I am planning to use ceph object gateway to store data in ceph
cluster.I need two different users of Rados gateway to store data in
different pools.How can I create and assign different pools to
different ceph object gateway users?
Thanks in advance

Hi list,
Can RADOS fulfil the following use case:
I wish to have a radosgw-S3 object store that is "LIVE",
this represents "current" objects of users.
Separated by an air-gap is another radosgw-S3 object store that is "ARCHIVE".
The objects will only be created and manipulated by radosgw.

Hi Dan,
Maybe I misunderstand what you are trying to do, but I think you are trying to
add your Ceph RBD pool into libvirt as a storage pool?
If so, it's relatively straightforward - here's an example from my setup:

Tuan,
I had a similar behaviour when I've connected the cache pool tier. I resolved
the issues by restarting all my osds. If your case is the same, try it and see
if it works. If not, I guess the guys here and on the ceph irc might be able to
help you.
Cheers

Thanks Dan (Doctor, doctor...)
Correct. I'd like to abstract the details of the rbd storage from the VM
definitions as much as possible (like not having the monitor IPs/ports
defined). I plan on experimenting with monitors and so forth on ceph and would
like to not have to touch every single VM
Hi,
does anyone know if journals are involved when ceph rebalance data (on
osd crash for example) or when replication size is changed?

What I've found is the nicest way of handling this is to add all the
mons to your ceph.conf file. The QEMU client will use these if you
don't define any in the libvirt config.
Similarly, define a libvirt 'secret' and you can use that for auth, so
you only have one place to change it. My enti
Bonjour Emmanuel,
The journals are used for all write operations on an OSD. They will be used if
an OSD crashes and others need to create new copies of objects.

The best way to setup SSH is to use a ~/.ssh/config file It solves
a lot of issues!
Example:
~/.ssh/config
Host ceph1 cephosd1
HostName 192.168.1.10
User ceph
Host ceph2 cephosd2
HostName 192.168.1.11
User ceph
With that you can just do a "ssh ceph1" for example... All other S

I recommend using ceph-deploy. mkcephfs is deprecated and should not be
used anymore.

Hello Mark -
Can you please paste your keystone.conf? Also It seems that Icehouse install
that I have does not have keystone.conf. Do we need to create one? Like I said,
adding WSGIChunkedRequest On in Keystone.conf did not solve my issue.

Hi list,
During my test, I found ceph doesn't scale as I expected on a 30 osds
cluster.
The following is the information of my setup:
HW configuration:
15 Dell R720 servers, and each server has:
Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz, 20 cores and hyper-thread
enabled.
128GB memo
If you're running a single client to drive these tests, that's your
bottleneck. Try running multiple clients and aggregating their numbers.

While I certainly can (attached) - if your install has keystone running
