.
