UIS NTP Server time Edit

NULL

The customer uses the UIS master node as the NTP Server, and then finds that the master node time is slower than the actual time. And hopes to synchronize the time to the normal time

The current version (after P0721) of UIS supports time adjustment within 30 days, and can support time adjustment forward or backward.

Please note that the following operations should be performed in a certain time window, which may cause a brief business interruption.

For edit the time of the NTP Server, you can do these step by step.

1.     Close the time sync for all the VM. VM-Edit-

2.     At the NTP Server excute date -s YYYY-MM-DD hh:mm[:ss]（for example：date -s “2022-03-14 10:30:00”）

3.     At other node excute ntpdate –u NTP_Server_IP command to sync the time（for example ntpdate –u 10.125.36.101）

4.     Excute watch date make sure every node has the same time.

5.     Excute systemctl restart tomcat8 at the management node to restart the tomcat service.

6.     Run the ceph –s command to confirm that the status is HEALTH_OK. If clock skew is detected, wait for system synchronization. If osd is down, run the ceph-disk activate-all command to start the service.

7.     After logging into the platform successfully, check the storage interface and the storage data should be displayed normally.

8.     Determine whether to enable the virtual machine time synchronization service function based on actual application conditions.
