Hello. I've been building Ceph clusters since 2014 and the most annoying and worst failure is the NTP server faults and having different times on Ceph nodes.
I've fixed few clusters because of the ntp failure. - Sometimes NTP servers can be unavailable, - Sometimes NTP servers can go crazy. - Sometimes NTP servers can respond but systemd-timesyncd can not sync the time without manual help. I don't want to deal with another ntp problem and because of that I've decided to build internal ntp servers for the cluster. I'm thinking of creating 3 NTP servers on the 3 monitor nodes to get an internal ntp server cluster. I will use the internal NTP cluster for the OSD nodes and other services. With this way, I believe that I'll always have a stable and fast time server. If you don't mind, I want to hear your opinions and experiences. Have a great day. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
