Hi David,
Thank you for the reply. Unfortunately, the health detail only shows
blocked requests. This seems to be related to a compression setting
on the pool, nothing in OSD logs.
I replied to another compression thread. This makes sense since
compression is new, and in the past all such issues were reflected in
OSD logs and related to either network or OSD hardware.
Regards,
Alex
