Yes, you can do that. It's a bit similar to the fact that you can also delete a regular file when it's still open by another program. But, still having a file open (inode, filedescriptor, what's it called...) does actually block the cleaner process from progressing beyond that point. You can also delete a subvolume which is not separately mounted, while a process still has open files in it. In case of deleting a mounted subvolume... it's a bit different. As long as it's mounted, even if nothing else is using a file within, it won't be actually completely deleted in the background, unless the final umount is done. What can happen (I just tried it) is that the mount point ends up looking completely empty already in the meantime, as soon as no files are open and after I cd .. out of it. If I cd back into the mount point, there's nothing any more and any action to create something new within will end up with a "No such file or directory". Only when doing the umount, the subvolume completely disappears. -- Hans van Kranenburg -- 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
