问题描述

节点发生故障、某个进程(vipmgmt、vldb、mgwd等)无响应：

PANIC: Process vifmgr unresponsive for 180 seconds in process nodewatchdog on release 9.7P9 (C) on Sun Nov 21 16:47:29 CET 2021

在启动期间、节点可能会报告以下信息：

[node-01:callhome.mdb.recovery.unsuccessful:EMERGENCY]: Call home for MDB RECOVERY UNSUCCESSFUL FOR THE vifmgr WARNING. [node-01:boot.varfs.backup.issue:EMERGENCY]: Backup of the /var file system failed (cp: /mroot/etc/tmpvarfs.tgz: No space left on device [node-01:callhome.mdb.recovery.unsuccessful:EMERGENCY]: Call home for MDB RECOVERY UNSUCCESSFUL FOR THE crs WARNING. [node-01:callhome.mdb.recovery.unsuccessful:EMERGENCY]: Call home for MDB RECOVERY UNSUCCESSFUL FOR THE bcomd WARNING. [node-01:callhome.mdb.recovery.unsuccessful:EMERGENCY]: Call home for MDB RECOVERY UNSUCCESSFUL FOR THE vifmgr WARNING. [node-01:mgmtgwd.rootvolrec.low.space:EMERGENCY]: The root volume on node "cluster-01" is dangerously low on space. Less than 10 MB of free space remaining.
