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.

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

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?

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?

?. If I need to run
benchmarks(using rados bench or other benchmarking tools) after any code
change, what is the right practice to test some change in a multi node dev
setup? ( Multi node setup is needed as part of getting right performance
results in benchmark tests)

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

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

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
you have for your client.volumes?

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.

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
