I'm using Fedora 12 x86_64, mostly with the newer 21.6.32 kernel, and have a single btrfs filesystem within a 120Gb partition. I'd like to extend the space btrfs can use. One option is presumably add a new device to btrfs, but I was hoping to simple resize the existing partition to say 160Gb. With ext4 I might do this with gparted , although mostly I'd use LVM, with seperate LVs for /opt /home / etc and that's been the way I've done it for many years. With btrfs I'm unsure as to the safe steps and decided to skip on use of LVM giving the enhanced capabilities of btrfs itself. Is it ok to resize the partition with gparted? How do I make btrfs use the new partition size? Or are there other btrfs specific tools that can manage partitions Would I be better off still using lvm in conjunction with btrfs? Are there good pointers to useful user material on btrfs on these issues? Is creating new subvolumes to manage /home (say I want to limit that space, and create snapshots independently) appropriate, and if so what's the easiest way to do that -- I had trouble with getting the subvolume ops to work Mostly rather than NEED btrfs per se, I'm using a clean laptop environment as a way to experiment with the new filesystem & understand how to manage it. Thanks Nigel. bugs@cherrybyte.me.uk
