Issue

  • The MGWD (Management Gateway) service is kept restarting after initiated SVM (Storage Virtual Machine) DR.
  • And the MGWD Panic string is below.
Example
[HostnameA: mgwd: ucore.panicString:error]:: 'mgwd: assertion ("CpsRdbMonitor failed to lock" == 0) at src/cps/cps_rdb_locking.cc:50 failed, raising SIGABRT(6) at RIP 0x81ab6aeda (pid 8243, uid 0, timestamp 1608113419)'
  • On the partner node, the MGWD service is also offline.
Example
::> set advanced
HostnameB::*> cluster ring show

Node UnitName Epoch DB Epoch DB Trnxs Master Online
--------- -------- -------- -------- -------- --------- ---------
HostnameA mgmt 0 2130 88 - offline ***
HostnameA vldb 56 56 1 WPMPNASCL01A master
