Description
Sometimes (maybe after disk failures?) pulpito still shows runs that had been killed.
As of today see "greg-fs-speculative-119" in http://pulpito.ceph.com/?status=running
This run is actually dead.
Not sure what would be a possible solution here, maybe a way in pulpito UI to clean up those, Zack?
Updated by Zack Cerza over 8 years ago
- Project changed from pulpito to teuthology
- Subject changed from pulpito shows killed runs to Bad interaction between deadlocking teuthology processes
- Priority changed from Normal to High
Not pulpito. The worker broke:

There are three issues here:
1. Why did the job deadlock there?
2. -kill/-nuke threw an error instead of gracefully skipping that node
3. -worker deadlocked also!

I can speculate on #1 - because mira115 had bad drives
Updated by Zack Cerza almost 8 years ago
- Status changed from New to Resolved
This should actually be resolved
