Hi, We want to upgrade the OS version of our production ceph cluster by reinstalling the OS on the server. Is there any way to upgrade the OS without having to redeploy the OSDs? We looked at the contents of /var/lib/ceph/osd/ceph-*, the block directory is linked to a lvm device. If we reinstall the OS, will there be any problem with this linked directory?
