Hello guys,
Was wondering if anyone has tried using the Crucial MX100 ssds either for osd
journals or cache pool? It seems like a good cost effective alternative to the
more expensive drives and read/write performance is very good as well.
Thanks

Performance seems quite low on those. I’d really step it up to intel s3700s.
Check the performance benchmarks here and compare between them:

i have meet the same issue , when i want to use prepare .
when i use --zap-disk , it is ok. but if use prepare to define journal
device, failed
ceph-disk-prepare --zap-disk --fs-type btrfs --cluster ceph -- /dev/sdb

i am looking for the method how to ramdisk with Ceph , just for test
environment, i do not have enough SSD for each osd. but do not how to
move osd journal to a tmpfs or ramdisk.
hope some one can give some guide.

Ilya doesn't need to upgrade anything ;)
Larry, if
Ilya how are you? Thats cool tell me if changing the tunable and disabling the

why i went for the kern upgrade

I'm having the exact same problem. I'll try solving it without upgrading
the kernel.

Hi All,
There is a new release of ceph-deploy, the easy deployment tool
for Ceph.
This release comes with a few improvements towards better usage of ceph-disk
on remote nodes, with more verbosity so things are a bit more clear when they
execute.
The full list of fixes for this release can be fou
IIlya,
Sorry for my delayed reply. It happens on a new cluster I just created. I'm
just testing right out of the default rbd pool.

Hello Ceph Experts :) ,
I am using ceph ( ceph version 0.56.6) on Suse linux.
I created a simple cluster with one monitor server and two OSDs .
The conf file is attached
When start my cluster - and do "ceph -s" - I see following message

Hi,
when I am running
rados bench -p benchmark 300 write --run-name bench --no-cleanup
I got weird stalling during writes, sometimes I got same write speed
for few minutes and after some time it starts stalling with 0 MB/s for
minutes
My configuration:

I have 3 nodes each running a MON and 30 OSDs. When I test my cluster with
either rados bench or with fio via a 10GbE client using RBD I get great initial
speeds >900MBps and I max out my 10GbE links for a while. Then, something goes
wrong the performance falters and the cluster stops responding
cruhmap file is attached. I'm running kernel 3.13.0-29-generic after another
person suggested. But the kernel upgrade didn't fix anything for me. Thanks!

Now that OSCON is in our rearview mirror we have started looking to

So there are two problems. First, you either have erasure pools or had
them in the past
Hi Ilya, thank you so much! I didn't know my crush map was all messed up.
Now all is working! I guess it would have worked even without upgrading the
kernel from 3.2 to 3.13.

Hello,
I've run out of ideas and assume I've overlooked something very basic. I've
created 2 ceph clusters in the last 2 weeks with different OSD HW and private
network fabrics - 1GE and 10GE. I have never been able to get the OSDs to come
up to the 'active+clean' state. I have followed your on
So I've been having a seemingly similar problem and while trying to follow
the steps in this thread, things have gone very south for me.
Kernal on OSDs and MONs: 2.6.32-431.20.3.0.1.el6.centos.plus.x86_64 #1 SMP

Kernal on RBD host: 3.2.0
Why do you have a MDS active? I'd suggest getting rid of that at least
until you have everything else working.
I see you've set nodown on the OSDs, did you have problems with the OSDs
flapping? Do the OSDs have broken connectivity between themselves? Do
you have some kind of firewall interf
One additional note, I've got a fair amount of data on the rbd volume,
which I need to recover in one way or another.

MDS: I assumed that I'd need to bring up a ceph-mds for my cluster at initial
bringup. We also intended to modify the CRUSH map such that it's pool is
resident to SSD(s). It is one of the areas of the online docs there doesn't
seem to be a lot of info on and I haven't spent a lot of time researc
What happens if you remove nodown? I'd be interested to see what OSDs
it thinks are down. My next thought would be tcpdump on the private
interface. See if the OSDs are actually managing to connect to each other.
For comparison, when I bring up a cluster of 3 OSDs it goes to HEALTH_OK

Given the HW you list below, that might be a tall order, particular CPU

What is your OS running off, HDDs or SSDs?
