Hey guys, I’m setting up my NAS (openmediavault) and very much enjoying it! It now runs my Nextcloud and a couple of services. I got a mirror ZFS setup of two 8TB drives.
I got another two 8TB drives and am doubting whether I should add them as an extra mirror vdev, or create a new pool for extra backup. I’m not sure if that extra backup is necessary though, since I got a cloud backup already every day. My drives are only used 14% so I’m not even sure if I should already put them in the pool. What do you guys think?
Raid5 of three disks and keep the fourth as cold spare. That’s 16TB instead of 24, but you’re barely using your current 8, so a spare makes more sense.
Hmm I think RAID5 would be risky. If I have a 16TB array and then get a failure, resilvering would take long and that could bring a second disk down…
