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.
