==================================
|
||||
Improve man page style for fsadm, lvreduce, lvremove, lvrename, lvresize.
|
||||
Support break for vgchange and vgrefresh operation.
|
||||
Switch int to unsigned type for pvmetadatacopies for pv_create().
|
||||
Replace :space: with [\t ] for awk in vgimportclone (not widely supported).
