Not sure if this is better fit for datahoarder or some selfhost community, but putting my money on this one.

The problem

I currently have a cute little server with two drives connected to it running a few different services (mostly media serving and torrents). The key facts here is that 1) it’s cute and little, 2) it’s handling pretty bulky data. Cute and little doesn’t go very well with big raid setups and such, and apart from upgrading one of the drives I’m probably at my limit in terms of how much storage I can physically fit in the machine. Also if I want to reinstall it or something that’s very difficult to do without downtime since I’d have to move the drive and services of to a different machine (not a huge problem since I’m the only one using it, but I don’t like it).

Solution

A distributed FS would definitely solve the issue of physically fitting more drives into the chassi, since I could basically just connect drives to a raspberry pi and have this raspi join the distributed fs. Great.

I think it could also solve the issue of potential downtime if I reinstall or do maintenance, since I can have multiple services read of the same distributed FS and reroute my reverse proxy to use the new services while the old ones are taken offline. There will potentially be a disruption, but no downtime.

Candidates

I know there are many different solutions for distributed filesystems, such as ceph, moosefs, glusterfs and miniio. I’m kinda leaning towards ceph because of it’s integration in proxmox, but it also seems like the most complicated solution in the bunch. Is it worth it? What are your experiences with these, and given the above description of my use-case which do you think would be the best fit?

Since I already have a lot of data it’s a bonus if it’s easy to migrate from my current filesystem somehow.

My current setup uses a lot of hard links as well, so it’s a big bonus if the solution has something similar (i.e. some easy way of storing the same data in multiple places without duplicating it)

    So you don’t know unraid has ZFS now then? Gotta keep up with the times.

    And it’s worth every cent as commercial software. I bought 2 pro licenses because it’s just that good.

      Sorta… If the array was built with hybrid ZFS within unraid which is what the majority of unraid users go with as it allows for better mixing of various sized drives and easier expansion of the array in the future (in other words the main selling points of unraid) then you do not get any of the safety nets ZFS provides as what unraid is essentially doing is making a single drive zfs vdev for each drive in the array. In unraid’s own words “ZFS-formatted disks in Unraid’s array do not offer inherent self-healing protection.”.

        Unraid natively supports full ZFS arrays in addition to unraid arrays since the last major release. Can mix and match both types on the same system as necessary.

        All of my (easily replaceable) Plex media is native unraid arrays while my documents are all on a ZFS array on the same system with snapshots and such. It’s the perfect solution.
