檢查 web.log 顯示:
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

檢查 short.term.log 顯示:
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 命令顯示主機名稱解析正常,但在 do-cluster 容器中檢查主機名稱解析時會失敗。

以 root 使用者身分在 VxRail Manager 上執行以下命令 (例如,ESXi FQDN 為「esx01.xyz.com」,請將它更換為您真正的主機 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 Manager 作為 DNS 伺服器。如果 VxRail Manager DNS 服務發生問題,主機名稱解析會失敗。

Resolution

使用以下命令在 VxRail Manager 上重新啟動 DNS 服務:
systemctl restart dnsmasq

等待 10 分鐘,然後再次查看實體視圖。
