And one more push, which has everything I've been sent recently integrated. This includes Josef's /sys/fs/btrfs/<device> stuff to expose details about blocks used in each root. If you want to look at the block accounting, you will want to pull the related changesets from the btrfs-progs tree as well. I modified Yan Zheng's port of Christoph's mount-into-subdir patch. If you mount a btrfs volume, you will end up in the default subvolume by default. You can mount as many subvolumes as you want: mount -t btrfs -o subvol=name /dev/xxxx /mount_point Note the -t btrfs, mount needs it if you've already got something mounted from that device. You can create snapshots right off the mount points: btrfsctl -s snapname /mount_point But to create a new subvolume, you have to mount the tree root: mount -t btrfs -o subvol=. /dev/xxx /mount_point Which will give you the same directory tree btrfs used to have at its root. -chris _______________________________________________ Btrfs-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/btrfs-devel
