Description Guillaume Abrioux 2019-08-07 13:46:45 UTC 
Description of problem:

Cloned from https://tracker.ceph.com/issues/38548

When requesting ceph-volume to print json output, messages and errors are printed to stdout.
The printed json can't be consumed given that it's seen as invalid json.

seen on ceph version 14.2.2-298-g0bdfdc6 (0bdfdc6b5433736bd11c321ecfa559f3b30f9187) nautilus (stable)

How reproducible:
100%

Steps to Reproduce:
1. ask ceph-volume to output using --format json


Actual results:
ceph-volume outputs json with extra messages in addition on stdout, which makes the json as invalid.

Expected results:
ceph-volume outputs only json data on stdout.


Typical output:

[root@osd1 /]# ceph-volume simple scan /dev/sda1 --stdout 2>/dev/null
Running command: /usr/sbin/cryptsetup status /dev/sda1
Running command: /bin/mount -v /dev/sda1 /tmp/tmp_NrdoM
stdout: mount: /dev/sda1 mounted on /tmp/tmp_NrdoM.
Running command: /bin/umount -v /tmp/tmp_NrdoM
