Hello all,
I recently build my first homeserver and want to setup truenas.
Specs:
asrock b560m-itx/ac
i3 10100
32 GB RAM
Delock 5 port SATA PCI Express x4 Card
4x WD Red Plus 4 TB
+ SSDs for proxmox and backup of VMs
Truenas as VM
I'm currently following this guide https://www.truenas.com/community/resources/hard-drive-burn-in-testing.92/ for initial burn in. First drive exited with not output (last time I checked 0/0/0 erros). I'm running a smart long again and wait for the other drives to finish.
Somewhere I read, that not all drives are the same in size and can be helpful to leave some 200 mb free on the and hence partition them, in case you need to replace a drive and the new drive is slightly smaller for whatever reason. Can't find the link to it again though.
So probably tomorrow all drives should have finished badblocks and the smart long afterwards and I can begin to setup my system.
I tried determining what setup is best for but I'm unsure what's right for me. My requirements or non-requirements are:
Here a mirrored vdev is preferred https://jrs-s.net/2015/02/06/zfs-you-should-use-mirror-vdevs-not-raidz/ this thread (https://www.truenas.com/community/threads/which-raidz2-or-mirror.23401/) prefers raidz2.
Raidz2 has the advantage that any 2 drives can fail, with mirrored vdev I only have a 66.6 % chance to get lucky. However expansion should be easier with a mirrored vdev, which I don't think will be planned during the lifespan of the current HHDs anyway.
Any thing else I need to consider for my setup?
Any recommendations for mirror vs raidz2?
Thanks in advance!

I tried determining what setup is best for but I'm unsure what's right for me. My requirements or non-requirements are:
- NAS should act as local working directory for me and my wife.
- we rarely access the pool at the same time due to different working schedules
- connection is 1 Gbit anyway, so max. 100 mb/s
- availability is not a concern, if a drive failes we can afford to shutdown the server and wait for the replacement to arrive and be burned it
- we would mirror the data to each of our office PCs, specifically I have 2x4 tb in my PC (so I would mirror the whole NAS to my PC) and my wife would mirror her data to her internal 1 tb HDD additionally
- my PC is mirrored to backblaze personal backup
- performance is not a concern
- if I buy a nvme SSD I could use max. 6 HHDs in the future, however:
- 8 Tb of usable space is probably more than enough for the next 5 years
- I purchased 2 drives each from different vendors to get different batches
