Title:
System Lockup during failover
Status in linux package in Ubuntu:
Incomplete
Status in multipath-tools package in Ubuntu:
Confirmed
Bug description:
When testing failover for configured multipath devices, I am seeing
some nodes lock up and become unresponsive. These nodes have frozen
consoles, but can be pinged. So some of the network stack is
functional, but ssh is not possible to them.
1) 20.04 focal
2) 0.8.3-1ubuntu2
3) multipathing failover would be successful across all nodes and the nodes
would continue to be responsive
4) some of the nodes lock up when attempting to failover and cannot be
reached via ssh or console
