It seems that there is a partial PG exception, MON can not be determined correctly, and needs to be manually operated. Can refer to https://docs.ceph.com/docs/mimic/rados/troubleshooting/troubleshooting-pg/

Thank you for your answer, but the test environment is not so much money, haha! It is enough to write 50M/s ~ 60M/s in a redundant shared storage, but I didn't expect it to be so low.

It's just a consumer-grade SSD( kingston 480G mstat), but the test environment doesn't pay much attention to the hardware requirements. Reading 150M/S is normal, but writing only 800KB/S is not normal, even ordinary HDD is not.

2 interface, just a test environment, nothing runs during the test.

I was deploying a small node and found that write performance using lxc was very poor. My network is 1G, but it is not so bad. Is there any place to check? my config: nodes: 4 CPU: i5-8250U RAM: 32G HDD1: 128G SSD HDD2: 480G SSD pve version: root@tpa-pve1:~# pveversion...

Has anyone encountered an OSD conflict?

Recently I tried to replace the PVE node. An error occurred. There is a conflict between adding mon. After adding a mon, another mon is displayed as out of quorum, but the service and the log do not display an exception. Close the newly added mon to return to normal. Have you seen a solution...

Would like to ask, can you set the Pool to make all Primary dg in an osd?

Well, as you can see from this picture, do you have a shared storage solution that can be used in a production environment?

After modifying min_site, the test results are the same as before. It is necessary to wait for the osd heartbeat. It is considered that the problematic OSD is DOWN to resume writing.

Thank you for pointing out the mistake. Just a minimal cluster, 3host: 1host only 1osd, CEPH config except pool mini_size=1, othe default config, found in mysql imprort data for single point of failure test can not be written.

During the test, it was found that there were 3 OSDs running in CEPH, one OSD network was interrupted or the host was powered off and restarted. All VMs using CEPH need to wait for the OSD heartbeat to be used normally. In the production environment is not very friendly, in addition to modifying...

I recently tested pve and planned to deploy. If you have any questions, please consult: 1. What is the reason why the design node network configuration is not automatically set in real time? 2. What features does the Subscription Plans Complete feature-set contain?
