Instead of lumping all the exceptions, break them out to handle the dbus
exceptions separately, to reduce the amount of debug information that ends
up in the journal that has questionable value.
Lvm occasionally fails to return all the request JSON keys in the output of
"fullreport". This happens very rarely. When it does the daemon was reporting
the resulting informational exception:
MThreadRunner: exception
Traceback (most recent call last):
File "/usr/lib/python3.9/site-packages/lvmdbusd/utils.py", line 667, in _run
self.rc = self.f(*self.args)
File "/usr/lib/python3.9/site-packages/lvmdbusd/fetch.py", line 40, in _main_thread_load
(lv_changes, remove) = load_lvs(
File "/usr/lib/python3.9/site-packages/lvmdbusd/lv.py", line 143, in load_lvs
return common(
File "/usr/lib/python3.9/site-packages/lvmdbusd/loader.py", line 37, in common
objects = retrieve(search_keys, cache_refresh=False)
File "/usr/lib/python3.9/site-packages/lvmdbusd/lv.py", line 95, in lvs_state_retrieve
l['vdo_operating_mode'],
KeyError: 'vdo_operating_mode'
The daemon retries the operation, which usually works and the daemon continues.
However, simply reporting this informational stack trace is causing CI and other
automated tests to fail as they expect no tracebacks in the log output.
Remove the reporting of this code path unless it persists and causes the daemon
to give up and exit.

When the daemon isn't started with --debug we will keep a circular
buffer of the past N number of debug messages which we will output
when we encounter an issue.
Rather than trying to bubble up return codes that get us to exit cleanly
it's better to just raise an exception to bail. In some cases functions
don't have return codes, so they cannot be checked.
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.
Depending on when an occurs, it maynot have any information available for
lastlog. In this case try to grab an error message from the original
response.
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.
in vgcreate for shared sanlock vg, if sanlock_write_resource
returns an unexpected error, then make init_vg_sanlock fail
which will cause the vgcreate to fail.
When storage is lost under a sanlock VG, and kill_vg/drop_vg
are used, sanlock_rem_lockspace() may return an error, but
the cleanup steps should still be performed. Without the
cleanup, gl_lsname_sanlock was not cleared. This caused
future lock requests to fail with ENOLS, but the NO_GL_LS
flag was not set due to gl_lsname_sanlock being set.
This caused lockd_global(sh) in lvm commands to fail when
they could succeed.
Fix from guozhonghua216
'.ID_FS_TYPE_NEW' is a custom property added by an LVM UDev rule
which is now being removed and 'ID_FS_TYPE' has the same value.

Analyzer here was rather confused about possiblity of loosing previously
assigned device pointers - fixed by passing zero initialize memory
before first assign.
