检查 web.log 显示:
2021-12-20T05:11:52.456+0000 ERROR [myScheduler-9] com.emc.mystic.manager.cluster.service.HostEnrichServiceImpl HostEnrichServiceImpl.enrichHostInfo:58 - Failed to fetch host enriched info. java.lang.NullPointerException: null


检查 short.term.log 显示:
2021-12-20-05:17:18 microservice.do-host "2021-12-20 05:17:18,146 [ERROR]  linzhi_dataloader.py fetch_async() (67): Query data failed,url:https://ESXI-hostname:9090/rest/ps/private/v1/nodeinfo, Exception:Cannot connect to host ESXI-hostname:9090 ssl:False [Temporary failure in name resolution]"


在 VxRail Manager 上使用 nslookup 或 dig 命令显示主机名解析正常,但在 do-cluster 容器内检查时,其失败。

以 root 用户身份在 VxRail Manager 上运行以下命令(例如,ESXi FQDN 为“esx01.xyz.com”,将其替换为真实主机 FQDN)。

vxm:~ # docker exec -it -u 0 $(docker ps -q -f name=do-cluster) dig esx01.xyz.com
;  DiG 9.16.6  esx01.xyz.com
;; global options: +cmd
;; connection timed out; no servers could be reached
 
vxm:~ # docker exec -it -u 0 $(docker ps -q -f name=do-cluster) ping esx01.xyz.com
 
ping: esx01.xyz.com: Temporary failure in name resolution

Cause

容器使用 VxRail manger 作为 DNS 服务器。如果 VxRail Manager DNS 服务出现问题,则主机名解析失败。

Resolution

使用以下命令在 VxRail manger 上重新启动 DNS 服务:
systemctl restart dnsmasq

等待 10 分钟,然后再次检查物理视图。
