Hi,
Here is a snippet from top on a node with 10 OSDs.
===========================

MiB Swap: 128000.0 total, 126754.7 free, 1245.3 used. 221608.0 avail Mem

===========================
Does it look OK with 2GB free?
I can't tell how that 220GB is used for buffer/cache.
Is that used by OSDs? Is it controlled by configuration or auto scaling based
on physical memory? Any clarifications would be helpful.
Thanks!
Tony
