For clock skew, I setup NTPD on one of the monitors with a public time server to pull from. Then I setup NTPD on all the servers with them pulling time only from the local monitor server. Restart the time service on each server until they get relatively close. If you have a time server setup already in place, that would work as well. Make sure to eliminate the backup time server entry as well. If this is already in place, then what is usually necessary is a restart of the monitor service on the monitor complaining of clock skew. If any are virtualized, make sure the time is not syncing from the host server to the VM, this could be causing the skew as well. -Brent -----Original Message----- From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx] On Behalf Of Dominque Roux Sent: Wednesday, August 15, 2018 5:38 AM To: ceph-users@xxxxxxxxxxxxxx Subject: Clock skew Hi all, We recently facing clock skews from time to time. This means that sometimes everything is fine but hours later the warning appears again. NTPD is running and configured with the same pool. Did someone else already had the same issue and could probably help us to fix this? Thanks a lot! Dominique -- Your Swiss, Open Source and IPv6 Virtual Machine.
