i currently have a server running omv, with a zfs pool with a 4tb and 2x 2tb, for a total of 8tb however there is no parity or backup so if a drive fails it all goes kaput.
which means replacing- i want to upgrade my storage and have a better solution for potential drive failures, while potentially being expandable in the future. most of my data is movies / tv / music that can be reacquired, critical data is small and is backed up.
my budget isn’t massive, i’ve only just started working full time, so have potentially been looking at 3x 8tb drives in a raid-z1 array, for 16tb useable. being able to add in another drive in the future would also be good, and i think raidz1 would allow this, but hopefully by that point i can just afford a completely new server.
is this a good plan? or would there be a better array i could do? any advice would be much appreciated, thanks
