HOW TO: 2.4.0 ZFS Install, RAM Disk, Hot Spare, Snapshot, Resilver Root Drive

[kpa]

What the hell you need a separate ZIL device *) for on a firewall system? It makes sense on a very busy file server but a firewall system is mostly just idling on the disk I/O side.

*) The ZIL log is "ZFS intent log", used only for guaranteeing integrity and atomicity of synchronous writes on ZFS in case the system crashes.

Given the Low Specs on an SG-1000 (RAM particularly) I imagine ZFS is a bad idea?

[ivor]

Correct, we do not support or recommend running ZFS on SG-1000.

this topic is old but I think with fresh 2.4.4 installs there will be more if not all users doing ZFS and should be doing a mirror or 3way mirror. That leads to the question about the GUI interface to manage ZFS. Would it be easier for pfSense just to make a plugin for FreeNAS so the firewall can run as a IOCage jail? The IOCage jail could have 2 NIC's passed to it and now the FreeNAS would manage the ZFS complexity.

On a side note the pfSense jail would be able to reboot in 1 second. :-)

The other cool idea would be to have two pfSense IOCage jails so that you could run them in HA, patch and upgrade the secondary while the primary keeps running. I am doing this today with VMware ESXI but because pfSense is a VM it does not boot in 1 second like a jail...

Can anyone tell me why I'm not seeing an option for ZFS?
Installing 2.3.5 cd-rom platform. I'm not getting the "welcome" screen. It goes right to select video, then to quick/easy install/custom install. If I select custom, there's no ZFS option.
What am I missing?

[chrismacmahon]

ZFS is an available option in 2.4.0 and above.

[Jarhead]

A ha . That makes sense.
Thanks

So is there still no "official" way to have all files in the disk to be included with the 2-copies scheme of set (when "zfs set copies=2 zroot" is set) after installation? I can't find anything in the Internet that answers this.

@kevindd992002 did you ever find an answer to this? I want to rebuild my system with zfs for more robustness and copies=2 would be some nice additional protection on my single SSD system.

Not really. No one from this thread seems to want to talk about this further :(
