Remove unrelated log output from command line utils?

Remove unrelated log output from command line utils?

[Nick Bartos]

Sometimes, I get (what seems like) unrelated log output when running a
command.  For example:

Command ran: rbd -m 172.18.0.13:6789,172.18.0.15:6789,172.18.0.14:6789 list

Return code is 0, as expected.

Stdout is this as expected:
libvirt_172.18.0.13
libvirt_172.18.0.14
libvirt_172.18.0.15
libvirt_save_node-172-18-0-14
mysql
node-172-18-0-13novadisk0
node-172-18-0-14novadisk0
node-172-18-0-15novadisk0
swift_node-172-18-0-13
swift_node-172-18-0-14
swift_node-172-18-0-15

However, this is on stderr, which is not expected:

I think the stderr output should only be going to the logs, not to an
arbitrary command line utility.

Is there any way to change this behaviour?  The ceph version is
0.47.2, and here is the ceph.conf:


# cat /etc/ceph/ceph.conf
[global]
;   auth supported = cephx

    log file = ""
    log to syslog = true
    clog to monitors = false
    clog to syslog = true

    # Tone down insane number of osd::tracker messages
    debug optracker = 1

Yes, set 'log to stderr = false' in your ceph.conf, or add
--no-log-to-stderr to your commands. You can do the same for errors
with 'err to stderr = false' and --no-err-to-stderr.
