CheckMK Raw in k8s with CIFS / NFS

[eizieizi]

Hi guys,

what kind of storage do you guys use for the PV? I was trying to use NFS with a PV which did not work because redis was not able to start properly. (before i had to configure an emptydir for the tmpfs because there were a lot of Bad Filetype errors...)

I tried to further isolate the problem and mounted the NFS Server directly on the worker nodes and published the NFS Volume via hostPath into the container. Same error, redis did not start well (it is running, but if you do an omd restart you see errors)

I also tried the same via CIFS and hostPath but there im facing the following issue

Traceback (most recent call last):
  File "/usr/bin/omd", line 60, in <module>
    omdlib.main.main()
  File "/omd/versions/2.0.0p12.cre/lib/python3/omdlib/main.py", line 4009, in main
    command.handler(version_info, site, global_opts, args, command_options)
  File "/omd/versions/2.0.0p12.cre/lib/python3/omdlib/main.py", line 1827, in main_create
    admin_password = init_site(version_info, site, global_opts, config_settings, options)
  File "/omd/versions/2.0.0p12.cre/lib/python3/omdlib/main.py", line 1895, in init_site
    create_version_symlink(site, omdlib.__version__)
  File "/omd/versions/2.0.0p12.cre/lib/python3/omdlib/main.py", line 232, in create_version_symlink
    os.symlink("../../versions/%s" % version, linkname)
OSError: [Errno 95] Operation not supported: '../../versions/2.0.0p12.cre' -> '/omd/sites/eizi_site1/version'

When using emptydir only, without NFS Checkmk is working.

Thanks for your answer

Check the permissions of the PV folder inside the container.
