Check tty session for remote execution. Could explain why it worked when
you were logged in. Possibly ansible is running mount command without
tty. Check your settings for that user and see if they required to have
tty to make remote calls such as mount.

I don't known how rbd read-ahead is working,
but with qemu virtio-scsi, you can have read merge request (for sequential
reads), so it's doing bigger ops to ceph cluster and improve throughput.
virtio-blk merge request will be supported in coming qemu 2.3.

Linux caching (write caching, writeback) is working fine with newer virt-io

Hi to the ceph-users list !
We're setting up a new Ceph infrastructure :
- 1 MDS admin node
- 4 OSD storage nodes (60 OSDs)
each of them running a monitor
- 1 client
Each 32GB RAM/16 cores OSD node supports 15 x 4TB SAS OSDs (XFS) and 1
SSD with 5GB journal partitions, all in JBOD
Hi again everyone after some tests I have noticed that the data deleted on the

In the filesystem the uses space is 256MB and in ceph status shows us 25459MB
thats 24GB so I was wondering if there is any way to reclaim space from deleted
files or

Hi Greg,
Thanks for your input and completely agree that we cannot expect developers
to fully document what impact each setting has on a cluster, particularly in
a performance related way
That said, if you or others could spare some time for a few pointers it
would be much appreciated and I will

Thank you for your reply.
We are also thinking about using the S3 API but we are concerned about how
compatible it is with the real S3. For instance, we would like to design the
system using pre-signed URL for storing some objects. I read the ceph
documentation, it does not mention

I will attend whole event, so if you would like to talk about Ceph - please

There was strong Ceph (from Inktank and the community) representation last

Yeah, it would be nice to talk about Ceph, but meeting up at your booth sounds
like a good idea. We’re just plain visitors.

Hi Josef,
I'm going to benchmark a 3nodes cluster with 6ssd each node (2x10 cores 3,1ghz).
From my previous bench, you need fast cpus if you need a lot of iops, and
writes are lot more expansive than reads.
Now i'm you are doing only small iops (big blocks / big throughput), you don't
need too
I think I might have found the issue

There's no easy process. If you know that a lot of the removed data is on
buckets that shouldn't exist anymore then you could start by trying to
