異地雙機容災常見命令
| 命令 | 含義 |
|---|---|
| vxdctl -c mode |
找到mater節點 |
| vradmin -l printrvg |
檢視節點是否是primary，並檢視dg和rvg名稱 |
| vxrlink -g dgcfsname -i 2 status link1name |
檢視當前鏈路複製狀態，需要為up to date狀態才能停止複製 |
| vradmin -g dgcfsname stoprep rvgcfsname |
停止複製，根據提示輸入y |
| vradmin -g dgcfsname -f stoprep rvgcfsname |
強制停止複製，根據提示輸入y |
| vradmin -g dgcfsname -a startrep rvgcfsname |
開始全複製 |
| vradmin -g dgcfsname repstatus rvgcfsname |
檢視複製狀態 |
| vrstat -g dgcfsname -R |
檢視複製速率，會一直重新整理，退出時可以按ctrl c |
異地雙機重新全同步步驟如下
1.查詢master節點
[[email protected] ~]# vxdctl -c mode
mode: enabled: cluster active - MASTER
master: TESTSERVER1A2.登陸master節點，檢視當前是否為primary
[[email protected] ~]# vradmin -l printrvg Replicated Data Set: rvgcfsname Primary: HostName: 10.228.170.154 <localhost> RvgName: rvgcfsname DgName: dgcfsname datavol_cnt: 11 vset_cnt: 0 srl: lvtestsrl RLinks: name=link1name, detached=off, synchronous=off Secondary: HostName: 10.225.170.154 RvgName: rvgcfsname DgName: dgcfsname datavol_cnt: 11 vset_cnt: 0 srl: lvtestsrl RLinks: name=link2name, detached=off, synchronous=off
3.檢視當前鏈路複製狀態，需要為up to date狀態才能停止複製
