@GUIn00b said in ProxMox Storage Configuration Question (idk how lol):
Quick update: I did this https://help.nodespace.com/knowledgebase.php?article=307 to all 4 drives, then created a 7.0 TB lvm-thin. Is that the right way to go about this? Here's console output:

That looks correct to me. Convincing ProxMox to use it as an lvm-thin pool might be a bit tricky as it wants a blank block device in the gui....
ProxMox's aversion to the best RAID system available is mind blowing to me. They've completely bought into the cult of ZFS and the Windows world of "software RAID is bad".
