Hello! I stuck with a problem, while trying to create cluster of 3 nodes (AWS EC2 instancies): fa11 ~ # ceph orch host ls HOST ADDR LABELS STATUS fa11 172.16.24.67 _admin fa12 172.16.23.159 _admin fa13 172.16.25.119 _admin 3 hosts in cluster Each of them have 2 disks (all accepted by CEPH): fa11 ~ # ceph orch device ls HOST PATH TYPE DEVICE ID SIZE AVAILABLE REFRESHED REJECT REASONS fa11 /dev/nvme1n1 ssd Amazon_Elastic_Block_Store_vol016651cf7f3b9c9dd 8589M Yes 7m ago fa11 /dev/nvme2n1 ssd Amazon_Elastic_Block_Store_vol034082d7d364dfbdb 5368M Yes 7m ago fa12 /dev/nvme1n1 ssd Amazon_Elastic_Block_Store_vol0ec193fa3f77fee66 8589M Yes 3m ago fa12 /dev/nvme2n1 ssd Amazon_Elastic_Block_Store_vol018736f7eeab725f5 5368M Yes 3m ago fa13 /dev/nvme1n1 ssd Amazon_Elastic_Block_Store_vol0443a031550be1024 8589M Yes 84s ago fa13 /dev/nvme2n1 ssd Amazon_Elastic_Block_Store_vol0870412d37717dc2c 5368M Yes 84s ago fa11 is first host, where from I manage cluster. Adding OSD from fa11 itself works fine: fa11 ~ # ceph orch daemon add osd fa11:/dev/nvme1n1 Created osd(s) 0 on host 'fa11' But it doesn't work for other 2 hosts (it hangs forever): fa11 ~ # ceph orch daemon add osd fa12:/dev/nvme1n1 ^CInterrupted Logs on fa12 shows that it hangs at following step: fa12 ~ # tail /var/log/ceph/a9ef6c26-ac38-11ed-9429-06e6bc29c1db/ceph-volume.log ...
