Hi,
Can someone please let me know whether there is any documentation for
installing Havana release of Openstack along with Ceph.
Thanks,

Hi list,
I've noticed that a patch was submitted in October last year to enable
POSIX ACLs in cephfs, but things have gone very quiet on that front
recently.
We're looking to use cephfs in our organisation for resilient storage of
documents, but without ACLs we would have some issues. Are th
that code is already in test branch of ceph-client, I think it will go
into 3.14 kernel.

Hi,
I am trying to use hadoop distcp while copying data from hdfs to s3. Hadoop
distcp devides the data in to multiple chunks and sends the data parellely
so that faster performance is achieved. However this is failing against
ceph s3 indicating a mismatch between md5 and etag returned by s3. Howe
Hi,
Many thanks for this.
Cheers
Alex

Hi,
I noticed in the documentation that the OSD should use 3 ports per OSD
daemon running and so when I setup the cluster, I originally opened
enough port to accomodate this (with a small margin so that restart
could proceed even is ports aren't released immediately).
However today I just noticed
Hi Guys,
Thanks for reply Sage.
Yes librados seems to be right direction for our long term development.
For short term, I guess we will stick on CephFS for files, Sorl for
metadata and Riak for thumbnails.

Hi all,
Is there somewhere a list of parameters that can('t) be changed using
the parameter injection (ceph tell ..injectargs)?
Thanks!!
Kind regards

Hello,
I do not know if it will have all the options, but you can use
$ ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok config show
This will give the settings for osd.0 .

Almost! The primary OSD sends out the data to its replicas simultaneously
with putting it into the journal.

Hi,
I need a little bit help.
We have an 4-node ceph cluster and the clients run in trouble if one
node is down (due to maintenance).
After the node is switched on again ceph health shows (for a little time):
HEALTH_WARN 4 pgs incomplete; 14 pgs peering; 370 pgs stale; 12 pgs
stuck unclean; 36 req

Udo,
I think you might have better luck using "ceph osd set noout" before doing
maintenance, rather than "ceph osd set nodown", since you want the node to
be marked down to avoid having I/O directed at it (but not out to avoid
having recovery backfill begin.)

Hi,
I have a cluster that contains 16 OSDs spread over 4 physical
machines. Each machines runs 4 OSD process.
Among those, one isue periodically using 100% of the CPU. if you
aggregate the total CPU time of the process over long periods, you can
clearly see it uses roughtly 6x more CPU than any o

Hi,
I have a cluster of two kvm hosts and three ceph servers (osd+mons).
I've been doing some basic performance tests, and I discover that I
ftp server running in the guest is slow compared to a ftp server in
the host. The same with a Samba file server.
For example, ncftpget agaisnt the guest rep

Hi Sage,
I have a similar question, I need 2 replicas (one on each rack) and I would

Has anyone looked at or better - actually tried - Mellanox's libvma to
accelerate Ceph's inter-OSD, client-OSD, or both? Looks like potential for
drop-in latency improvements, or am I missing something...
