How this could work ? If you want to check all the subvolumes files permissions, this will require some time: you need to traverse all the subvolume-filesystem; and only if all the checks are passed, you can delete the subvolume. Unfortunately I think that only two options exist: - don't check permissions, and you can quick remove a subvolume - check all the permissions, i.e. check all the files permissions, and only if all the permissions are OK, you can delete the subvolume. However this cannot be a "quick" subvolume delete BR G.Baroncelli -- gpg @keyserver.linux.it: Goffredo Baroncelli <kreijackATinwind.it> Key fingerprint BBF5 1610 0B64 DAC6 5F7D 17B2 0EDA 9B37 8B82 E0B5 -- 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
