Unable to unmap rbd device (Jewel)

[Diego Castro <diego.castro@xxxxxxxxxxxxxx>]

Here's one of my nodes that can't unmap a device:

[root@nodebr6 ~]# rbd unmap /dev/rbd0

2016-04-27 11:36:56.975668 7fcd61ae67c0 -1 did not load config file, using default settings.

Option -q no longer supported.

rbd: run_cmd(udevadm): exited with status 1

rbd: sysfs write failed

rbd: unmap failed: (16) Device or resource busy

[root@nodebr6 ~]# fuser -amv /dev/rbd0

                     USER        PID ACCESS COMMAND

/dev/rbd0:

[root@nodebr6 ~]# ll /sys/block/rbd0/holders/

total 0

This is a Centos 7.2 (3.10.0-327.4.5.el7.x86_64)
