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 host.( I tried creating 10 volumes, but all are
created in same host 'slave1') I I haven't changed crushmap and I am using
the default one which came along with ceph-deploy.
nova-manage version
2013.2
host master {
id -2 # do not change unnecessarily
# weight 0.010
alg straw
hash 0 # rjenkins1
item osd.0 weight 0.010
}
host slave1 {
id -3 # do not change unnecessarily
# weight 0.010
alg straw
hash 0 # rjenkins1
item osd.1 weight 0.010
}
host slave2 {
id -4 # do not change unnecessarily
# weight 0.010
alg straw
hash 0 # rjenkins1
item osd.2 weight 0.010
}
root default {
id -1 # do not change unnecessarily
# weight 0.030
alg straw # do not change bucket size (3) unnecessarily
hash 0 # rjenkins1
item master weight 0.010 pos 0
item slave1 weight 0.010 pos 1

Second Issue
I am not able to attach volumes to instances if hosts differ. Eg: If
volumes are created in host 'slave1' , instance1 is created in host
'master' and instance2 is created in host 'slave1', I am able to attach
volumes to instance2 but not to instance1.
Did someone face this issue in openstack with ceph ?.
