Is that just the file entry in "/var/lib/glusterd/peers" ?


e.g I have:

    gluster peer status
    Number of Peers: 3

    Hostname: vnh.proxmox.softlog
    Uuid: 9eb54c33-7f79-4a75-bc2b-67111bf3eae7
    State: Peer in Cluster (Connected)

    *Hostname: vna.proxmox.softlog**
    **Uuid: de673495-8cb2-4328-ba00-0419357c03d7**
    **State: Peer in Cluster (Disconnected)**
    *
    Hostname: vnb.proxmox.softlog
    Uuid: 43a1bf8c-3e69-4581-8e16-f2e1462cfc36
    State: Peer in Cluster (Connected)

Do I just:

    rm /var/lib/glusterd/peers/de673495-8cb2-4328-ba00-0419357c03d7


On all the live nodes and restart glusterdd? nothing else?


thanks.

Yes. And please ensure you do this after bringing down all the glusterd
instances and then once the peer file is removed from all the nodes restart
glusterd on all the nodes one after another.

If you have to bring down all gluster instances before file removal, you
also bring down the whole gluster storage
