then it does not seem it changes the # of parity drives at all (for a single vdev) but will provide increased performance for the same amount of drives. The question should be if larger vdevs (> 12 drives per vdev) are possible with draid and if a draid vdev still has the sing...
Despite the big efforts by TrueNAS to demystify the complexity of storage management in several areas of its storage area (fusion pools being partially automated mixed media pools, the suggested vDev drive drop-down, USB management in that same area and ‘force’ warning options to name but a...
So, even if you went with one RAIDz2 vdev and striped in the mirrrored vdev, your storage capacity would be the same as having 3 mirrored vdevs. The other issue is that we don't recommend mixing vdev types within a given pool. If you are using RAIDz2 in a pool with mulitple...
Both types of devices improve performance, and throughput can be impacted by their removal. 8.5.2. Replacing Disks to Grow a Pool The recommended method for expanding the size of a ZFS pool is to pre-plan the number of disks in a vdev and to stripe additional vdevs from Pools as ...
purchase order information, warranty end date, warranty URL, and any other useful information about each drive.Klararecommends embedding these details directly into the ZFS vdev properties of each disk—a feature Klara created, which will become generally available in the upcoming OpenZFS 2.2 release...
I have FreeNAS 11 running now on a 120GB SSD. The main purpose is for me to use ZFS (Raid2?) to make my setup expandable. I want to use all 8 drives for a single vdev and when it fills up, I want to be able to add 2 more vdevs with the same drive types and sizes in ...

to have in the pool. If the setup is simple you can even select Suggest Layout and that will take like sized disks and types and use them in the pool. We selected the 3 Seagate IronWolf hard drives for DATA and assigned the SSD to a VDEV for CACHE by selecting ADD VDEV – CACHE....
