Troubleshooting Ceph on Windows
|
|
===============================
|
|
|
|
MSI installer
|
|
~~~~~~~~~~~~~
|
|
|
|
The MSI source code can be consulted here:
|
|
https://github.com/cloudbase/ceph-windows-installer
|
|
|
|
The following command can be used to generate MSI logs
|
|
|
|
.. code:: PowerShell
|
|
|
|
msiexec.exe /i $msi_full_path /l*v! $log_file
|
|
|
|
WNBD driver installation failures will be logged here: ``C:\Windows\inf\setupapi.dev.log``.
|
|
A server reboot is required after uninstalling the driver, otherwise subsequent
|
|
install attempts may fail.
|
|
|
|
Wnbd
|
|
~~~~
|
|
|
|
For ``WNBD`` troubleshooting, please check this page: https://github.com/cloudbase/wnbd#troubleshooting
|
|
|
|
Privileges
|
|
~~~~~~~~~~
|
|
|
|
Most ``rbd-wnbd`` and ``rbd device`` commands require privileged rights. Make
|
|
sure to use an elevated PowerShell or CMD command prompt.
|
|
|
|
Crash dumps
|
|
~~~~~~~~~~~
|
|
|
|
Userspace crash dumps can be placed at a configurable location and enabled for all
|
|
applications or just predefined ones, as outlined here:
|
|
https://docs.microsoft.com/en-us/windows/win32/wer/collecting-user-mode-dumps.
|
|
|
|
Whenever a Windows application crashes, an event will be submitted to the ``Application``
|
|
Windows Event Log, having Event ID 1000. The entry will also include the process id,
|
|
the faulting module name and path as well as the exception code.
|
|
|
|
Please note that in order to analyze crash dumps, the debug symbols are required.
|
|
We're currently building Ceph using ``MinGW``, so by default ``DWARF`` symbols will
|
|
be embedded in the binaries. ``windbg`` does not support such symbols but ``gdb``
|
|
can be used.
|
|
|
|
``gdb`` can debug running Windows processes but it cannot open Windows minidumps.
|
|
The following ``gdb`` fork may be used until this functionality is merged upstream:
|
|
https://github.com/ssbssa/gdb/releases. As an alternative, ``DWARF`` symbols
|
|
can be converted using ``cv2pdb`` but be aware that this tool has limited C++
|
|
support.
|
|
|
|
ceph tool
|
|
~~~~~~~~~
|
|
|
|
The ``ceph`` Python tool can't be used on Windows natively yet. With minor
|
|
changes it may run, but the main issue is that Python doesn't currently allow
|
|
using ``AF_UNIX`` on Windows: https://bugs.python.org/issue33408
|
|
|
|
As an alternative, the ``ceph`` tool can be used through Windows Subsystem
|
|
for Linux (WSL). For example, running Windows RBD daemons may be contacted by
|
|
using:
|
|
|
|
.. code:: bash
|
|
|
|
ceph daemon /mnt/c/ProgramData/ceph/out/ceph-client.admin.61436.1209215304.asok help
|
|
|
|
IO counters
|
|
~~~~~~~~~~~
|
|
|
|
Along with the standard RBD perf counters, the ``libwnbd`` IO counters may be
|
|
retrieved using:
|
|
|
|
.. code:: PowerShell
|
|
|
|
rbd-wnbd stats $imageName
|
|
|
|
At the same time, WNBD driver counters can be fetched using:
|
|
|
|
.. code:: PowerShell
|
|
|
|
wnbd-client stats $mappingId
|
|
|
|
Note that the ``wnbd-client`` mapping identifier will be the full RBD image spec
|
|
(the ``device`` column of the ``rbd device list`` output).
|
|
|
|
Missing libraries
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
The Ceph tools can silently exit with a -1073741515 return code if one of the
|
|
required DLLs is missing or unsupported.
|
|
|
|
The `Dependency Walker`_ tool can be used to determine the missing library.
