take a look at the link ,

could you explain point 2, 3 in that picture.

is in momory or on disk already?

my question is from my test.
let's take a example. object1(4MB)--> pg 0.1 --> osd 1,2,3,p1
when client is writing object1, during the write , osd1 is down. let suppose
2MB is writed.

when the connection to osd1 is down, what does client do? ask monitor for
new osdmap? or only
Hi fellow cephers,
I'm being asked questions around our backup of ceph, mainly due to data
deletion.
We are currently using ceph to store RBD, S3 and eventually cephFS; and we
would like to be able to devise a plan to backup the information as to
avoid issues with data being deleted from the clus
Any thoughts on how to improve the delete process performance?
thanks,

Luis,
you may want to take a look at rbd export/import and export-diff import-diff
functionality. this could be used to copy data to another cluster or offsite.
S3 has regions, which you could use for async replication.
Not sure how the cephfs work for backups.

Hi Nathan,
that was indeed the Problem! I was increasing the max_pid value to 65535
and the problem is gone! Thank you!
It was a bit misleading that there is also a
/proc/sys/kernel/threads-max, which has a much higher number. And since
I was only seeing around 400 processes and wasn't aware that

I have observed this crash on ubuntu with kernel 3.13 and centos with 3.16 as
well now.
rbd hangs, and iostat shows something similar to the Output below.

I'm currently running 2 ceph clusters (ver. 0.80.1) which are providing
secondary storage for CloudPlatform. Each cluster resides in a different
datacenter and our federated gateway consists of a region (us-east-1) with 2
zones (zone-a [master], zone-b [slave]). Objects appear to be

Thanks for your response.

I don't know how radosgw objects are stored, but have you considered a

I've had some issues in my secondary cluster. I'd like to restart
replication from the beginning, without destroying the data in the
secondary cluster.
Reading the radosgw-agent and Admin REST API code, I believe I just need to
stop replication, delete the secondary zone's log_pool, recreate the
Is osd.12 doing anything strange? Is it consuming lots of CPU or IO? Is
it flapping? Writing any interesting logs? Have you tried restarting it?
If that doesn't help, try the other involved osds: 56, 27, 6, 25, 23. I
doubt that it will help, but it won't hurt.
