Hi All,
All of this is using the latest version of RL and Ceph Reef
I've got an existing RBD Image (with data on it - not "critical" as I've
got a back up, but its rather large so I was hoping to avoid the restore
scenario).
The RBD Image used to be server out via an (Ceph) iSCSI Gateway, but we
are now looking to use plain old kernal module.
The RBD Image has been RBD Mapped to the client's /dev/rbd0 location.
So now I'm trying a straight `mount /dev/rbd0 /mount/old_image/` as a test
What I'm getting back is `mount: /mount/old_image/: unknown filesystem
type 'LVM2_member'.`
All my Google Foo is telling me that to solve this issue I need to
reformat the image with a new file system - which would mean "losing"
the data.
So my question is: How can I get to this data using rbd kernal modules
(the iSCSI Gateway is no longer available, so not an option), or am I
stuck with the restore option?
Or is there something I'm missing (which would not surprise me in the
least)? :-)
Thanks in advance (as always, you guys and gals are really, really helpful)
Cheers
Dulux-Oz
