Hello,

I'm looking for a file system that can be mounted on a Linux client and
that is being distributed among multiple servers like a RAID 0. However,
I'd like it to have file system snapshots and the possibility to grow by
adding additional servers. I know BeeGFS, but it's lacking the
snapshots. I know ZFS, but it's lacking the ability to be spread across
multiple servers.
Can you recommend somthing combining those two? It does not need to be
free of charge, but it needs to work reliably.

BTRFS has RAID and snapshots. Not sure about the server part.
