so I'm running like 12 MDADM raid 5 arrays, grouped in a single VG0 > LV0 > BTRFS sits on top of this LVM

I just had a degraded drive fail on me... I don't have a spare drive to repair my Raid 5 arrays lmao and I want to reshape them uising grow but my frakinstein configuration is a pain to manage and I feel like I will break something
