So I recently found out that I have sh*t my leg… I was about to set up unraid but just before dipping my toes I was told that the parity drive needs to be the same or larger in size, really wish I had done more thorough reseach before recently buying that 10TB HDD hehe…

My planned setup was; 250 GB - SSD (Cache) 1 TB - HDD (Parity) 2 TB - HDD (Pool) 10 TB - HDD (Pool)

So what are my option now that I have messed that up, what would you recommend? To go without parity or is there another way?

Any help is appriciated, I am still quite new to selfhosting/linux :)

UPDATE; I can trade the 10TB for two 4TB disks + the extra. Should I?

    If it was me, I’d just go without parity temporarily and grab another drive for that when I could. A new system should be safe enough for a while, just not forever.

      Yeah I think this is the “best” for me right now unfortunately… But even buying a new 10TB disk ‘just’ for backup is kind of unfortunate… I might try to sell it or trade it for multiple other disks.

        Gohardrive has those 10tb for under $90, they’ve been used for like 5 years but if it’s non essential data they should last a long time and might be a good option.

    250GB cache

    1 TB Pool

    2 TB Pool

    (2TB Parity partition + 8TB non-redundant storage partition) = 10 TB HDD

    You’ll have a total of 3 TB that’s protected, and 8 TB that’s not. When you get another 10 TB drive in the future, then you’ll have a total of 13 TB that’s protected.

    How I’d go above this is dependent on how much storage you expect to be using mid term/until you want/can buy another drive.

    Must have 7TB ? Swap the 10tb for 2x4TB, then do 4TB parity 4+2+1TB as Data drives.

    Is 3TB enough for the time being? Keep the 10TB and use as parity, 1+2TB as Data drives. When full, go for up to another 10TB as Data.

    That second option is more upgradable in the future.

    I’m guessing everyone meant Data drives by saying “pool”. In unraid, Data drives are the ones protected by parity, in the array. Pools are “out of the array”, not protected by parity.

      Thanks for this! I actually just found yet another 2TB HDD that I had forgotten about, so I might just go for what you said! Leaves me with 5TB for now and 10TB for the parity.

    Now your next drive can be 10TB! Not a mistake, you were just unintentionally future proofing

    250GB - cache
    1TB - Pool
    2TB - Pool
    10TB - Parity

    With only 3TB in the pool you’re going to be increasing the size of the pool potentially quite quickly depending on if you’re ripping DVDs or Blu-Rays to it.

    You’ll soon need another drive to boost that pool size and I promise, that parity will keep those tears at bay if something happens.
