Hello guys,
I am planning to do rbd images off-site backup with rbd export-diff and I was
wondering if ceph has checksumming functionality so that I can compare source
and destination files for consistency? If so, how do I retrieve the checksum
values from the ceph cluster?
That would be rather difficult. There is no checksum, but to have a
valid checksum you would need to verify the whole RBD image.
That means reading the whole image and calculating the checksum based on
that.
Thanks
Andrei
