Hi,
I was trying to set up a multi node dev environment. Till now, I was building
ceph by executing ./configure and make. I then used to test the features by
using vstart in a single node. Instead of it, if I still need to use the multi
node cluster for testing, what is the proper way to do?.
Hi,
I would use ceph-deploy
http://ceph.com/docs/master/start/quick-start-preflight/#ceph-deploy-setup but
... I've only done tests a few times and other people may have a more elaborate
answer to this question ;-)
Cheers

One thing being missed,
Samsung 850 Pro has only been available for about 1-2 months.
The OP, noted that drives are failing after approx 1 year. This would
probably mean the SSDs are actually Samsung 840 Pro. The
write-durabilities of 850 and 840 are quite different.
That being said, Sams

I don't think this is true.
If you have a SSD disk of 60Gb or 100GB then your TBW/day is really
limited (the disk is small then will wrote always on same sectors).
The bigger is the SSD the longer will be alive, you have limited write
per day then if your disk is bigger you have more sectors to
What about the Intel DC S3500 instead of the DC S3700?

A matter of x10 for TBW supported between the two. See the small
analysis I made previously in this thread regarding the cost per TBW.

I'd like to take a moment away from your regularly scheduled storage
revolution to talk about the Ada Initiative: who they are, what they do,
and why it is important to open source storage communities. I'm also going
to challenge you to raise $8192 for them, and I'll match that dollar for

Hey everyone, loving Ceph so far!
We are looking to role out a Ceph cluster with all SSD's. Our application is
around 30% writes and 70% reads random IO. The plan is to start with roughly 8
servers with 8 800GB Intel DC S3500's per server. I wanted to get some input on
the use of the DC S3500.

ceph nodes?

Hello Cephers,
I am a bit lost on the best ways of using ssd and hdds for ceph cluster which
uses rbd + kvm for guest vms.
At the moment I've got 2 osd servers which currently have 8 hdd osds (max 16
bays) each and 4 ssd disks. Currently, I am using 2 ssds for osd journals and
I've got 2x512
I think you should just skip 'ceph-deploy install' command and install your
version of the ceph package in all the nodes manually.
Otherwise there is ceph-deploy install --dev you can try out.
Thanks & Regards

That would not be possible with ceph-deploy *unless* you have a

Hi Somnath,
I will try out with ‹dev option which you told. Does it mean
that I have to remove osds and mon each time and then do ceph-deploy

The problem with the first option is that, I have to manually install in
5-6 nodes each time fo
Hey Alexandre,
Sounds like work has started on this (under the title "RBD Mirroring")
and is continuing in Hammer. I have updated the title and moved it to
Hammer so there will be a design discussion at CDS. Thanks!

We are also becoming interested in understanding and taming the impact
of deep scrubbing.
We may start running something similar to the cron tasks mentioned.
Looking at these fine examples of bash + awk I wondered if I could do
the job using the python rados api. I have attached my initial (un
