We have hit the following issues:
- Filestore merge splits occur at ~40 MObjects with default settings.
This is a really, really bad couple of days while things settle.
Could you elaborate on that?
As in which settings affect this and what happens exactly as "merge splits"
sounds like an oxymoron, so I suppose it's more of a split than a merge to
be so painful?
Filestore merges directories when the leafs are largely empty and splits
when they're full. So they're sort of the same thing. Here's the
result of a test I ran storing objects into RGW as fast as possible and
you can see performance tank while directories split and recover afterwards.
