[ceph-users] Ceph MON can no longer join quorum

I have a MON that at some point lost connectivity to the rest of the cluster and now cannot rejoin. Each time I restart it, it looks like it's attempting to create a new MON and join the cluster, but the rest of the cluster rejects it, because the new one isn't in the monmap. I don't know why it

Just for clarity since I didn't see it explained, but how are you accessing Ceph using ESXI? Is it via iscsi or NFS? Thanks. Brad McNamara -Original Message- From: ceph-users-boun...@lists.ceph.com [mailto:ceph-users-boun...@lists.ceph.com] On Behalf Of Maciej Bonin Sent: Tuesday, Feb
