Hi All,
I have a cluster of size 3120 GB running, but i noticed that at my monitor
node the log is consuming lot of space and it is increasing very rapidly.
In one day itself it goes to 100 GB.
Please help me to stop or reduce the the logging at monitor.

Any news on this ?
I have the same issue, but the cache only masks the problem. If you
restart radosgw, you'll get it again (once for each bucket).

thanks for the very usefull hint! With "ceph osd set noout" it's works

Hello everyone,
I find the plugin for wireshark to decode ceph message in src code, but I
wonder how to use it, and is there any plugin for tcpdump?

Greetings,
I am trying to use CEPH cluster, with erasor encoding, preferrably with
CEPHFS as a disk storage unit for Symantec NetBackup.
Problem currently is that Symantec Netbackup Servers packages do not come
for ubuntu at all and for CEPHFS, I will need Ubuntu 12.04 (3.8 linux
kernal).

Hi,
I have another idea for you:
In NetBackup (with proper licensing) you can configure something called
Cloud Storage Servers. Essentially a storage unit in Rackspace Cloudfiles
or Amazon S3. There's an option to change url to the storage server, so you
can replace it with the url to your RadosGW
Hello,
I am wondering if there is any detailed documentation for obtaining I/O
statistics for a Ceph cluster.
The important metrics I'm looking for are: the number of operations, size of
operations, and latency of operations - by operations I'm referring to
read/write.
I've seen what look like

Hi,

We have done this crush map to make thing work.
srv1 and srv1ssd are the same physical server (same srv2,3,4)
we split it in the crush to make two parallel hierarchies.
This example is working,
I actually need to see what happens before it starts looping. What

All,
I have a situation on my RHEL 6.4 cluster that seems to be caused by
ceph-deploy changing the file permissions on /etc/ceph/ceph.conf after running
a command such as "ceph-deploy mon create node2 node3". The idea was to create
additional monitors for a healthy 3 node cluster that already

I want to double the number of pgs available for a pool, however I
want to reduce as much as possible the resulting I/O storm (I have
