Download/ploop/1.5

ploop is a tool and a library to control ploop block devices.

Warning: this is an old version of ploop. For the latest version, see Download/ploop/1.15.

Compatibility notes

• this version requires running vzkernel >= 2.6.32-042stab061.1
• DiskDescriptor.xml created by older ploop versions are converted to current format
• there were a few incompatible library API changes, see below

Changes

Since version 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
• ploop create, resize: round up size to be cluster 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 umount: print lsof output in case of failed umount
• 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

• add ploop_resolve_functions() to aid in dynamic library loading
• introduce optimized ploop_get_info_by_descr(), remove ploop_get_info()
• replace ploop_{alloc,read}_diskdescriptor() with ploop_read_disk_descr()
• remove ploop_getdevice()
