Hi, After adding a node to the cluster (3 nodes) with cephadm, how do I add OSDs with the same configuration on the other nodes ? The other nodes have 12 drives for data osd-block AND 2 drives for wal osd-wal. There are 6 LVs in each wal disk for the 12 data drives. I have added the ODS with ceph orch daemon add osd hostname:/dev/nvme0n1 How do I attach the wal devices to the OSDs? I have the WAL volumes created nvme3n1 259:5 0 349.3G 0 disk |-ceph--75d65cd1--91e4--4a8f--869b--e2a550f83104-osd--wal--dad0df4e--149a--4e80--b451--79f9b81838b8 253:12 0 58.2G 0 lvm |-ceph--75d65cd1--91e4--4a8f--869b--e2a550f83104-osd--wal--a5f2e93a--7bf0--4904--a233--3946b855c764 253:13 0 58.2G 0 lvm |-ceph--75d65cd1--91e4--4a8f--869b--e2a550f83104-osd--wal--cc949e1b--2560--4d38--bc27--558550881726 253:14 0 58.2G 0 lvm |-ceph--75d65cd1--91e4--4a8f--869b--e2a550f83104-osd--wal--8846f50e--7e92--4f66--a738--ce3a89650019 253:15 0 58.2G 0 lvm |-ceph--75d65cd1--91e4--4a8f--869b--e2a550f83104-osd--wal--6d646762--483a--40ca--8c51--ea54e0684a94 253:16 0 58.2G 0 lvm `-ceph--75d65cd1--91e4--4a8f--869b--e2a550f83104-osd--wal--74e58163--de1d--4062--a658--5b0356d43a87 253:17 0 58.2G 0 lvm How do I attach the wal volumes to the OSDs osd.36 nvme0n1 259:1 0 5.8T 0 disk `-ceph--3df7c5c3--c2c0--4498--9e17--2af79e448abc-osd--block--804b50ea--d44c--4cad--9177--8d722f737df9 253:0 0 5.8T 0 lvm Osd.37 nvme1n1 259:3 0 5.8T 0 disk `-ceph--30858acc--c48b--4a08--bb98--4c9b59112c59-osd--block--0a3a198b--66ec--4ed9--94da--fb171e190e38 253:1 0 5.8T 0 lvm nvme3n1 Thank you, Anantha
