Hi,
Thanks so far for the suggestions.
We have enabled the balancer first to make sure PG distribution is more
optimal. After a few additions/replacements and data growth it was not optimal.
We enabled upmap as this was suggested to be better than the default setting.

Hi,
last weekend we upgraded one of our clusters from 16.2.5 to 16.2.7 using
cephadm.
The upgrade itself seemed to run without a problem but shortly after the

Good afternoon, thank you for your reply. Yes I know you are right,
eventually we'll switch to an odd number of mons rather than even. We're

have just 1 PG.
