Thank you for the reply.  I don't have access to the exact same
configuration at the moment, so I tried mimicking the setup with virtual
machines, and everything worked correctly.  Perhaps I just did something
dumb on the real boxes.

It might be next week before I get another chance to play with it,
but I will try to rebuild it just like I did before at work, and
see if I run into the same problem, or if it really was just me.

Cheers,
Chris

No, it's most certainly not expected.  If you are willing to help debug this,
let's start with the output of 'rbd info'.  Return to the failing setup, do
'rbd map ', make sure it fails, and, on the same box, do 'rbd info
'.

[ceph-users] rbd: add failed: (34) Numerical result out of range

2014-06-09 Thread lists+ceph 

I was building a small test cluster and noticed a difference with trying
to rbd map depending on whether the cluster was built using fedora or
CentOS.

When I used CentOS osds, and tried to rbd map from arch linux or fedora,
I would get "rbd: add failed: (34) Numerical result out of range".  It
seemed to happen when the tool was writing to /sys/bus/rbd/add_single_major.

If I rebuild the osds using fedora (20 in this case), everything
works fine.

In each scenario, I used ceph-0.80.1 on all the boxes.

Is that expected?

Yes llya. From that command output only, I assumed this must be
rados_classes issue. After that copied in exact location and restarted all
the nodes.

Great, I was just going to have you restart the osds.  Do you know why
there wasn't a rados_classes on one (?) of the osds?  (I assume the
'find' result that you pasted came from the monitor and it is one or
more osds that lacked rados_clases?)

Hi All,

Thanks a lot to one and all.. Thank you so much for your support. I found
the issue with your clues.

*Issue is : root filesystem does not have /usr/lib64/rados_classes*

After adding rados_classes and restarting all the nodes, I could able map
the block devices.

Thanks,
Srinivas.

OK, so the kernel is not to blame here.  This is probably a class path
issue.

- Can you try to locate a libcls_rbd.so library on your
system?

- What's the value of osd_class_dir conf variable?

My deployment is on our private distribution of Linux kernel 3.10.33 and
ceph version is 0.72.2

I could able to create image with command " rbd create sample --size 200".


What is the RBD format of the image?

$ rbd info sample

I don't think it's the problem, but it could be that the krbd doesn't 
support format 2 yet.
