So I have some context with the replica fetcher area (mostly by reading and debugging), I hope I can help. First, since the conversation is a bit long, let me summarize what I understand: - The problem is disk A reaches its capacity limits - The solution is to move partition X-1 to disk B - During the reassignment, log cleaning is disabled on X-1 (which can therefore fill disk A) - The reassignment of X-1 fails, it is left failed there on B and X-1 on A keeps growing Is this correct? If it is, we may need to separate the deletion and compaction cases. I think resuming deletion is safe, however resuming compaction might not be, since compaction alters the log. If an operator somehow resumes B and lets replication continue, then the history of X-1 in A and B might be different (I'm still working on a local test case that reproduces this).
