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: 2012-06-26 18:39:42.283752 7f141e43f700 0 -- 172.18.0.14:0/1002349 >> 172.18.0.14:6806/11061 pipe(0x7f141eaa59a0 sd=3 pgs=0 cs=0 l=0).connect claims to be 172.18.0.14:6806/2331 not 172.18.0.14:6806/11061 - wrong node! 2012-06-26 18:39:42.284243 7f141e43f700 0 -- 172.18.0.14:0/1002349 >> 172.18.0.14:6806/11061 pipe(0x7f141eaa59a0 sd=3 pgs=0 cs=0 l=0).connect claims to be 172.18.0.14:6806/2331 not 172.18.0.14:6806/11061 - wrong node! 2012-06-26 18:39:42.484832 7f141e43f700 0 -- 172.18.0.14:0/1002349 >> 172.18.0.14:6806/11061 pipe(0x7f141eaa59a0 sd=3 pgs=0 cs=0 l=0).connect claims to be 172.18.0.14:6806/2331 not 172.18.0.14:6806/11061 - wrong node! 2012-06-26 18:39:42.885548 7f141e43f700 0 -- 172.18.0.14:0/1002349 >> 172.18.0.14:6806/11061 pipe(0x7f141eaa59a0 sd=3 pgs=0 cs=0 l=0).connect claims to be 172.18.0.14:6806/2331 not 172.18.0.14:6806/11061 - wrong node! 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?
