SOLVED Drive backup using mirroring: how to restore? Hello! My setup is the following: 1 vdev with 3 HDDs, all 3 mirror of each other (so 3 x 3TB HDD, total available space = 3TB) 2 Drives are just going to spin all the time, mirror of each other, that's the redundancy The 3rd drive, I'll plug it in once every now and then (say: once per
- 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
- 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

- Some differences between RAIDZ and mirrors, and why we use . . . - TrueNAS

- 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
- Reword pool Extend to Attach a Mirror to be consistent . . . - TrueNAS
It may not be deliberate, but we do plan to support RAIDZ expansion in 2024 in this case adding a drive to a VDEV is an "extension" Makes even more sense to distinguish the 2 features! Make the "Extend" button actually extend a RAIDZ pool and a separate "Attach" button attach a mirror, as per under the hood CLI terminology
