Description Kyle Bader 2022-08-25 17:50:38 UTC

Description of problem:

By default rgw_max_chunk_size is 4MB and rgw_obj_stripe_size is 4MB

rgw_max_chunk_size needs to be <= rgw_obj_stripe_size

If it's not, and a client makes a PutObject call > rgw_obj_stripe_size, then it will fail (closes connection IIRC).

RHCS 5.1

How reproducible:

Easy, see above.

Steps to Reproduce:
1. Wet rgw_max_chunk_size to 16MB
2. Restart RGWs
3. PutObject > 4MB

Actual results:

Exception, connection closed.

Expected results:

RGW log a warning on startup and set rgw_max_chunk_size = rgw_obj_stripe_size if rgw_max_chunk_size > rgw_obj_stripe_size.
