Hi,
we are testing drbd9 with 3 node. After a test (network disable, then
enable on one host), the syncronization is not finishing.
As a recovery, I switched the pacemaker off, and I tried "primary --force"
on one node and "--discard-my-data" on the other nodes. It seem solve the
problem (everything is UpToDate), but after I down/up the resource, the
"neverending" synchronization is restarted (when the resource is Secondary
on all the 3 node).
Why sync is restarted after UpToDate state. Ho can I solve this problem?
Nodes are xetes1, xetest2, xetest3, here is a checking test ("drbdadm
status" on every node, then wait 10 secod. This repeated 10 times)
Thanks for answers: Laci.
