While you have this paged in, could you add a comment with a synopsis here? Something like a (better version of)
// Checks that when a node has all of its replicas taken away in absentia restarts without being able to talk to any of its old peers, it will still replicaGC its replicas quickly.
pkg/cmd/roachtest/replicagc.go, line 69 at r1 (raw file):
} t.Status("waiting for zero replicas on n1 and n2")
remove "and n2"
pkg/cmd/roachtest/replicagc.go, line 81 at r1 (raw file):
// attribute. We'll later start n3 using this attribute to test GC replica // count. h.isolateDeadNodes(ctx, 4)
// run this on n4 (it's live, that's all that matters)
Fixes cockroachdb#51097. Fixes cockroachdb#51367. This is fallout from cockroachdb#50329, this test previously attempted to recommission a fully decommissioned node. It seems we relied on the decomm/recomm subsystems to trigger replica gc operations, that that test was then asserting on. It suffices to simply mark the nodes as decommissioning instead of fully decommissioning them. While here, I've re-written this test in the more stateful style of the `decommission-recommission` roachtest. Release note: None
