First build. In need of advice.

Hi,

I got my hands on a disused CPU (i3 8350k) with motherboard and PSU. I am currently running an old NUC as a server, which hosts my Nextcloud instance and couple other services. The thing is, I ran out of space on that little SSD.

Anyway, as I got a good deal on 32 GB of DDR4 RAM, I thought, that I’d build a new server. I will most likely be running Ubuntu Server on it (it will run Docker with Nextcloud, etc. and act also as a NAS).

I have 2 6 TB WD Reds from current NAS and I will be adding 2 others.

My question is, which drive config would be the best? I was interested in using ZFS, but from the info I’ve read, it seems like a bad option to go with RAID-Z1.

I’ll be grateful for any advice.

  1. If you have 2x6TB drives and will be adding 2 others (of the same size or higher) then create a pool of mirrors.

    ‘ zpool create zpoolname mirror sdb sdc mirror sdd sde ‘

    ​

    / substitute drive designations as appropriate and DO NOT use **-f** flag (force) unless you really know what you’re doing

    // if the drives already have data / partition table on them you should use

    ‘ **wipefs -a** ‘ to clear them before using them to create a zfs pool

    ​

    After the pool is created with the short drive letters, you can **zpool export** it and use ‘ **zpool import -a -d /dev/disk/by-id** ‘ to get it using the long drive paths.

  2. With 3 drives RAID-Z1 is the best choice. For RAID-Z2 I would take more drives.

    Z1 is not bad, you just have a lower level of redundancy. It is the same as RAID 5 vs RAID 6. Here are some Pros and Cons: [https://www.starwindsoftware.com/blog/back-to-basics-raid-types](https://www.starwindsoftware.com/blog/back-to-basics-raid-types).

    You need more drives or the 3-2-1 backup approach and more backup copies. Additionally: [https://www.diskinternals.com/raid-recovery/what-is-raidz/](https://www.diskinternals.com/raid-recovery/what-is-raidz/)

  3. RAID Z1 is fine especially with just a few disks, and 6TB aren’t huge drives either. Just have a solid backup.

    By WD Red, I hope you mean the Red Plus / non SMR drives. Because if you go with SMR and ZFS RAID you will be in a world of hurt with write performance.

  4. I would try to get 6-9 data drives and use RAIDz2:

    ​

    4 drives with any 2 drive failure tolerance, gives you just under 1/2 usable space

    6 drives with any 2 drive failure tolerance, give you just under 2/3rds usable space…

    8 drives with any 2 drive failure tolerance, give you just under 3/4ers usable space…

    ​

    With 2 mirrors, you can still lose data if the wrong 2 drives fail

    Just buy at a minimum 2 more 6TB drives, 5 more if you can (Almost all of each additional drive can be used, dropping cost per usable TB)

    How many times have you said “my new drive is so big I’ll never fill it up…”
