Hi, all: My ceph version is ceph version 0.39 (commit:321ecdaba2ceeddb0789d8f4b7180a8ea5785d83) When I try to map a long name rbd image to device, it would hang for long time. For example: sudo rbd map iqn.2012-01.com.sample:storage.ttttttt --secret /etc/ceph/secretfile sudo rbd map iqn.2012-01.com.sample:storage.abcdef --secret /etc/ceph/secretfile It would not hang at every long name image, however, it only happens when the image name is very long. Is it a known issue?
