Hi All,
I have a four node ceph cluster. But the command ceph –s shows health
warning. How should I safely synchronize time across the nodes.
Try to run this first:
$ ceph health detail
It will tell you the skew per monitor.
Afterwards install NTP on all the monitors to make sure the times are
synced.
You can initially sync with ntpdate and have the ntp daemon take over
afterwards.

The OS platform is Ubuntu.
