Hello Everyone,
So here is v2. Patch 1 can already be merged independently of the others.
Regards,
Lukas Straub
Changes:
v2:
-use new yank api
-drop disk_size parameter
-introduce pick_qemu_util function and use it
Overview:
Hello Everyone,
These patches introduce a resource agent for fully automatic management of colo
and a test suite building upon the resource agent to extensively test colo.
Test suite features:
-Tests failover with peer crashing and hanging and failover during checkpoint
-Tests network using ssh and iperf3
-Quick test requires no special configuration
-Network test for testing colo-compare
-Stress test: failover all the time with network load
Resource agent features:
-Fully automatic management of colo
-Handles many failures: hanging/crashing qemu, replication error, disk error,
...
-Recovers from hanging qemu by using the "yank" oob command
-Tracks which node has up-to-date data
-Works well in clusters with more than 2 nodes
Run times on my laptop:
Quick test: 200s
Network test: 800s (tagged as slow)
Stress test: 1300s (tagged as slow)
The test suite needs access to a network bridge to properly test the network,
so some parameters need to be given to the test run. See
tests/acceptance/colo.py for more information.
I wonder how this integrates in existing CI infrastructure. Is there a common
CI for qemu where this can run or does every subsystem have to run their own
CI?
Regards,
Lukas Straub
