Hi,
I am trying to map a rbd device in Ubuntu 14.04 (kernel 3.13.0-30-generic):
# rbd -p mypool create test1 --size 500
# rbd -p mypool ls
test1
# rbd -p mypool map test1
rbd: add failed: (5) Input/output error
and in the syslog:
Jul 4 09:31:48 testceph kernel: [70503.356842] libceph: mon2

Hi
I just follow the quickstart guide for creating a block image but always got
failed.
I am totally new to ceph. don't know where to find the problems.
Can you help? thanks.
The client output:

Hi,
Yesterday I finally updated our cluster to emperor (lastest stable
commit) and what's fairly apparent is a much higher RAM usage on the
OSD:

Has anyone noticed the same ? I mean 25% sudden increase in the idle
ram usage is hard to ignore ...
Those OSD are pre

Hi,
I wouldn't put those SSD's in raid, just use them separately as journals
for half of your's HDD's. This should make your write performance somewhat
better.

I use between 1 and 128 in different steps...
But 500mb write is the max playing around.
Uff its so hard to tune ceph... so many people have problems... ;-)

Hi,
I think, the problem is the rbd device. It's only ONE device.
I fully agree. Ceph excels in parallel performance. You should run
multiple fio instances in parallel on different RBD devices and even
better on different clients.
Then you wil

I just mentioned it in a different thread, make sure you do parallel
I/O! That's where Ceph really makes the difference. Run rados bench from

Just a FYI - I posted a setting very like this in another thread, and
remarked that it was "aggressive" - probably too much
Just thought to save some time )))

Hi David,
Do you mind sharing the howto/documentation with examples of configs, etc.?
I am tempted to give it a go and replace the Apache reverse proxy that I am
currently using.
cheers

Hi,
I extracted a disk with two partitions (journal and data) and copied its
content in the hope to restart the OSD and recover its content.

Thank you Luis for your response.
Quite unbelievable, but your solution worked!
Unfortunately, I'm stuck again when trying to upload parts of the file.

Hi,
I have a ceph cluster setup (with 45 sata disk journal on disks) and get
only 450mb/sec writes seq (maximum playing around with threads in rados
bench) with replica of 2
Which is about ~20Mb writes per disk (what y see in atop also)
Still not sure do I need the ceph's modified fastcgi or not.
But I guess this explains my problem with the installation:

It would be nice to have at least a workaround for this...

i am having issues running radosgw-agent to sync data between two
radosgw zones. As far as i can tell both zones are running correctly.
My issue is when i run the radosgw-agent command:
