[pve-devel] [PATCH v2 librados2-perl 2/7] mon_command: optionally ignore errors

[Aaron Lauterer]

In some situations we do not want to abort if the Ceph API returns an
error. For example if we run the 'osd ok-to-stop' or similar calls, we
are interested in the status message in the error case.

I split the adding of "noerr" into a separate patch for a clearly
separated history
