Proxmox 6.1 crushtool not working

[Haider Jarral]

Hello experts,

I am in process of setting a brand new cluster with 6.1, I am not able to compile the crushmap, the output file just does not show up, wondering if anyone else has seen it and whats the workaround

mhmm works here... what did you change in the crushmap.txt ? (i assume you wanted to manually edit it)

yes, I only added 2 classes one for hdd and one for ssd.

i guess the output is empty because there is no actual entry in the crushmap (no osd)
