Hi, I don’t know why this happens. I have a cluster with 6 nodes + 1 arbitrator and everytime it get out of sync or there is a problem with the cluster (which is currently about every 1 hours in average (the Cluster Software as very unstable in my environment) the nodes are syncing with the same donor. Problem of this is that this is the node with the highest latency. But for me it would make more sense to sync with the node with lowest latency. My nodes are not in the same datacenter but all over the world. Biggest latency is about 500ms.

WSREP: Member 2.0 (garb) requested state transfer from ‘_any_’. Selected 0.0 (xxxxxxxx)(SYNCED) as donor.

Change the order on wsrep\_cluster\_address=gcomm:// because the donor is always the first address of the pool

Have you tweaked the timeout settings?

```auto
wsrep_provider_options = "gmcast.segment=0; gcache.size=1G; evs.suspect_timeout = PT90S; evs.inactive_timeout = PT5M; evs.install_timeout = PT5M; evs.join_retrans_period=PT1.0S"

```

I had to increase the timeouts significantly to handle a cluster spread across data centers on the east and west coasts of the US.
