Hi all,
I have ever to setup the cache-pool for my pool.
But had some proplems about cache-pool running, so I removed the cache
pool from My CEPH Cluster.
The DATA pool currently don't use cache pool, but "lfor" setting still

*lfor* seems is a setting, not flag.

Hi, first off: long time reader, first time poster :)..
I have a 4 node ceph cluster (~12TB in total) and an openstack cloud

Everything we have is Suse based and ceph 0.80.8
Now, the cluster works fine.. :

Hi eric, thanks for the reply.
As far as I can tell client.glance already already has all the rights
needed to the images pool?

Hi,
Can you check if you can import the images directly to the pool?
# rbd -p images --id glance --keyring
/etc/ceph/ceph.client.glance.keyring import
If that command goes well, you may have to go over with glance config file.

Hey,
We keep hearing that running Hypervisors (KVM) on the OSD nodes is a bad
idea. But why exactly is that the case?
In our usecase, under normal operations our VMs use relatively low amounts
of CPU resources. So are the OSD services, so why not combine them? (We use

We just had a fairly extensive discussion about this on the thread "running
Qemu / Hypervisor AND Ceph on the same nodes". Check that out in the

Like the last comment on the bug says, the message about block migration (drive
mirroring) indicates that nova is telling libvirt to copy the virtual disks,
which is not what should happen for ceph or other shared storage.
For ceph just plain live migration should be used, not block migration.
Yes, it's expected. The crush map contains the inputs to the CRUSH hashing
algorithm. Every change made to the crush map causes the hashing algorithm
to behave slightly differently. It is consistent though. If you removed
the new bucket, it would go back to the way it was before you made the

In that case, I'd set the crush weight to the disk's size in TiB, and mark
the osd out:
ceph osd crush reweight osd.

Thanks for the insights, Greg. It would be great if the CRUSH rule for an EC
pool can be dynamically changed…but if that’s not the case, the troubleshooting
doc also offers up the idea of adding more OSDs, and we have another 8 OSDs
(one from each node) we can move into the default root.

Hi,
lrwxrwxrwx 1 root root 10 Apr 4 16:27 1618223e-b8c9-4c4a-b5d2-ebff6d64cb12 ->

looks encouraging. Could you
sudo sgdisk --info 1 /dev/sdb
to check that it matches ? If you're on IRC feel free to ping me (CEST
France/Paris time) and we can have a debug session.

I see that ceph has 'ceph osd perf' that gets the latency of the OSDs.
Is there a similar command that would provide some performance data
about RBDs in use? I'm concerned about out ability to determine which
RBD(s) may be "abusing" our storage at any given time.

It doesn't seem so interesting to switch from deadline to cfq with HDD.

Hi,
I tried to install firefly v0.80.9 on a freshly installed RHEL 6.5 by following
http://ceph.com/docs/master/start/quick-ceph-deploy/#create-a-cluster but it

misreading the instructions somehow ?

I'm not sure exactly what your steps where, but I reinstalled a monitor
yesterday on Centos 6.5 using ceph-deploy with the /etc/yum.repos.d/ceph.repo
from ceph.com which I've included below.
