Hi,
have you tried to create a snapshot of that image and export the
snapshot? Or maybe clone the snapshot first and then export it? Does
it also fail?
Zitat von Rhian Resnick <rresnick@xxxxxxx>:
Evening,
We are running into issues exporting a disk image from ceph rbd.
When we attempt to export an rbd image in a cache tiered
erasure-coded pool on Luminus.
All the other disks are working fine but this one is acting up. We
have a bit of important data on other disks so obviously want to
make sure this doesn't happen to those.
[root@ceph-p-mon1 home]# rbd export one/one-177-588-0 one-177-588-0
Exporting image: 8% complete...rbd: error reading from source image

Any thoughts would be appreciated.
