See this post: https://forum.proxmox.com/threads/proxmoxve-ceph-clock-issue.20684/#post-105441 go to 6th post from the top from stevendemetrius. This is the instruction that I followed and had a caph cluster running for 2 years with no clock skew issues. I have two local NTP servers that I...

I have 7 nodes total. 4 dedicated for VMs and 3 for Ceph only (under Proxmox). For about 2 years they were running as two separate clusters with no issues but now we are reinstalling everything and I am wondering if there would be an advantage to create a 7 node single cluster. Any advice, any...

I have read somewhere quite some time ago that having 1 phisical CPU with high clock is better than having 2 CPU for ceph, is this still that case ? Also how would you know if it is time to upgrade your network from 10Gb to something faster- we are maxing out at about 1.5 Gbps when looking at...

ok so I found explanation of what exactly the apply/commit latency is (before I was just comparing it to what other people were posting) which makes sens for non ssd drives and journal that is on the OSDs (no separate journal drive). Question now what can I do to improve these numbers ? Any...
