February 23, 20206 yr I've ordered parts, and waiting for them to come in to build my first UnRAID server! A couple of questions... I'm going to start with 2 new drives (I've already purchased them and ran Pre-Clear on them), set one up as parity and the other one as a drive. I'll take one of my current data drives on my desktop (starting with Plex TV Shows), move them to the UnRAID drive. Once it's emptied, I'll pre-clear it and install it as a 2nd drive. I will continue to empty drives, adding them as data drives in the array. I'm also going to have 2 120GB SSD drives as a cache, mirrored. Question 1: Does it make sense to hold off on the cache drive until AFTER I move all the data from the old drives and get the array set up? Is there a down side to it? Question 2: If I set a share as High Water with a single drive, move a bunch of files to it, then install a 2nd drive, does it immediately move half of the files over, or will it start writing files to the second drive when I have new files to write? Thanks, guys!
