Hi,all
My cluster is pacemaker 1.1.7 + corosync 2.0. I have write a
resource agent to manage the virtual machine.The RA supports
start,stop,migrate_from,migrate_to,monitor.
But when I try to migrate a running cluster vm(resource name is
dcbh6f1c-GtNhnB-8597) from the host(h66) to a target host (h65),the
cluster just stops it in host A,and then start it in host B.
I check the pacemaker log and find that ,it just don`t execute the
migrate action!
My command is crm resource migrate dcbh6f1c-GtNhnB-8597 h65.
