- Subject: [dm-devel] [PATCH] (4/4) LVM2 to use dm_report
- Date: Fri, 12 Jan 2007 18:32:09 -0500
Hi,
This patch makes LVM2 to use dm_report in libdevmapper
instead of its lib/report functions.
Tested following commands where LVs of linear, striped, mirrored
and snapshot exist and confirmed the output is same with the
original LVM2 2.02.17.
lvs
pvs
vgs
lvs -a
pvs -a
lvs -a -o +devices
lvs -o name,name,lv_name,vg_name
lvs -a -o name,name,lv_name,vg_name
lvs -a -o name,lv_name,vg_name -O name
lvs -a -o name,lv_name,vg_name -O -name
lvs -a -o name,lv_name,vg_name -O size
lvs -a -o name,lv_name,vg_name -O lv_size
lvs -a -o name,lv_name,vg_name -O -size
pvs -o +pe_alloc_count,used,dev_size
pvs -a -o +pe_alloc_count,used,dev_size
Thanks,

Replaces lib/report by dm_report API in libdevmapper.
