Hi, This same error keeps happening to me: after writing some amount of data to an RBD image it gets stuck and no read or write operation on it works. Every operation hangs. I cannot resize, alter features, read or write data. I can mount it, but using parted or fdisk hangs indefinitely. In the end all I can do is remove the image. Again, I see no errors on the logs and Ceph's status is OK. I tried to alter some log levels, but still no helpful info. Is there anything I should check?
