[ceph-users] OSD out/down detection

Hi All, We have a Jewel (10.2.1) cluster on Centos 7 - I am using an elrepo 4.4.1 kernel on all machines and we have an issue where some of the machines hang - not sure if its hardware or OS but essentially the host including the console is unresponsive and can only be recovered with a

Re: [ceph-users] Wrong Content-Range for zero size object
