Cannot create Vdevs

[SmallBarky]

OP has other posts. It’s a new mini + with 5 HD and 2 SSD. Guessing drives assigned to previous pool

Help with setup please

I’ve just received my xi min + system and I’ve create a pool but that as far as I’ve gotten. I’ve read for 3 weeks the posts and am totally confused on how tom set this thing up for plex and to get my movies and other media on it. Can some one hold my hand and walk me through the se3tup process. The system is as follows, xi mini + with 64 gigs of ram, 5 14 tb hard drives and two 450 ssd’s, thank you for the help
