So besides the obvious btrfs answer, what about ceph as clustered storage with very fast connectivity? There is also BeeGFS, I haven't used it but /r/datahoard

So besides the obvious btrfs answer, what about ceph as clustered storage with very fast connectivity? There is also BeeGFS, I haven't used it but /r/datahoarders sometimes touts it. Not for linux but I have been keeping an eye on M Dillons DragonFly BSD where he has been working on HAMMER2, which is very interesting. I don't know much but bcachefs has been making more waves lately also. I think the bottom line is that people need to have good backup in place regardless.
