TOPIC: Slave hosting all VMs not responding, what to do ?

Slave hosting all VMs not responding, what to do ? 10 months 1 week ago #1479

Hi,
i have a HA-Lizard Pool on XenServer 7.2

Suddenly XenCenter cannot connect to Pool
All the VMs are running on the Slave, they're working and i can only connect via SSH but nothing seems to respond.

I attached results for both master and slave iscsi-cfg status and ha-cfg status

What can i do to exit this situation without losing any VM ?

Thank you

here is what i can gather from the information supplied

- the storage and vms disk images are ok. the master is still replicating and exposing the storage

- ha is disabled. this is fine

- the slave cannot connect to the api on the master. this is probably due to a network issue, or more likely xapi has entered a hung state on the master.

i would try restarting the toolstack on the master. if ha-cfg status on the slave no longer reports timeout, the problem has cleared

xe-toolstack-restart on Master ... still TIMEOUT followed by xe-toolstack-restart on slave and everything is now as it should be.

Thank you
