Hello all,
I have a question about how to calculate file size when mount a block
device from rbd image .
[Cluster information:]
1.The cluster with 1 mon and 6 osds. Every osd is 1T. Total spaces is 5556G.
2.rbd pool:replicated size 2 min_size 1. num = 128. Except rbd pool other
pools is empty.

2.Use dd command to create a 1.2T file.
#dd if=/dev/zero of=/mnt/ceph-mount/test12T bs=1M count=12288000
I think you're off by one zero
12288000/1024/1024
11
Means you're instructing it to create a 11TB file on a 1.5T
