Description

- borrow large non-zeroed image, ten gig in my case
- upload it via cli, format 2 is set
- try to download the image, it will got corrupted (cksum mismatch) or rbd export process will print a lot of failed seeks:

Exporting image: 16% complete...rbd: error seeking destination image to offset 2302672896
rbd: error seeking destination image to offset 2411724800
rbd: error seeking destination image to offset 2415919104
rbd: error seeking destination image to offset 2420113408
rbd: error seeking destination image to offset 2424307712
rbd: error seeking destination image to offset 2428502016
rbd: error seeking destination image to offset 2319450112
rbd: error seeking destination image to offset 2432696320

underlying fs is just a regular ext4, Ceph version is f7ec448d6579f965eec184416a97b47ae27ab47a

There is no errors when output seeking/buffering is suppressed, likely when exporting to stdout.

This is a duplicate of #9936 and will be backported to Giant soon. In the meantime, as a workaround you can export to the console and redirect the console to a file.
