VMware vcsa、esxi、vsan排错及架构简介？

VSAN 问题处理的基本思路

1、登陆VC

通过网页版本登陆vsphere web client

2、检查VSAN 运行状况

Vc 上选择VSAN 集群-> 监控-> Virtual SAN-> 运行状况 查看是否有报错信

3、检查日志

less /var/log/vmkernel.log | grep -iE ‘error | reset | congestion’

less /var/log/vobd.log | grep -iE ‘error | reset | congestion’

4、检查网络情况

通过以下命令排除网络问题：

esxcfg-nics -l

esxcfg-vmknic -l

esxcli network ip interface ipv4 get

vmkping -I vmk1 9.2.8.154

5、检查VSAN 存储

esxcli vsan cluster get

esxcli vsan storage list | grep CMMD

esxcli vsan storage list | grep SSD

vdq -iH

6、查看VSAN 全局拥堵情况

for ssd in $(localcli vsan storage list |grep "Group UUID"|awk '{print $5}'|sort -u);do echo $ssd;vsish -e get /vmkModules/vsan/lsom/disks/$ssd/info|grep Congestion;done

7、查看VSAN 拥堵明细

for ssd in $(localcli vsan storage list |grep "Group UUID"|awk '{print $5}'|sort -u);do llogTotal=$(vsish -e get /vmkModules/vsan/lsom/disks/$ssd/info|grep "Log space consumed by LLOG"|awk -F \: '{print $2}');plogTotal=$(vsish -e get /vmkModules/vsan/lsom/disks/$ssd/info|grep "Log space consumed by PLOG"|awk -F \\: '{print $2}');llogGib=$(echo $llogTotal |awk '{print $1 / 1073741824}');plogGib=$(echo $plogTotal |awk '{print $1 / 1073741824}');allGibTotal=$(expr $llogTotal \+ $plogTotal|awk '{print $1 / 1073741824}');echo $ssd;echo " LLOG consumption: $llogGib";echo " PLOG consumption: $plogGib";echo " Total log consumption: $allGibTotal";done

8、Unmount 异常的磁盘组

localcli vsan storage diskgroup unmount –ssd=naa.55cdddddffffffff

9、重启ESXI

根据故障判断是否需要重启ESXI

10、验证

验证ESXI和VM 是否恢复
