Version 2.02.28 -
================================
Version 2.02.28 - 24th August 2007
==================================
Fix clvmd logging so you can get lvm-level debugging out of it.
Introduce VG_GLOBAL lock type for vgscan/pvscan to trigger clvmd -R.
Change locking_flags from int to uint32_t.
Fix clvmd -R, so it fully refreshes the caches.
Change lvconvert_mirrors to use mirror segtype not striped.
Fix lvconvert_mirrors detection of number of existing mirrors.
Clean up numerous compiler warnings that crept in recently.
Clean up numerous compiler warnings that appeared in recent releases.
Remove several unused parameters from _allocate().
Only permit --force, --verbose and --debug arguments to be repeated.
Move guts of vgremove into library.
Fix inconsistent licence notices: executables are GPLv2; libraries LGPLv2.1.
Move guts of lvremove into library.
Allow clvmd debug to be turned on in a running daemon using clvmd -d
Move guts of vgremove and lvremove into library, including yes_no_prompt.
Allow clvmd debug to be turned on in a running daemon using clvmd -d [-C].
Update to use autoconf 2.61, while still supporting 2.57.
Add more cluster info to lvmdump
Add const attributes where possible, first cut.
Add more cluster info to lvmdump.
Add further const attributes throughout.
Add support for renaming mirrored LVs.
Factor out core of lvrename() to lv_rename lvm library function.

Add --mirrorlog argument to specify log type for mirrors.
Don't try to monitor devices which we failed to create.
Don't leak a file descriptor in fcntl_lock_file(), when fcntl fails.
Don't attempt to monitor devices if their creation failed in _lv_activate.
Don't leak a file descriptor in fcntl_lock_file() when fcntl fails.
Replace create_dir with dm_create_dir.
Detect stream write failure reliably; new fn: lvm_fclose; use dm_fclose
Detect stream write failure reliably with lvm_fclose using dm_fclose.
Fix clvmd if compiled with gulm support. (2.02.26)
Trivial fix to lvdisplay man page.
Fix lvdisplay man page to say LV size is reported in sectors, not KB.
Add vg_lock_and_read() external library function.
Fix loading of persistent cache if cache_dir is used. (2.02.23)
Eliminate uses of strdup+basename. Use last_path_component instead.
Reduce _compare_paths lstat error message from log_error to log_very_verbose.
Create util.h with last_path_component replacing strdup + basename.
Use gcc's printf attribute wherever possible.
In _line_append, use "sizeof buf - 1" rather than equivalent "4095"
In _line_append, use "sizeof buf - 1" rather than equivalent "4095".
Introduce is_same_inode macro, now including a comparison of st_dev.
Don't leak a file descriptor in _lock_file(), when flock fails.
Don't leak a file descriptor in _lock_file() when flock fails.
Add SUN's LDOM virtual block device (vdisk) and ps3disk to filters.
Split metadata-external.h out from metadata.h for the tools to use.

.TP
.I \-\-log disk/core
This optional argument switches the logging type of a
mirror. The logging type can be either "disk" (persistent)
or "core" (non-persistent). The default logging type is "disk".
.I \-\-mirrorlog {disk|core}
Specifies the type of log to use.
The default is disk, which is persistent and requires
a small amount of storage space, usually on a separate device
from the data being mirrored.
Core may be useful for short-lived mirrors: It means the mirror is
regenerated by copying the data from the first device again every
time the device is activated - perhaps, for example, after every reboot.
.TP
.I \-\-corelog
The optional argument "--corelog" is the same as specifying "--log core".

Specifying the optional argument --nosync will cause the creation
of the mirror to skip the initial resynchronization. Any data written

intensive initial sync of an empty device.
The optional argument "--log" gives the ability to specify the type
of mirror log to be used. The available types are "disk" and "core",
where "disk" is the default. The "disk" log is persistent and requires
a small amount of storage space - usually on a separate device from the
mirror devices. While the "disk" log may cause the mirror to be slightly
slower during writes, it prevents the need to completely resynchronize
the mirror upon each instantiation (e.g. a reboot).
