features/qemu-block: support for QCOW2 and QED formats
This patch adds support for internals snapshots using QCOW2 and general framework for external snapshots (next patch) with QCOW2 and QED. For internal snapshots, the file must be "initialized" or "formatted" into QCOW2 format, and specify a file size. Snapshots can be created, deleted, and applied ("goto"). e.g: // Format and Initialize sh# setfattr -n trusted.glusterfs.block-format -v qcow2:10GB /mnt/imgfile sh# ls -l /mnt/imgfile -rw-r--r-- 1 root root 10G Jul 18 21:20 imgfile // Create a snapshot sh# setfattr -n trusted.glusterfs.block-snapshot-create -v name1 imgfile // Apply a snapshot sh# setfattr -n trusted.gluterfs.block-snapshot-goto -v name1 imgfile Change-Id: If993e057a9455967ba3fa9dcabb7f74b8b2cf4c3 BUG: 986775 Signed-off-by: Anand Avati <avati@redhat.com> Reviewed-on: http://review.gluster.org/5367 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
