to use a different set of variables to decide on whole devices

Now, we use ID_PART_TABLE_TYPE to detect that there's something

instead to decide between whole device (DEVTYPE="disk") and partition

Instead, there's going to be a new field "seg_le_ranges" which
is going to replace the seg_pe_ranges and it will mark hidden devices -
this is going to be introduced in a patch later.

So in the end we'll end up with:

   (LV segment's devices)
   devices field with "device_name(extent_start)" format, not marking hidden devices
   seg_pe_ranges field with "device_name:extent_start-extent_end" format, not marking hidden devices (deprecated, new seg_le_ranges should be used instead for standardized format)
   seg_le_ranges field with "device_name:extent_start-extent_end" format, marking hidden devices

   (LV segment's metadata devices)
   metadata_devices field with "device_name:extent_start-extent_end" format, not marking hidden devices
   seg_metadata_le_ranges field with "device_name:extent_start-extent_end" format, marking hidden devices

Also, both seg_le_ranges and seg_metadata_le_ranges will honour the
report/list_item_separator setting which can be used to configure
the delimiter used for list items.

So, to sum it up, we will recommend using the new seg_le_ranges and
seg_metadata_le_ranges fields because they display devices with
standard extent range format, they can mark hidden devices and they
honour the report/list_item_separator setting.

We'll be keeping devices,seg_pe_ranges and metadata_devices fields
for compatibility.

8 years agotoollib: add comment about missing device
David Teigland [Mon, 18 Jan 2016 21:40:42 +0000 (15:40 -0600)]
toollib: add comment about missing device

Add a comment in _process_pvs_in_vg() to document the
place where there have been problems with processing
PVs twice.

For a while we had a hacky workaround here where we'd
skip processing a PV if its device wasn't found in
all_devices (and !is_missing_pv since we want to
process PVs with missing devices.).  That workaround
was removed in commit 5cd4d46f because it was no
longer needed.

The workaround had originally been needed to prevent
a device from being processed twice when the PV had
no MDAs -- it would be processed once in its real VG
and then the workaround would prevent it from being
processed a second time in the orphan VG.

Wrongly appearing as an orphan likely happened because
lvmcache would consider the no-MDA PV an orphan unless
the real VG holding that PV was also in lvmcache.
This issue is also mentioned in pvchange where holding
the global lock allows VGs to remain in lvmcache so
PVs with 0 mdas are not considered orphans.

The workaround in _process_pvs_in_vg() was originally
intended for reporting commands, not for pvchange.
But, it was accidentally helping pvchange also because
the method described by the pvchange global lock
comment had been subverted by commit 80f4b4b8.
Commit 80f4b4b8 was found to be unnecessary, and was
reverted in commit e710bac0.  This restored the
intended global lock lvmcache effect to pvchange, and
it no longer relied on the workaround in toollib.

David Teigland [Tue, 12 Jan 2016 20:57:52 +0000 (14:57 -0600)]
pvmove: use toollib

Previously, pvmove used the function find_pv_in_vg() which did the
equivalent of process_each_pv() by doing:

  find_pv_by_name() -> get_pvs() ->

  get_pvs_internal() -> _get_pvs() -> get_vgids() ->

  /* equivalent to process_each_pv */
  dm_list_iterate_items(vgids)
    vg = vg_read_internal()
    dm_list_iterate_items(&vg->pvs)

With the found 'pv', it would do vg_read() on pv_vg_name(pv),
and then do the actual pvmove processing.

This commit simplifies by using process_each_pv() and putting
the actual pvmove processing into the "single" function.
This eliminates both find_pv_by_name() and the vg_read().
The processing code that followed vg_read remains the same.

The return code for the pvmove command is not based on the
process_each_pv return code, but is based on the success/fail
conditions in the existing code.
