Avamar：MCS 在復原後不會啟動：「GSAN 復原時間與儲存的復原時間不符」

之後 GSAN 已回滾，管理主控台伺服器 （MCS） 無法啟動。

“gsan rollbacktime does not match stored rollbacktime」的內容 /usr/local/avamar/var/mc/server_data/mcserver.out：

Database server is running...

MCS 與 GSAN 如果 GSAN 已回滾到上一個時間點。

1.強制 MCS 還原，以便 MCS 和 GSAN 已同步：

dpnctl start mcs --force_mcs_restore 

Identity added: /home/dpn/.ssh/dpnid (/home/dpn/.ssh/dpnid)
dpnctl: INFO: Restoring MCS data...
dpnctl: INFO: MCS data restored.
dpnctl: INFO: Starting MCS...
dpnctl: INFO: To monitor progress, run in another window: tail -f /tmp/dpnctl-mcs-start-output-nnnnn
dpnctl: INFO: MCS started.

2.確認服務正在執行中：

dpnctl status mcs 

Identity added: /home/admin/.ssh/admin_key (/home/admin/.ssh/admin_key)
dpnctl: INFO: MCS status: up.

3.重新啟動備份排程器：

dpnctl start sched 

Identity added: /home/admin/.ssh/admin_key (/home/admin/.ssh/admin_key)
dpnctl: INFO: Resuming backup scheduler...
dpnctl: INFO: Backup scheduler resumed.
dpnctl: INFO: No /usr/local/avamar/var/dpn_service_status exist.

4.確認所有必需的服務均已啟動：

dpnctl status 

dpnctl: INFO: gsan status: up
dpnctl: INFO: MCS status: up.
dpnctl: INFO: emt status: up.
dpnctl: INFO: Backup scheduler status: up.
dpnctl: INFO: Maintenance windows scheduler status: enabled.
dpnctl: INFO: Unattended startup status: enabled.
dpnctl: INFO: avinstaller status: up.
dpnctl: INFO: ConnectEMC status: down.
dpnctl: INFO: ddrmaint-service status: up.
dpnctl: INFO: [see log file "/usr/local/avamar/var/log/dpnctl.log"]
