问题

由于 VIFMgr 在看门狗超时之前没有响应、并且在重新启动 MDB 时无法恢复该节点，因此该节点出现故障：

Panic String: PANIC : Process vifmgr unresponsive for 629 seconds version: 9.1P12

由于卷 0 上的快照增量和快照空间利用率较高而填满根卷，这是由于运行了 2 周的滚动数据包跟踪所导致的：

Mon Mar 30 08:28:37 CDT [nodename: rshd_0: kern.cli.cmd:debug]: Command-line input: The command is 'pktt'. The full command line is 'pktt start a0a-10 -d /etc/crash -m 9018 -b 8m -s 2g -r 12'.

在出现紧急情况之前、控制台日志显示 VIFMgr 和 VLDB 崩溃、无法重新启动：

Apr 13 00:49:45 [nodename:spm.vldb.process.exit:EMERGENCY]: Volume Location Database(VLDB) subsystem with ID 34409 exited as a result of signal normal exit (1). The subsystem will attempt to restart.

Apr 13 00:49:47 [nodename:spm.vifmgr.process.exit:EMERGENCY]: Logical Interface Manager(VifMgr) with ID 34415 aborted as a result of signal normal exit (1). The subsystem will attempt to restart.

当节点重新引导时，由于卷 0 上缺少空间而无法恢复 MDB ：

Apr 13 02:54:46 [nodename:callhome.mdb.recovery.unsuccessful:EMERGENCY]: Call home for MDB RECOVERY UNSUCCESSFUL FOR THE notifyd WARNING.
