Hi,
I am unable to get any reads out of Newstore. The log is filled with
assert failures.

I've mostly been focused on write performance. Reads used to work, but
it's possible something broke recently. I'll try to reproduce.

Hi Neo,
The newstore::fie_map isn't implemented yet, so CEPH_OSD_OP_SPARSE_READ will get an assert(0). I will try to make it done today:)

I think you may need to disable sparse op in client side. NewStore
doesn't support fiemap interface now.

Hmm, I looked at rbd configs that doesn't support disable sprase read.
So It looks like we can't do rbd read for NewStore now.
