Subject: mgr/cephadm: show unhandled exceptions during `host add`
X-Git-Tag: v17.1.0~924^2~2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=dac9225085a1f6d2eeaf209fc3d77c54208db2e8;p=ceph.git

mgr/cephadm: show unhandled exceptions during `host add`

138700e59bcd assumes stderr will always have a line containing the
prefix 'ERROR', which leads to an empty error reason when `check-host`
fails with an unhandled exception
