Questions around disk space and parity in unraid

Mr. Forager@lemmy.world to Selfhosted@lemmy.world – 17 points –

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?

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.

Didn't know this was possible, can I do the partitioning via unraid gui? How risky is it to do it this way?

Like they said, the 2 GB partition would be covered by parity and can be recovered, the 8 GB cannot.
