Stupid Galera fucks up every now and then. If there’s only one node left and it doesn’t start with:

[ERROR] WSREP: failed to open gcomm backend connection: 110: failed to reach primary view: 110 (Connection timed out)

Then you need to “bootstrap” it:

In grastate.dat:

safe_to_bootstrap: 0

Must be 1 not 0!

And then just do:

service mysql start –wsrep-new-cluster

Unstable crap…
