- Mirroring the Boot Pool | TrueNAS Documentation Hub
Adding a second storage device to the boot pool changes the configuration to a Mirror This allows one of the devices to fail and the system still boots If one of the two devices were to fail, that device is easily detached and replaced When adding a second device to create a mirrored boot pool, consider these caveats: Capacity: The new device must have at least the same capacity as the
- 3 Drive Configuration | TrueNAS Community
The drive prices for 16TB drives (specifically Exos) are pretty decent compared to 10TB I think, thus why I want 16TB Are there any downsides to a 3 way mirror? Would it allow two out of the three drives fail without incident? Also if you know any documentation on it that would help a lot Also with RAIDZ, adding drives to a pool later requires resilvering, does a mirror 3 way mirror require

- SOLVED - Help understanding Mirrored vdevs in relation to pools
12 disks in 6 mirror vdevs give you the IOPS of 6 disks At the expense of less resiliency - one disk is easy peasy, lose two disks and you might still be ok, but as soon as you lose an entire vdev, the pool is toast So your assumption about the right three disks failing is correct
- Cannot add a mirrored drive to an existing single disk pool
No, you don't want to add a vDev This is how to attach a Mirror device, (though we are requesting the wording to be clearer); Go to "Storage" Under "Topology", select "Manage Devices" Select the stripe with your single disk, (but don't select the current disk) You should now have an "Extend" option to the right, select it Now select your new disk, and press the "Extend" button It should now
- SOLVED - Best disk configuration (RAID) for 4 HD x 4TB each (TrueNAS . . .
With 4 drives, unless you want a 4-way mirror, the best configuration is a RAIDZ2 VDEV composed of all the 4 drives since it gives you better resiliency than 2 VDEVS in a 2-way mirror configuration each
- Performance: RAIDz1 vs mirroring | TrueNAS Community
For a personal computer (Unix) I have to decide between mirroring 2 SSDs or RAIDz1 3 SSDs After some reading, I found places that say mirroring is faster than RAIDz1 This doesn't make any sense to me Yes, RAIDz1 has to compute the parity info for the third disk But, CPU times (for
