Hi All,
Putting out a call for help to see if anyone can shed some light on this.
Configuration:
Ceph cluster presenting RBD's->XFS->NFS->ESXi
Running 10.2.7 on the OSD's and 4.11 kernel on the NFS gateways in a
pacemaker cluster
Both OSD's and clients are go into a pair of switches, single L2 do
19 matches
