Hi,
I am reading and preparing to step to FreeNAS since a few months now.
Storage specs:
- 7 spare bays. I plan to use 6 for the pools and keep one spare for maintenance and easy increase of pool disk size if needed.
- Disk sizes will range from 4 TB to 16 TB
Basically, I am hesitating between these 2 approaches:
1- One pool with 6 drives in z2
vs
2- Three distinct pools in Mirror mode
I don't care loosing space with option 2 and I priorise security + fast rebuilds when recovering from a degraded pool.
I read in one of the pinned pdf/powepoint docs that Mirror is not recommended with large capacity disks, but no explanation.
Option 2 is really the way I thought to go because of 2 main aspects:
- less risk to loose all the pool data on a failure/error, that is the whole 4 (+2 recovery) disks data
- faster recovery from a degraded pool
Is this really a bad choice because of the disks capacity or something I am missing ?
Thank you and best regards
