how do you deal with the "clock skew detected" HEALTH_WARN message? I think the internal RTC in most x86 servers does have 1 second resolution only, but Ceph skew limit is much smaller than that. So every time I reboot one of my mons (for kernel upgrade or something), I have to wait for several minutes for the system clock to synchronize over NTP, even though ntpd has been running before reboot and was started during the system boot again. Definitely you should use chrony with iburst.
