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
- The
glusterdservice must be running on the server targeted for removal from the storage pool. See Chapter 22, 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
gluster peer detach [server]to remove the server from the trusted storage pool.gluster peer detach (server)
# gluster peer detach (server) All clients mounted through the peer which is getting detached needs to be remounted, using one of the other active peers in the trusted storage pool, this ensures that the client gets notification on any changes done on the gluster configuration and if the same has been done do you want to proceed?
