Log message:
Update vg_remove_single_* functions to use the removed_pvs list.
Now that we've split vg_remove_single into two routines, in the first routine
that only manipulates memory, we move the PVs from the vg->pvs list to the
vg->removed_pvs list. Then later, we iterate through this list to write the
removed PVs to disk, which removes them from the volume group and places them
into the internal ORPHAN VG.

Log message:
Cleanup fid finalization code in free_vg and allow exactly the same fid to be set again for a PV/VG.
Actually, we can call vg_set_fid(vg, NULL) instead of calling
destroy_instance for all PV structs and a VG struct - it's the same
code we already have in the vg_set_fid.
Also, allow exactly the same fid to be set again for the same PV/VG
Before, this could end up with the fid destroyed because we destroyed
existing fid first and then we used the new one and we didn't care
whether existing one == new one by chance.

Log message:
Use created hash tables for quick check of LV, PV.
Instead of searching linear list of all LVs, PVs - use created hash tables
also for quick mapping between LV.
(Note - for small number of PVs or LVs the overhead of the hash is bigger).
TODO: Use hash tables in volume_group structure directly.

Log message:
Update check in vg_split_mdas to account for ignored mdas list.
The check in vg_split_mdas will trigger an error if the 'from' vg
list is empty. However, this might be ok in some instances now
that we have ignored mdas. Relax this check so an error is triggered
only in the case where there's truly no more mdas in the 'from'
vg.
One example of where this makes a difference is with vgreduce.
If we try to vgreduce a PV with un-ignored mdas, this should trigger
the balancing function to un-ignore mdas on another PV in the VG.
However, we don't get to vg_write() before we fail because this
list size check fails, and we see an error message indicating:
"Cannot remove final metadata area ..."
Another example is with vgsplit into a new VG, where the PVs
being moved contain all ignored mdas. We must move the mdas on
fid->metadata_areas_ignored from 'vg_from' to 'vg_to'.

Ensure fid mda lists are populated correctly during vgextend.
The vgextend path calls add_pv_to_vg(). Inside add_pv_to_vg(),
we must ensure we pass the correct mdas list into pv_setup(), as
copies of mdas are placed on the vg->fid list. If we don't place
the mdas on the correct vg->fid list, the various counts may be
incorrect and the metadata balance algorithm will not work when
called from vg_write() path.

Log message:
Before committing each mda, arrange mdas so ignored mdas get committed first.
Arrange mdas so mdas that are to be ignored come first. This is an
optimization that ensures consistency on disk for the longest period of time.
This was noted by agk in review of the v4 patchset of pvchange-based mda
balance.
Note the following example for an explanation of the background:
Assume the initial state on disk is as follows:
PV0 (v1, non-ignored)
PV1 (v1, non-ignored)
PV2 (v1, non-ignored)
PV3 (v1, non-ignored)
If we did not sort the list, we would have a commit sequence something like
this:
PV0 (v2, non-ignored)
PV1 (v2, ignored)
PV2 (v2, ignored)
PV3 (v2, non-ignored)
After the commit of PV0's mdas, we'd have an on-disk state like this:
PV0 (v2, non-ignored)
PV1 (v1, non-ignored)
PV2 (v1, non-ignored)
PV3 (v1, non-ignored)
This is an inconsistent state of the disk. If the machine fails, the next
time it was brought back up, the auto-correct mechanism in vg_read would
update the metadata on PV1-PV3. However, if possible we try to avoid
inconsistent on-disk states. Clearly, because we did not sort, we have
a greater chance of on-disk inconsistency - from the time the commit of
PV0 is complete until the time PV3 is complete.
We could improve the amount of time the on-disk state is consistent by simply
sorting the commit order as follows:
PV1 (v2, ignored)
PV2 (v2, ignored)
PV0 (v2, non-ignored)
PV3 (v2, non-ignored)
Thus, after the first PV is committed (in this case PV1), on-disk we would
have:
PV0 (v1, non-ignored)
PV1 (v2, ignored)
PV2 (v1, non-ignored)
PV3 (v1, non-ignored)
This is clearly a consistent state. PV1 will be read but the mda will be
ignored. All other PVs contain v1 metadata, and no auto-correct will be
required. In fact, if we commit all PVs with ignored mdas first, we'll
only have an inconsistent state when we start writing non-ignored PVs,
and thus the chances we'll get an inconsistent state on disk is much
less with the sorted method.

Log message:
Check for duplicate paths (pvids) on the commandline of vgcreate.
A user specifying duplicate paths on the cmdline of vgcreate will
get a message similar to the following:
vgcreate vgtest2 /dev/loop3 /dev/loop5
Found duplicate PV jk1lXsKzwyOKlXq6bhaFFKMQQ06oPgu8: using /dev/loop5 not /dev/loop3
Found duplicate PV jk1lXsKzwyOKlXq6bhaFFKMQQ06oPgu8: using /dev/loop3 not /dev/loop5
Internal error: Duplicate PV id jk1lXs-Kzwy-OKlX-q6bh-aFFK-MQQ0-6oPgu8 detected for /dev/loop3 in vgtest2.
This is caught by vg_validate(), but it would be good to find
this condition earlier in the vgcreate code. add_pv_to_vg()
currently checks by pvname, but does not look for duplcate pvids.
This patch adds the check for duplicate pvids and results in new
error output as follows:
vgcreate vgtest2 /dev/loop3 /dev/loop5
Found duplicate PV jk1lXsKzwyOKlXq6bhaFFKMQQ06oPgu8: using /dev/loop5 not /dev/loop3

In add_pv_to_vg(), we should only add the pv to vg->pvs after all
internal checks have passed. The check for vg->extent_count exeeding
maximum was after we added the pv to the list, so this function could
return a state of vg->pvs that did not reflect other parameters such

Add dm_pool_strdup to allocate memory and copy a tag in {lv|vg}_change_tag()
We need to allocate memory for the tag and copy the tag value before we
add it to the list of tags. We could put this inside lvm2app since the
tools keep their memory around until vg_write/vg_commit is called, but
we put it inside the internal library to minimize code in lvm2app.
We need to copy the tag passed in by the caller to ensure the lifetime of
the memory until the {vg|lv} handle is released.

Remove useless memory allocation for pv->vg_name in _alloc_pv().
All this seems to do is provide a memory leak so remove it.
The only caller of _alloc_pv() later explicitly sets
pv->vg_name = fmt->orphan_vg_name so clearly this allocation
should be removed. I also saw no where in the code where
strncpy was used to assign pv->vg_name - only direct assignments
and strdup's.

Log message:
Add pvcreate_params to vg_extend_single_pv.
Should be no functional change. If this parameter is set to NULL, just fail
the extend if the device is not already a PV. If non-NULL, try pvcreate_single
before failing. Note that pvcreate_single() handles the log_error in case
of failure so we just return 0 if pvcreate_single() fails.

Log message:
In the new _vg_read_for_update(), we always do the check for CLUSTERED vg
status flag after reading the volume group. Thus, no need to set the flag
in vg_read() or clear it later before calling _vg_bad_status_bits().
Also, add back in the !lockingfailed() as part of the CLUSTERED flag check.
It's unclear why it was removed when the check was moved from
_vg_bad_status_bits() to inside _vg_lock_and_read().
There was an open question about the last check in the 'if' stmt for
lockingfailed() with a previous patch submitted. However, I would
defer that right now as it is a separate item and this patch should
be no functional change by including the !lockingfailed().
Petr acked this patch on 5/26 I just forgot to check it in.
