4.2. Removing Servers from the Trusted Storage Pool
Warning
Before detaching a peer from the trusted storage pool, make sure that the clients are not using the node. If backup servers were not set at mount time using the backup-volfile-servers option, remount the volume on the client using the IP address or FQDN of another server in the trusted storage pool to avoid inconsistencies.
Run
gluster peer detach server to remove a server from the storage pool.
Removing One Server from the Trusted Storage Pool
Remove one server from the Trusted Storage Pool, and check the peer status of the storage pool.
Prerequisites

glusterdservice must be running on the server targeted for removal from the storage pool. See Chapter 24, Starting and Stopping the glusterd service for service start and stop commands. - The host names of the target servers must be resolvable by DNS.
- Run
