[ceph-users] Can I fix the devive name,when using image map?

Hi: I use image map to mount a ceph device to localhost,but I found that,the device name I can not control. This is a problem,when it's name changed,the FS on it or the database using this device may get wrongs. Can I control the device name? For exapme: [root@gate2 ~]# rbd showmapped id pool namespace image snap device 0 testpool test_img - /dev/rbd0 Can I map the device like this,just directly give the deveice name?like this: rbd map testpool/test_img /dev/rbd0 sz_cuitao(a)163.com
