system_id: detect an lvm1 system id
Detect an lvm1 system id by looking at the WRITE_LOCKED flag. Don't copy this lvm1 system id into vg->system_id so that the restrictions associated with the new system id are not applied to the old VG with the inherited lvm1 system id. --- lib/format_text/import_vsn1.c | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-)
