I personally think of a small DIY rack stuffed with commodity HDDs off Ebay with an LVM spanned across a bunch of RAID1s. I don’t want any complex architectural solutions since my homelab’s scale always equals 1. To my current understanding this has little to no obvious drawbacks. What do you think?
Just btrfs.
Why btrfs and not ZFS? In my info bubble, the btrfs has a reputation of an unstable FS and people ended up with unrecoverable data.
