WHATS_NEW
View File

@ -6,7 +6,7 @@ Version 2.02.107 -
Add -S/--select to pvs,vgs,lvs and {pv,vg,lv}display -C for report selection.
Use dm_report_init_with_selection now, implicit "selected" field appears.
Make use of libdm's DM_REPORT_FIELD_TYPE{SIZE,PERCENT,STRING_LIST} for fields.
Add support for all-or-nothing (atomic) pvmove.
Support all-or-nothing pvmove --atomic.
Automatically add snapshot metadata size for -l %ORIGIN calculation.
When converting RAID origin to cache LV, properly rename sub-LVs.
Use RemoveOnStop for lvm2-lvmetad.socket systemd unit.
