My ceph cluster suddenly warned about disk full. I investigated the usage of the rbd volume and found that there are two images with the same name:
There are two entries "vm-110-disk-1" which pumped up the total size to 11TB.
when I do "rbd info vm-110-disk-1" it only shows one entry.
Is there any method to check whether it is true that the same image occupied double space in the rbd? Or is there any way to solve this issue?
Code:
