Revision as of 00:13, 8 September 2012
Compatibility notes
- this version requires running vzkernel >= 2.6.32-042stab061.1
- snapshots created by old ploop tools are not compatible with this version
- there were a few incompatible library API changes, see below
Changes
Since 1.4
New functionality
- switch from old /dev/ploop/ symlink-based to new in-kernel cookie registration
- snapshots: switch to schema with constant top delta uuid
- use /proc/vz/ploop_minor based interface to get free minor
- if ploop device is in maintenance state, try to complete it before doing snapshot/resize/merge/mount/umount/copy operation
- ploop mount: use in-kernel I/O module autodetection
- ploop balloon discard: new iterative compacting support
- ploop balloon discard: implement --stat
- ploop balloon discard: implement --automount
- ploop balloon discard: cancellation support
- ploop balloon: allow DiskDescriptor.xml argument
- ploop umount: implement -c component_name
- ploop list: implement
- /sbin/mount.ploop: do load ploop modules
Bug fixes
- do not crash on empty DiskDescriptor.xml (libxml2 workaround)
- ploop convert: fix converting from expanded to raw
- ploop copy: fixed check for opened fd
- ploop copy: do not leak opened fds
- ploop create: fix gpt partition creation to be 4096 aligned
- tools: few exit code fixes
- multiple usage, log and error message fixes
Improvements
- ploop mount: check that mount point is a directory
- ploop umount: reduce retry count from 60 to 6
- ploop create: for prealloc image, use ftruncate if fallocate not supported
- ploop create, resize: add check for correct block device size
- scripts: de-bash-ify
- assorted code refactoring, cleanups and nitpicks
Library API changes
- implement dynamic library loading via ploop_resolve_functions()
- introduce optimized ploop_get_info_by_descr(), remove ploop_get_info()
- replace ploop_{alloc,read}_diskdescriptor() with ploop_read_disk_descr()
- remove ploop_getdevice()
