Is this 'btrfs sub del' with 100 subvolumes listed? What happens if the delete command is issued with all 2500 at once? Deleting snapshots is definitely expensive, and deleting them one at a time is more expensive in total time than deleting them in one whack. But I've never deleted 100 or more at once. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
