Increase OSD ram limit to whatever fits the hosts
Closed, ResolvedPublic


We increased the ram already to 8GB, but even then there's ~50% of the ram
unused on the machines. This task is to increase to 12GB that will bump that
usage up to ~75%, a more reasonable number.

Mentioned in SAL (#wikimedia-cloud) [2021-02-04T10:12:06Z] <dcaro> Increasing the memory limit of osds in eqiad from 8589934592(8G) to 12884901888(12G) (T273851)

It turns out that we have two sets of machines, each with different RAM specs.
The smaller machines have 64G, the bigger ones 124G.

I have changed the OSD memory limit to 6G (8G would use all the RAM, so I used
something that would leave a bit unused).
