I got 4 20TB drives from Amazon around Black Friday that I want to get setup for network storage. I’ve got 3 descent Ryzen 5000 series desktops that I was thinking about setting up so that I could build my own mini-Kubernetes cluster, but I don’t know if I have enough motivation. I’m pretty OCD so small projects often turn into big projects.
I don’t have an ECC motherboard though, so I want to get some input if BTRFS, ZFS, TrueNAS, or some other solution should be relatively safe without it? I guess it is a risk-factor but I haven’t had any issues yet (fingers crossed). I’ve been out of the CNCF space for a while but Rook used to be the way to go for Ceph on Kubernetes. Has there been any new projects worth checking out or should I just do RAID and get it over with? Does Ceph offer the same level of redundancy or performance? The boards have a single M.2 slot so I could add in some SSD caching.
If I go with RAID, should I do RAID 5 or 6? I’m also a bit worried because the drives are all the same so if there is an issue it could hit multiple drives at once, but I plan to try to have an online backup somewhere and if I order more drives I’ll balance it out with a different manufacturer.
I’d also suggest consider future expansion.
If you use RAID, what are you using to make your array? If it’s software, then it can easily move the array to some other box in the future if you run out of ports. If it’s hardware, does that manufacturer make a larger card and/or is it still supported? Etc.
Just give yourself room to grow.
Thanks… If I use RAID, then I’ll go with software RAID. Battery backup would be nice but maybe I can just get by with some UPS units.
