Hi,
I have a three node ceph cluster. ceph -w says health ok . I have
openstack in the same cluster and trying to map cinder and glance onto rbd.
I have followed steps as given in
http://ceph.com/docs/next/rbd/rbd-openstack/

I was trying openstack on ceph. I could create volumes but I am not able to
attach the volume to any running instance. If I attach a instance to an
instance and reboot it, it goes to error state.
Compute error logs are given below.

Hi all,
I need to know whether someone else also faced the same issue.
I tried openstack + ceph integration. I have seen that I could create
volumes from horizon and it is created in rados.
When I check the created volumes in admin panel, all volumes are shown to
be created in the same h

I am surprised that no
one else has seen or reported this issue. Any idea?

Hi,
I have an openstack cluster which runs on ceph . I tried running
hadoop inside VM's and I noticed that map tasks take long time to complete
with time and finally it fails. RDB read/writes are getting slower with
time. Is it because of too many objects in ceph per volume?
I have 8 node clu
This can help you.

Hi Daniel,
Can you provide your exact crush map and exact crushtool command
that results in segfaults?

results in benchmark tests)

How do I use ceph-deploy in this case?. How do I get ceph-deploy to use my
privately built ceph package (with my changes) and install them in all
ceph nodes?

Even when I try ceph-deploy install --dev , I
am seeing that it is getting installed from official ceph repo. How can I
install ceph from my github repo or my local repo in all ceph nodes? (Or
any other possibility? ). Someone can help me in setting this?

What happens for a situation with [1,0.5,1] ? Is osd.0
always returned?
D) After calculating primary based on the affinity values, I see a shift of
osds so that primary comes to the front. Why is this needed?. I thought,
primary affinity value affects only reads and hence, osd ordering need not
rack1 and may become
unbalanced.(Ensure enough storage in rack1)
Thanks,
Johnu

complex. As in your eg: if osd0, osd1,osd2 has primary affinity value
of [1,0.5,0.1] and there are 600 pgs, the final distribution comes in
440:140:20 or 22:7:1 which is slighly skewed from expected.
