similar to: [PATCH] Btrfs: fix cleaner thread not working with inode cache option

Add a mount option user_subvol_rm_allowed that allows users to delete a (potentially non-empty!) subvol when they would otherwise we allowed to do an rmdir(2). We duplicate the may_delete() checks from the core VFS code to implement identical security checks (minus the directory size check).

Hi Chris, This is the extent of my current queue of Btrfs snapshot/subvol/commit stuff. Most of these were posted several months ago. Can be sent upstream during this merge window? Not having this functionality is becoming a bit of a roadblock for our efforts to keep the Ceph data in a consistent state. These patches are also available from

I've just tried putting usr in a subvol. Installation proceeds normally, no errors, but I'm dropped to a dracut prompt which indicates mount of /usr failed. dmesg follows: [ 14.025215] systemd[1]: Starting dracut initqueue hook...

Hi, I will send a series patches that add snapshot/subvol deletion soon. But the way to delete snapshot/subvol is far from people''s expectancy. To delete a snapshot/subvol, we need four steps: 1) snapshot/subvol deletion ioctl or rmdir; 2) umount; 3) btrfsck; 4) mount the fs. The reason for this is bug in root back & forward references. In simple terms, the bug prevents us from

Is btrfs subvol support failing just for me? Looks like nothing adds the required '@/' string. virt-ls uses the first variant of the command: ><rescue> mount -vo subvol=var/spool,ro /dev/sda2 /sysroot/ [ 113.852047] BTRFS info (device sda2): disk space caching is enabled [ 113.852869] BTRFS: has skinny extents mount: mount(2) failed: No such file or directory ><rescue>

This testscript creates reflinks to files on different subvolumes, overwrites the original files and reflinks, and moves reflinked files between subvolumes.

The code to parse btrfs subvol entries in /etc/fstab failed if the entry had more than one comma-separated option, for example: /dev/sda4 /home btrfs rw,user,subvol=foo 0 0 This commit fixes that code to use Augeas correctly.

Hi all, enclose a patch to improve the "btrfs subvolume find-new" command. This is a RFC because it is not finished, but it is an usable state and may be discussed. The aim of this patch is: - take in account not only an update of the extent but also an update of the inode and xattr (which includes the acl) - extract the generation reference number directly from a snapshot The new

This gives EXDEV for clone operations that btrfs could otherwise execute and with slight change of circumstances will actually execute fine. Imagine we have a btrfs on /dev/mapper/foobar with subvols /foo and /bar. Let’s also imagine top of said fs in mounted at /mnt. In this case, a cross-subvol clone of /mnt/foo/srcfile to /mnt/bar/dstfile will succeed. However, if only the individual

We create two subvolumes (meego_root and meego_home) in btrfs root directory. And set meego_root as default mount subvolume. After we remount btrfs, meego_root is mounted to top directory by default. Then when we try to mount meego_home (subvol=meego_home) to a subdirectory, it failed. The problem is when default mount subvolume is set to meego_root, we search meego_home in meego_root but can not

Hi, I have a box with / and /home being subvolumes from the same btrfs filesystem. /etc/fstab: UUID=c0686... / btrfs subvol=root,x-systemd.device-timeout=0 1 1 UUID=c0686... /home btrfs subvol=home,x-systemd.device-timeout=0 1 1 ... / is initially mounted readonly by the initramfs, and then after switching to the real system, /home is attempted to be mounted in parallel with /
