Hi. I have a Proxmox cluster of 3 nodes with local storages.
I am testing a live migration VM migration with CentOS 7 and PostgreSQL installed running performance tests to simulate workload.
When trying to live migration between nodes, the migration never ends - the volume of transferred data begins to grow at 96% and the migration percentages are constantly around 96-98%. I tried to run the test for 8 hours - the migration did not end until the load was removed.
I've tried limiting the read and write performance of the VM to disk. The first attempt at migration without VM limits showed 300 Mb / s for reading and 100 Mb / s for writing on average. The second attempt with a limitation, the VM shows 25 Mb / s for reading and 13 Mb / s for writing on average. At the same time, the situation with% has not changed in any way.
I tried disabling SSH data transfer (migration: type = insecure) - it also didn't help. There is no other load on the cluster nodes.
Any ideas?
