cfc87157a4 lvmdbusd: Make sure to set cfg.got_external_event
We were incorrectly only setting this if --udev wasn't present on the
command line.  In all cases when we see a manager.ExternalEvent we want
to set this.

05f7fa5a85 lvmdbusd: Re-work flight recorder data
Introduce a new lock for the flight recorder, so that we can dump it when
a command is block waiting for lvm to complete.  Also in all paths we will
addthe metadata to the flight recorder before it's done, so we will have
it when a command hangs and we dump the flight recorder. Add the missing
bits after the command has finished.

Cleaned up the output too.

ea45ba753e lvmdbustest: Remove force exception in _wait_for_job
We put this in to test one of the paths in the damon, but unfortunately
if we hit the race condition where the job actually is done we will try
to call j.Wait(1) after the remove.  This fails with:

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod:
Method "Wait" with signature "i" on interface "com.redhat.lvmdbus1.Job"
doesn't exist

Which is caused by the dbus object no longer existing.  We could handle
this, but the issue is we no longer have the ability to get the result to
return, they have been lost.

A better solution would be to write a specific unit test to force this code
path and handle all the possible outcomes.

0887896847 vgremove: remove online files in run dir
These files are automatically cleared on reboot given
that /run is tmpfs, and that remains the primary way
of clearing online files.

But, if there's extreme use of vgcreate+pvscan+vgremove
between reboots, then removing online files in vgremove
will limit the number of unused online files using space
in /run.

264827cb98 lvresize: add new options and defaults for fs handling
The new option "--fs String" for lvresize/lvreduce/lvextend
controls the handling of file systems before/after resizing
the LV.  --resizefs is the same as --fs resize.

The new option "--fsmode String" can be used to control
mounting and unmounting of the fs during resizing.

Possible --fs values:

checksize
  Only applies to reducing size; does nothing for extend.
  Check the fs size and reduce the LV if the fs is not using
  the affected space, i.e. the fs does not need to be shrunk.
  Fail the command without reducing the fs or LV if the fs is
  using the affected space.

resize
  Resize the fs using the fs-specific resize command.
  This may include mounting, unmounting, or running fsck.
  See --fsmode to control mounting behavior, and --nofsck to
  disable fsck.

resize_fsadm
  Use the old method of calling fsadm to handle the fs
  (deprecated.) Warning: this option does not prevent lvreduce
  from destroying file systems that are unmounted (or mounted
  if prompts are skipped.)

ignore
  Resize the LV without checking for or handling a file system.
  Warning: using ignore when reducing the LV size may destroy the
  file system.

Possible --fsmode values:

manage
  Mount or unmount the fs as needed to resize the fs,
  and attempt to restore the original mount state at the end.

nochange
  Do not mount or unmount the fs. If mounting or unmounting
  is required to resize the fs, then do not resize the fs or
  the LV and fail the command.

offline
  Unmount the fs if it is mounted, and resize the fs while it
  is unmounted. If mounting is required to resize the fs,
  then do not resize the fs or the LV and fail the command.

Notes on lvreduce:

When no --fs or --resizefs option is specified:
. lvextend default behavior is fs ignore.
. lvreduce default behavior is fs checksize
  (includes activating the LV.)

With the exception of --fs resize_fsadm|ignore, lvreduce requires
the recent libblkid fields FSLASTBLOCK and FSBLOCKSIZE.
FSLASTBLOCK*FSBLOCKSIZE is the last byte used by the fs on the LV,
which determines if reducing the fs is necessary.

b869a6ff7a fix fs block size detection
blkid_get_tag_value() is not a reliable way to query the fs
BLOCK_SIZE, so use the "probe" functions instead.

973d0bd5b7 report: fix lv_active column type from STR to BIN
Fix lv_active to be of BIN type instead of STR. This allows lv_active to
follow the report/binary_values_as_numeric setting as well as --binary
cmd line switch. Also, it makes it possible to use -S|--select with
either textual or numeric representation of the value, like 'lvs -S
active=active' but also 'lvs -S active=1'.

0eebd9d780 vgimportdevices: fix locking when creating devices file

3c49a2e43c vgimportdevices: change result when devices are not added
When using --all, if one VG is skipped, continue adding
other VGs, and do not return an error from the command
if some VGs are added. (A VG is skipped if it's missing PVs.)

If the command fails during devices file setup or device
scanning, then remove the devices file if it has been
newly created by the command, and exit with an error.

If devices from a named VG are not imported (e.g. the
VG is missing devices), then remove the devices file if
it has been newly created by the command, and exit with
an error.

If --all VGs are being imported, and no devices are found
to include in the devices file, then remove the devices
file if it has been newly created by the command, and
exit with an error.
