As someone who's in charge of close to an exabyte on Ceph, I couldn't disagree with you more.

Done correctly, Ceph is extremely reliable, resilient, and fast. Once you get over the initial learning curve, dare I say, even a joy to work with.

For parallel read/write access across many thousands of large-ish files (ie multiples of the minimum chunk size) I'm sure it does grand.

But for metadata heavy operations, ie git, its not the FS I would choose. like lustre it can be fast, if your workload aligns with it's tradeoffs. but high metadata loads are not ceph-fs's strong point, (or many other distributed filesystems either)

I concur, even though I have only used it as a hobbyist.
