hi
running ceph -w I see many of those warnings flying by:
10.07.08_14:36:49.897108 log 10.07.08_14:36:48.530057 mon1 192.168.1.52:6789/0 340 : [WRN] lease_expire from mon0 was sent from future time 10.07.08_14:36:48.886876, clocks not synchronized
10.07.08_14:36:49.897108 log 10.07.08_14:36:48.530076 mon1 192.168.1.52:6789/0 341 : [WRN]
i've stopped ceph, ran ntpdate on every node, started ceph
- the message is still there.
date from the nodes:
# for i in node001 node002 node003 node004; do ssh root@$i date; done
