Accept -q as the short form of --quiet.
Suppress non-essential standard output if -q is given twice.
Treat log/silent in lvm.conf as equivalent to -qq.
Review all log_print messages and change some to
log_print_unless_silent.
When silent, the following commands still produce output:
dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay,
pvs, version, vgcfgrestore -l, vgdisplay, vgs.
[Needs checking.]
Non-essential messages are shifted from log level 4 to log level 5
for syslog and lvm2_log_fn purposes.
leaving behind the LVM-specific parts of the code (convenience wrappers that
handle `struct device` and `struct cmd_context`, basically). A number of
functions have been renamed (in addition to getting a dm_ prefix) -- namely,
all of the config interface now has a dm_config_ prefix.
Move the free_vg() to vg.c and replace free_vg with release_vg
and make the _free_vg internal.
Patch is needed for sharing VG in vginfo cache so the release_vg function name
is a better fit here.
We allow writing non-orphan PVs only for resize now. The "orphan PV" assert
in pv_write fn uses the "allow_non_orphan" parameter to control this assert.
However, we should find a more elaborate solution so we can remove this
restriction altogether (pv_write together with vg_write is not atomic, we
need to find a safe mechanism so there's an easy revert possible in case of
an error).
When using vgmetadatacopies value other than "umanaged" (0), prompt
the user if the usage of --metadataignore would change the value of
vgmetadatacopies. The main 2 cases are:
1) pvchange --metadataignore
2) vgextend --metadataignore
We leave the prompt check in the tools, and do not change anything
if the user says 'n'.
Examples:
vgextend --metadataignore y vgtest /dev/loop0
Setting metadataignore will override preferred number of copies of VG vgtest metadata.
Are you sure? [y/n]: y
No physical volume label read from /dev/loop0
Physical volume "/dev/loop0" successfully created
Volume group "vgtest" successfully extended
pvchange --metadataignore y /dev/loop3
Setting metadataignore on /dev/loop3 will override preferred number of copies of VG vgtest metadata.
Are you sure? [y/n]: y
WARNING: Changing preferred number of copies of VG vgtest metadata from 3 to 2
Physical volume "/dev/loop3" changed
1 physical volume changed / 0 physical volumes not changed

In preparation to call this from both pvcreate as well as pvchange,
move the guts of metadataignore into a library function.

When a user explicitly sets a new mda ignore value for a PV, we
should update vg_mda_copies accordingly. When the VG is written
out, the user would not want the new ignore state to get lost as
a result of the vg_mda_copies value and logic in the vg_write
path.

This patch just modifies pvchange to call the underlying ignore
functions for mdas. Ensure special cases do not reflect changes
in metadata (PVs with 0 mdas, setting ignored when already ignored,
clearing ignored when not ignored).

Earlier patches added some infrastructure to lookup a vgname from
a pvname. We now can cleanup some of the pvchange and other code
by requiring callers that want to modify some pv property:
1) lookup the vgname by the pvname
2) use the vgname to obtain a vg handle
3) get the pv handle from the vg handle
This should work going forward and be a much cleaner interface,
as we move away from pvs as standalone objects.
Fix vg_read() error paths to properly release upon vg_read_error().
Note that in the iterator paths (process_each_*()), we release
inside the iterator so no individual cleanup is needed. However there
are a number of other places we missed the cleanup. Proper cleanup
when vg_read_error() is true should be calling vg_release(vg), since
there should be no locks held if we get an error (except in certain
special cases, which IMO we should work to remove from the code).
Unfortunately the testsuite is unable to detect these types of memory
leaks. Most of them can be easily seen if you try an operation
(e.g. lvcreate) with a volume group that does not exist. Error
message looks like this:
Volume group "vg2" not found
You have a memory leak (not released memory pool):

Fix missing VG unlocks in some pvchange error paths.
Add some missing validation of VG names.
Rename validate_vg_name() to validate_new_vg_name().
Change orphan lock to VG_ORPHANS.
Change format1 to use ORPHAN as orphan VG name.
