No move operation in progress, can't resume

Error message

No move operation in progress, can't resume

What it means

resumeMove requires an in-progress MOVE sequence in ClusterMetadata. If metadata.inProgressSequences has no MOVE for the local node, it throws IllegalStateException 'No move operation in progress, can't resume' - and as a courtesy clears a stale MOVE_FAILED StorageService mode if one is set.

Solutions

1. Confirm with `nodetool ring` whether the move actually completed - if so, no resume is needed.
2. Check `nodetool inprogresssequences` for a MOVE entry for this node before resuming.
3. If StorageService mode was MOVE_FAILED but nothing is in progress, the command already cleared the transient mode; re-run move instead.
4. Retry the move from scratch if the original one was aborted.

Example fix

// before
nodetool resumemove   // IllegalStateException: no move in progress
// after
nodetool ring          # verify tokens already moved
nodetool move <token>  # start a new move if needed

MultiStepOperation<?> seq = ClusterMetadata.current().inProgressSequences.get(self);
if (seq == null || seq.kind() != MultiStepOperation.Kind.MOVE)
    return; // nothing to resume

boolean hasMoveInProgress(NodeId self) { MultiStepOperation<?> s = ClusterMetadata.current().inProgressSequences.get(self); return s != null && s.kind() == MultiStepOperation.Kind.MOVE; }

try { resumeMove(); }
catch (IllegalStateException e) { if (e.getMessage().contains("No move operation in progress")) { verifyMoveCompletedOrRestart(); } else throw e; }

When it happens

Trigger: Running `nodetool resumemove` when there is no MOVE multi-step operation registered for this node: the move fully completed, was already aborted, or never started on this node.

Common situations: Calling resumemove by mistake on a node where the move succeeded (finishInProgressSequences already ran); resuming after an abort; running the command on the wrong host.
