Dan, sorry, we have no gaps in osd numbering: isceph@ceph-deploy:~$ sudo ceph osd ls |wc -l; sudo ceph osd tree | sort -n -k1 |tail 76 [..] 73 ssd 0.28600 osd.73 up 1.00000 1.00000 74 ssd 0.27689 osd.74 up 1.00000 1.00000 75 ssd 0.28600 osd.75 up 1.00000 1.00000 The (quite old) cluster is running v15.2.13 very well. :-) OSDs running on top of (newest) centos8.4 bare metal, mon/mds run on (bewest) Centos 7.9 VMs. Problem just appears only with the newest Centos8 client libceph.
