Subject: [PVE-User] Remove 1-2 OSD from PVE Cluster
Date: Thu, 13 Jan 2022 11:13:53 +0300	[thread overview]
Message-ID: <37cd7904-a225-76f6-7bd3-973a75be2c74@t8.ru> (raw)

Hello to all.

I have cluster with 7 node.

Storage for VM disk and others pool data is on ceph version 15.2.15 
(4b7a17f73998a0b4d9bd233cda1db482107e5908) octopus (stable)

On pve-7 I have 10 OSD and for test I want to remove 2 osd from this node.

I write some steps command how I remove this OSD from pve-7 cluster and 
ceph storage.

1) root@pve-7 ~ # ceph osd tree

2) ceph osd reweight
2.1) ceph osd reweight osd.${ID} 0.98
2.2) ceph osd reweight osd.${ID} 0.0 can I set the 0.0 to clean osd.X 
before remove it?

3) When osd is clean from data can I?
ceph osd down osd.${ID}

4) Remove the osd from cluster
ceph osd out osd.${ID}

5) Stop the OSD and umount the osd
systemctl stop ceph-osd@${ID}
umount /var/lib/ceph/osd/ceph-${ID}

6) Remove the osd from CRUSH map:
ceph osd crush remove osd.${ID}

7) Remove the user of OSD:
ceph auth del osd.${ID}

8) And now full delete the OSD:
ceph osd rm osd.${ID}

9) Last command

ceph osd tree (removed OSD not showing

Can some one suggest me my steps command is correct ?

Or I need change some steps?

Thanks .
