Clarification on Ceph "MAX AVAIL" Calculation for RHCS 5

Hello,

I am currently facing an issue calculating the ceph df  "MAX AVAIL" for Ceph in our cluster. While I found the article Solution 2273951 , it only covers versions RHCS 1.3, 2, and 3. We are using RHCS 5, and it appears that the formula mentioned in the document:

min(osd.avail for osd in OSD_up) * len(osd.avail for osd in OSD_up) / pool.size()

is not applicable or does not yield accurate results in our case.

Could you provide guidance or documentation specific to RHCS 5 on how to correctly calculate the ceph df  "MAX AVAIL"? If there's a new formula for this version, I would greatly appreciate it.
