[Jayesh]

Hi,

I am facing intermittent clock skew issues on my 3 node proxmox+ceph cluster.

clock skew detected on mon.proxmox3

mon.proxmox3 clock skew 0.0609687s > max 0.05s (latency 0.000392331s)

pasted few information about my current configuration below..

you can try to install chrony as ntp client alternative (apt install chrony), it's really faster to keep clock sync
