There are lots of other options too like LizardFS: https://lizardfs.com https://lizardfs.com Seems really nice and easy to deploy.

But Ceph seems to be supported in everything. I know it's supported in Ganeti, which I currently run (and love) and Proxmox (which I used to run).

  LizardFS/MooseFS is mounted as regular filesystem (it behaves like NFS) so I would imagine everything should work with it.

    Everything does not work with NFS, including things like file locking.

      NFS has lockd and MooseFS apparently also supports locking since version 3.0.

That one is derived from MooseFS (https://moosefs.com/ https://moosefs.com/). What turned me away from LizardFS was when they forked the project the very first thing they did was rewriting the code to be in C++, this makes much harder to merge future improvements, and feels like they make some decisions for the wrong reason (the user doesn't care what language it is written in) MooseFS is quite good and has fairly good performance, but its weakness is that is also that the central point is its master, and the open source version doesn't have HA. I know that LizardFS supposedly has HA (it didn't have it at the time I looked into it), how is that implemented?

  MooseFS can have a second master that takes over if the first one should fail, though.

    I'm familiar with 1.x which was very basic, glad they added that. The previous approach with metadataloggers had the issue that before you can convert it to a master you had to merge changelogs which could take a while when you have many files.

  what is the use case where one would want to implement either lizard/moose into prod? Why? What are you solving for with these?

    When evaluating various distributed filesystems MooseFS[1] was the fastest one. [1] I did not evaluate LizardFS but back then it was freshly forked so it was pretty much the same thing.

Have had very good experiances with MooseFS the predecessor to LizardFS, Rock steady never crashed or did something finicky. Performance was ok.
