The segs
, data_lvs
, and metadata_lvs
fields are only filled by a
call to bd_lvm_lvinfo_tree or bd_lvm_lvs_tree. They are all NULL
normally. If they are filled, they follow these rules:
A LV is either stored directly on physical volumes, or is made up
of sub-LVs. If it is stored on PVs, the segs
list is non-empty
and the data_lvs
and metadata_lvs
fields are both NULL. If it is
made up of sub-LVs, then segs
is NULL, data_lvs
is non-empty and
metadata_lvs
might or might not be empty but is non-NULL. The
sub-LVs contained in data_lv
and metadata_lv
are always included
in data_lvs
and metadata_lvs
, respectively.
For a partial LV, the segs
list might not be complete; i.e., the
sum of the sizes of the listed segments might not be equal to the
size reported for the LV itself.
Also, the order of entries in segs
must be assumed to be random;
it does not correspond to the order of segements in the logical
volume itself.
