Does lvremove, vgremove, pvremove issue discard (eg. TRIM) commands
in order to release LE/PE/metadata blocks from the underlying devices (SSD) ?
If LVM don't do it now, is it a planned feature ?
Meanwhile, which methods can be used to discard/TRIM blocks when removing
a LV, or a VG, or PV, without wiping the complete underlying device.
Something to feed hdparm --trim-sector-ranges once the LV, VG or PV is
removed for example ?
