629efc6a89 Export lvm_pv_get_size(), lvm_pv_get_free(), lvm_pv_get_dev_size in lvm2app. 
We add these exports to show the pv_size and pv_free and dev_size
fields.
Fixes rhbz561423.

c79b425135 Add snapshot merge wrappers to abstract the associations and flags used 
to represent merging origin and snapshot volumes.

Mike Snitzer
c582e3c039 Merge on activate support. 
If either the origin or snapshot that is to be merged is open the merge
will not start; only the merge metadata will be written.  The merge will
start on the next activation of the origin (or via lvchange --refresh)
IFF both the origin and snapshot are closed.

Merge on activate is particularly important if we want to merge over a
mounted filesystem that cannot be unmounted (until next boot) --- for
example root.

c45af88a83 When there is merging snapshot, report percentage on the origin LV. 
Because the snapshot LV will be hidden this is needed so the user can
see merging progress with "lvs" command.

3b6a076e1e Report merging snapshot as 'S' instead of 's': 
This is useful for when the snapshot is still active and merging hasn't
started yet; it shows a merge is pending.  Once merging starts the
merging snapshot will be hidden but can still be displayed with 'lvs -a'

Report snapshot origin with merging snapshot as 'O' instead of 'o':
Before merge starts this shows that a merge is pending.  While merging
the snapshot will be hidden, 'O' enables a user to see that there is a
snapshot merging.

68fac97a07 Add vg_is_resizeable() and cleanup references. 
Clean up VG_RESIZEABLE flag by creating vg_is_resizeable().
Update comment - we no longer have ALLOW_RESIZEABLE.
Also use vg_is_exported() in one place missed by earlier patch.
Should be no functional change.
 2009-09-15 18:35:13 +00:00
Dave Wysochanski
905240f91d Use vg_is_exported(vg) macro everywhere. 
This patch is all just cleanup and no other patch depends on it.
Replace explicit dereference and check with vg_is_exported().
Update a few copyrights and remove unnecessary whitespace.
Should be no functional change.

483a7cb6d5 Refactor a few report field calculations into separate functions. 
For liblvm 'get' functions, we should share code with the reporting functions.
This means we need common code to return the values for the fields.
In this patch we refactor a few of the fields needed in liblvm.
Unfortunately, for the simple fields that do derefernces of structure
members (for example, vg_extent_count), we cannot call the common function
from the reporting infrastructure without more refactoring.  The reason is
that the dereference of the simple fields is done deep inside the reporting
code (to get the generic "data" pointer), and the display function is a
generic 'size32' function.  We can fix these issues later with more
refactoring.

Should be no functional change and the testsuite should cover any possible
regressions.  The only fields in the report affected by this patch are:
vg_size, vg_free, and pv_mda_count.

Milan Broz
afd9ba98c1 Merge lv_is_displayable and lv_is_visible. 
Displayable and visible is the same thing.

volumes_count(vg) is now vg_visible_lvs() and always
returns number of LVs from user perspective.
 2009-05-13 21:27:43 +00:00

87f42fda5e Add sparse devices: lvcreate -s --virtualoriginsize (hidden zero origin). 
Add lvs origin_size field.
Fix linux configure --enable-debug to exclude -O2.

Still a few rough edges, but hopefully usable now:
  lvcreate -s vg1 -L 100M --virtualoriginsize 1T

83d026861c pe_start can be overwritten in VG metadata, so it is not PV label-only field. 2009-02-25 23:31:06 +00:00
Milan Broz
ea0cdd28c1 Separate PV label attributes which do not need parse metadata when reporting. 
When reporting explicitly label attributes (pv_uuid for example), we do not
need to read metadata.

This patch separate the label fileds and removes scan_vgs_for_pvs
in process_each_pv() if not needed.

(There should be no user visible change in output.)

Dave Wysochanski
2815870302 Fix pvs segfault when run with orphan PV and vg_mda_size or vg_mda_free fields 
We display '0' for these fields now in this case.  Ideally these values are
undefined for an orphan PV but today there is no way to specify undefined
with display functions such as _size64_disp().
 2009-01-10 15:04:28 +00:00
Dave Wysochanski
e9f57f2beb Add pv_mda_size to 'pvs' and vg_mda_size to 'vgs'. 
Reports the size of the smallest metadata area in a PV or a VG.
Useful to confirm pvcreate --metadatasize or pvmetadatasize setting in
/etc/lvm/lvm.conf file.

NOTE: Actual value in these fields will most always differ from that
given in pvcreate options due to rounding and alignment effects.

539f903fd2 Fix segfault when invalid field given in reporting commands. 
Problem is dm_report_init() may return NULL and subsequent call to
dm_report_set_output_field_name_prefix() doesn't handle NULL value.

Example:
	pvs --nameprefixes --rows --unquoted --noheadings -opv_name,fred
  Logical Volume Fields
  ---------------------
    lv_uuid              - Unique identifier
    lv_name              - Name.  LVs created for internal use are enclosed in brackets.
 ...

  Physical Volume Segment Fields
  ------------------------------
    pvseg_start          - Physical Extent number of start of segment.
    pvseg_size           - Number of extents in segment.

  Unrecognised field: fred
