The idea of using 'eprefix' unfortunatelly fails on /usr moved distros.
But there is also default --sysconfdir which is normaly set to /etc.
If unset it's PREFIX/etc.
For now revert.
FIXME: replace lvm vars with standard ones everyone is using.
Document following items:
configuration cascade (man lvm.conf)
--profile ProfileName (man lvm)
--detachprofile (man vgchange/lvchange)
-o vg_profile/lv_profile (man vgs/lvs)
Also document --config a bit so we can see where it fits in the
configuration cascade - will be documented more in following commit...
Fix and improve handling on sigint.
Always check for signal presence *before* calling of command,
so it will not call the command when break was hit.
If the command has been finished succesfully there is
no problem to mark the command ok and not report interrupt at all.
Fix cuple related stack; reports and assignments.
Seems like we have a bit overcomplicated set of options
for deducing individual install dirs.
This patch fixes installation issues with DESTDIR,
but the whole set of configure options should be simplified.
Create/remove PV
Create/remove snapshots (old type & thin)
PV lookups based on name and UUID
PV resize
Signed-off-by: Tony Asleson <tasleson@redhat.com>
The pv resize code required that a lvm_vg_write be done
to commit the change. When the method to add the ability
to list all PVs, including ones that are not assocated with
a VG we had no way for the user to make the change persistent.
Thus additional resize code was move and now liblvm calls into
a resize function that does indeed write the changes out, thus
not requiring the user to explicitly write out he changes.

After the last rebase, existing unit test case was
run which uncovered a number of errors that required
attention.
Uninitialized variables and changes to type of numeric
return type were addressed.

Code move and changes to support calling code from
command line and from library interface.
V2 Change lock_vol call
Signed-off-by: Tony Asleson <tasleson@redhat.com>
As locks are held, you need to call the included function
to release the memory and locks when done transversing the
list of physical volumes.
V2: Rebase fix
V3: Prevent VGs from getting cached and then write protected.

Simplified version of lv resize.
v3: Rebase changes to make work. Needed to set sizeargs = 1
to indicate to resize that we are asking for a size based
resize.
Signed-off-by: Tony Asleson <tasleson@redhat.com>
Extend the lv resize parameter structure to contain everything
the re-size functions need so that the command line does not
need to be present for lower level calls when we call from
library functions.

Add thin and thin pool lv creation support to lvm library
This is Mohan's thinp patch, re-worked to include suggestions
from Zdenek and Mohan.
V2: Remove const lvm_lv_params_create_thin
Add const lvm_lv_params_skip_zero_get
V3: Changed get/set to use generic functions like current
property
V4: Corrected macro in properties.c
V5: Fixed a bug in liblvm/lvm_lv.c function lvm_lv_create.
incorrectly used pool instead of lv_name when doing the
find_lv_in_vg call.

These settins are customizable by profiles:
allocation/thin_pool_zero
allocation/thin_pool_discards
allocation/thin_pool_chunk_size
activation/thin_pool_autoextend_threshold
activation/thin_pool_autoextend_percent
Besides the classical configuration checks (type checking and
checking whether the item is recognized by lvm tools) for profiles,
do an extra check whether the configuration setting is customizable
by a profile at all. Give a warning message if not.
Before, the status of the configuration check (config_def_check fn call)
was saved directly in global configuration definitinion array (as part
of the cfg_def_item_t/flags)
This patch introduces the "struct cft_check_handle" that defines
configuration check parameters as well as separate place to store
the status (status here means CFG_USED and CFG_VALID flags, formerly
saved in cfg_def_item_t/flags). This struct can hold config check
parameters as well as the status for each config tree separately,
thus making it possible to run several instances of config_def_check
without interference.
Just to make it more clear and also not to confuse
config_valid with check against config definition
(and its 'valid' flag within the config defintion tree).
The command to change the profile for existing VG/LV:
"vgchange/lvchange --profile <profile_name>"
The command to detach any existing profile from VG/LV:
"vgchange/lvchange --detachprofile"
If "vgcreate/lvcreate --profile <profile_name>" is used, the profile
name is automatically stored in metadata for making it possible to
load it automatically next time the VG/LV is used.
