Hey there,
for spindown- and performance-reasons, I´d like to move my jails to the system dataset.
I got a NAS-System consisting of a (high write endurance) SSD with 250Gb, that I planned to use as system disk and for my jails.
FreeNAS is installed to this SSD and uses 1,14GB of this SSD (what a waste of space)
The persistant data is held on four low speed 2,5" 1TB Harddisks, that show very weak performance .
For testing and easy of use, I gave the default setup a try and placed the jails on the data zvol - the performance is terrible (zoneminder, plex etc.) :-(
So for me it would fit perfectly if I´d move my jails to the 250 GB SSD, that holds boot and system zpool "freenas-boot" and
mirroring it on a regular basis to the data zvol (can I do it via a FreeNAS replication mechanism, or do I have to replicate it manually
via zfs send | zfs receive?).
Unfortunately (for good reason in "normal" setups) I can´t use the zpool "freenas-boot" for data storage via FreeNAS Web as zvols don´t show up in the gui.
I´ve already tried, creating a zfs volume via console and setting the mountpoint to /mnt/zroot-jail. Then I tried moving the jails
by changing "Jail Root" to "/mnt/zroot-jail" via web. FreeNAS denies that with reason "Jail root must be on a volume or dataset!"
Has anyone done this before or has an idea, how to achieve what I´m planning?
Thanks and kind regards,
Jakob
