Portal:Cloud VPS/Admin/Runbooks/GaleraNoRecentWrites

From Wikitech

The GaleraNoRecentWrites alert fires when the Galera wsrep_last_committed status variable has not increased in the last hour.

The procedures in this runbook require admin permissions to complete.

Error / Incident

Galera has applied no writes in the past hour.


Some tips:

  • Look at the value of the variable on all nodes

Common issues

Single node behind others, all nodes stuck

Once a single Galera node had a lower value than all others. In that case we depooled the node which moved traffic to other nodes, those two nodes then started having new writes applied.
