Hi Dev, osd_skip_check_past_interval_bounds was introduced in Reef v18.2.5 to allow crashing OSDs to start [1][2]. This setting never made it to Squid as the original bug leading to crashing OSDs [3] was fixed prior to any Squid releases. Anyone running any major or minor version of Ceph above 18.2.5+ should remove this setting. Regards, Frédéric.

The command 'ceph osd find <ID>' is not the right one to query an OSD for the cluster network, it just shows the public address of an OSD (like a client would need to). Just use 'ceph osd dump' and look at the OSD output.
Zitat von Devender Singh <devender@netskrt.io>:
Hello
I checked on my all clusters everywhere OSD’s not using cluster network. Here is another example in my lab where I have three hosts in vlan1 and vlan2 running on one proxmox server and here also same thing… No MTU change, these are default to 1500.
I don’t understand what I am missing?
