Removing the manager daemons

To remove the manager daemons from the host, you can just redeploy the daemons on other hosts.

Prerequisites

A running IBM Storage Ceph cluster.
Root-level access to all the nodes.
Hosts are added to the cluster.
At least one manager daemon deployed on the hosts.

Procedure

Log into the Cephadm shell:

Example
```
[root@host01 ~]# cephadm shell
```
Run the ceph orch apply command to redeploy the required manager daemons:

Syntax
```
ceph orch apply mgr "NUMBER_OF_DAEMONS HOST_NAME_1 HOST_NAME_3"
```
If you want to remove manager daemons from host02, then you can redeploy the manager daemons on other hosts.

Example
```
[ceph: root@host01 /]# ceph orch apply mgr "2 host01 host03"
```

Verification

List the hosts,daemons, and processes:

Syntax

ceph orch ps --daemon_type=DAEMON_NAME

Example

[ceph: root@host01 /]# ceph orch ps --daemon_type=mgr
