Although you can use any of the redundancy levels, RAIDZ2 is perhaps your best option when setting up a home or office network storage system. The RAIDZ2 requires at least four drives, and despite the usable storage will be reduced by the number of two drives, you can have up to two drive failures without losing your files. In comparison, Stripe requires at least one drive, and it’s more suited for performance, but if you lose one of the drives, you’ll lose all your data. Mirror requires at least two drives, and whatever you copy on one of the drives, it’ll automatically replicate to the second drive, which losing either of the drives won’t cause data loss. The RAIDZ1 requires at least three drives, but if you lose a second drive during rebuild or while you’re ordering a replacement, you’ll lose all your data. Finally, RAIDZ3 requires at least five disks, and it’s similar to RAIDZ2, with the exception that up to three disks can fail before you lose your data. In this guide, you’ll learn the steps to create a RAIDZ2 storage pool to provide good redundancy and performance balance your FreeNAS server (version 11.2 and higher).
How to create RAIDZ2 storage pool using FreeNAS
To create a RAIDZ2 pool on FreeNAS, use these steps: Once you complete the steps, the FreeNAS RAIDZ2 pool will be created, and you can now proceed to create a dataset that will host folders that you want to share in the network.
