I apologize if this question has been answered before. I searched "mixed disk" in the search and didn't see any results.
I currently have a mixture of disks I would like to use in my ZFS setup. I would like some redundancy (be able to lose at least 1 drive) so I believe a raidz setup is ideal, but the mixture of disks is unusual. Can someone suggest some pointers on optimizing my setup?
Here's my disk mixture:
1x 240 GB SSD
1x 4 TB 7200
3x 2 TB 5400 (very slow "green" drives)
How would you suggest I organize my ZFS pools to optimize storage, speed, and redundancy?
Currently I have two pools and the SSD split into separate cache volumes:
OS installed to 4 TB disk
3x 2 TB disk used in a raidz mounted separately
SSD split into two logical volumes and added as a cache to both the OS and the disks.
My problem is there's no redundancy with the OS and I'm not sure about the SSD split. Would it be better to create a 150 GB partition on both the SSD and 4 TB disk, then install the OS in a raidz setup for this pool? Then I could create the raidz with the 3x 2 TB disks. I could use the remaining 70 GB ssd space as a cache for the raidz?
Thank you all in advance for this setup. Please feel free to point out anything wrong in my setup. Your help is greatly appreciated!
