Hi every one,
I finally and happily managed to get my Ceph cluster (3 monitors among 8
nodes, each with 9 OSDs) running on version 0.71, but the "rbd map"
command shows a weird behaviour.
I can list pools, create images and snapshots, alleluia!
However, mapping to a device with "rbd map" is not working. When I try
this from one of my nodes, the kernel says:
libceph: bad option at 'rw'
Which "rbd" translates into:
add failed: (22) Invalid argument
Any idea of what that could indicate?
I am using a basic config: no authentication, default crushmap (I just
changed some weights), and basic network config (public net, cluster
net). I have tried both image formats, different sizes and pools.
Moreover, I have a client running rbd from Ceph version 0.61.9, and from
there everything works fine with "rbd map" on the same image. Both nodes
(Ceph 0.61.9 and 0.71) are running Linux kernel 3.2 for Debian.
Hope you can provide some hints. Best regards,
