I never ran any sort of dedup on this partition. > Not pretty sure if it's related to the bug, but did you do the > balance/defrag operation just after removing ext_save subvolume? That's quite possible. I did it in a live boot, so I don't have the bash history to check. I checked it just now using "btrfs subvol list -d", and there's nothing listed. I ran a full balance after that, but the problem remains. So whatever the problem is, it can survive a full balance after the ext_save subvol is completely deleted. --Sean -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
