November 19, 2025Nov 19 Author Hi(I do greet other ppl online - I read that you do not)I read the doc and I did the same thing as in the video. (Been there, done that), i understand, that z1 is a R5 alike?Is there no info on paritiy or a parity check function?br Edited November 19, 2025Nov 19 by simu

For instance trying "zfs where is parity held" shows that it is striped across drives, and that there is no direct equivalent to the Unraid Parity Check functionalit as that is handled automatiall as a background activity..
