HOW TO: 2.4.0 ZFS Install, RAM Disk, Hot Spare, Snapshot, Resilver Root Drive
-
I was thinking of creating a ZFS on a SSD 16GB and use another hard drive 320GB formatted UFS for data log collection. However, upon reading this: https://docs.oracle.com/cd/E19253-01/819-5461/gaynr/index.html it appears that won't work as stated there:
"The root pool cannot have a separate log device."
So, UFS it is…unless, someone can share more info. I have had a bad experience with one disk "raid"...it was a Cloudbox 3TB drive...died just over a year so no warranty...waste of money.

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?
-
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? -
ZFS is an available option in 2.4.0 and above.
-
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 :(
