Testing btrfs snapshots and git on ramdisk (tmpfs)

gistfile1.txt

These are my notes while testing.

Ubuntu LTS 10.04 doesn't support removing btrfs snapshots. It can be fixed by installing newer btrfs.

    cd /tmp
    wget "http://se.archive.ubuntu.com/ubuntu/pool/main/b/btrfs-tools/btrfs-tools_0.19+20100601-3ubuntu3_i386.deb"
    dpkg -i btrfs-tools_0.19+20100601-3ubuntu3_i386.deb

Mounting btrfs image:

    mount -o loop /ramdisks/raw/disk0 /ramdisks/mnt/disk0


Creating snapshot:

    btrfsctl -s /ramdisks/mnt/disk0/snapshot/disk0-20120124-2149 /ramdisks/mnt/disk0/data
