Does it happen when you have a high load average ?
No machines are Idle but i can't understand why the clock changes are so
extreme...

damn, this is strange...
are you sure that your ntp daemon is running ? (If I remember good, ntpdate
can't run if ntpd is already running)
# ntpdate 0.debian.pool.ntp.org

Objet: [pve-devel] clocks not syncronized in ceph
Hello,
on my ceph cluster i get always the message clocks not syncronized. But
i'm running openntpd on all nodes.
Time is always different like this:
0.050004s in the future, clocks not synchronized
I can also run ntpdate manual multiple times and it will syncronize
again and again.
/root/sshall "ntpdate pool.ntp.org"
