Servers went down due to failed query. I bootstrapped cluster and was unable to start the remaining nodes with the following error:
2018-10-12 20:12:15 0 [Warning] WSREP: SST position can't be set in past. Requested: 92172, Current: 3620686.
2018-10-12 20:12:15 0 [Warning] WSREP: Can't continue.
2018-10-12 20:12:15 0 [ERROR] Aborting
It says the current commit is 3620686, but it was actually 9953033. Not sure why this matters since the cluster was restarted and that number restarted.
