When I do gatherkeys, ceph-deploy tells me:

Given that I downloaded ceph-deploy from the ceph.com debian repository, I'm
hoping that Debian is supported and that I have something screwy somewhere.
Any suggestions?
Thanks

Hello every one,
Just ran a fresh install of version Emperor on an empty cluster, and I
am left clueless, trying to troubleshoot cephx. After ceph-deploy
created the keys, I used ceph-authtool to generate the client.admin
keyring and the monitor keyring, as indicated in the doc. The

Hi,

You have to explicitly set public ACL on each object.
Ok, but this also does not work with radosgw + s3cmd:
s3cmd setacl -P s3://test/fstab

Hello all.
I have a Ceph cluster using XFS on the OSDs. Btrfs is not available to
me at the moment (cluster is running CentOS 6.4 with stock kernel).
I intend to maintain a full replica of an active ZFS dataset on the
Ceph infrastructure by installing an OpenSolaris KVM guest using
rbd-fuse to ex
The trouble with using ZFS copies on top of RBD is that both copies of
any particular block might end up on the same OSD. If you have
disabled replication in Ceph, then this would mean a single OSD
failure could cause data loss. For that reason, it seems it would be
better to do the replication i
Hi every one,
I am currently testing a use-case with large rbd images (several TB),
each containing an XFS filesystem, which I mount on local clients. I
have been testing the throughput writing on a single file in the XFS
mount, using "dd oflag=direct", for various block sizes.

Did you try moving the journals to separate SSDs?
It was recently discovered that due to a kernel bug/design, the journal
writes are translated into device cache flush commands, so thinking
about that I wonder also whether there would be performance improvement
in the case that journal and OSD
Looking at this review, it seems the SSD and spinning disk are in a
flat LBA address space:

Hi James,
Unfortunately, SSDs are out of budget. Currently there are 2 SAS disks
in RAID0 on each node, split into 9 partitions: one for each OSD journal
on the node. I benchmarked the RAID0 volumes at around 500MB/s in
sequential sustained write, so that's not bad — maybe access latency is

An update on this issue:
Explicitly setting the "keyring" parameter to its default value, in the
client section, like this:
[client.admin]
keyring = /etc/ceph/ceph.client.admin.keyring
solves the problem in the particular case when ONLY
"auth_cluster_required" is set to "cephx", and the two
I will try to look into this issue of device cache flush. Do you have
a tracker link for the bug?
How I wish this were a forum! But here is a link:

And this:

Thanks for the input John.
So I should leave ZFS checksumming on, disable ZFS replicas and rely
on Ceph RBD replicas.
Is it even sane to use rbd-fuse for this?
On a related note, is there any discard/trim support in rbd-fuse? Else
I won't ever be able to thin-out the RBD image once it is allocate
On a related note, is there any discard/trim support in rbd-fuse?
Apparently so (but not in the kernel module unfortunately).

Hi,
thanks for the hint. I tried this again and noticed that the time out message
does seem to be unrelated. Here is the log file for a stalling request with
debug turned on:

RedHat just added RBD support in qemu-kvm-rhev in RHEV 6.5. I don't
know if that will trickle down to CentOS but you can probably
recompile it yourself like we did.

Good day!
We ve noticed such things recently during some osd recovery things like
scrubbing or so. Restarting OSD did the trick. We had even 404 errors until
deep scrubbing ended.
Any noise in ceph -w?

Ok, librbd (which is used by the qemu alternative) supports discard,
not the rbd kernel module does not. Neither of these are available to

Aside from the messages about ceph-deploy saying debian is not supported on two
