Risk Events

A critical bug that introduced in V1.0.0 had been fixed in v1.0.8.
if the user want to scale in some TiKV nodes with the command tiup cluster scale-in with tiup-cluster, TiUP may delete TiKV nodes by mistake, causing the TiDB cluster data loss
The root cause:

  1. while TiUP treats these TiKV nodes' state as tombstone by mistake, it would report an error that confuses the user.
  2. Then the user would execute the command tiup cluster display to confirm the real state of the cluster, but the display command also displays these TiKV nodes are in tombstone state too;
  3. what's worse, the display command will destroy tombstone nodes automatically, no user confirmation required. So these TiKV nodes were destroyed by mistake.

To prevent this, we introduce a more safe manual way to clean up tombstone nodes in this release.
