I clustered five raspberry PIs using Ceph. It's not super great performing, but currently getting 30MBps reads and writes for different pool types; most notably 3 times replicated and 3+2 erasure coded one. There are 6 Adata HD720 2.5" 2TB USB spinning drives. Planning to add SSD for Journaling and wal now.
I've put that cluster through hell - like pulling one straight out and resoldered one USB PSU pass through mod and it didn't lose data at all.

I'm mightily impressed that it works at all
