Hi @all,
I got some errors after compiling an configuring ceph on Scientific
Linux 6. ( This works all fine with no errors)
First of all I want to explain my Systems:
Server0-3:
- Scientific Linux 6:
- Self compiled Kernel 2.6.38.4 from Kernel.org with ceph-modules
- 4 partitions:
- / <--- 20 GB - ext4
- /srv/cloud <--- 20 GB - ext4
- /dev/sda5 <--- 1 GB - ext4 ceph journaling system
- /dev sda6 <--- 50 GB - ext4 ceph fs mounted to /mnt/data
I didn't use brtfs, because ext4 is an requirement of my professor (I'm
writing my bachelor thesis)
My ceph.conf: http://pastebin.com/vdwfHNy3
- 3 OSD
- 2 MDS
- 3 Monitors
---------------------------
Now to my errors I got.
First I alwas get on ceph -w following "error":
"[WRN] message from mon2 was stamped 12.271440s in the future clocks
not synchronized"
But i have synchronized my clocks 1 min befor with the same ntp-server..
----------------------------
The second error is, that I can't create / start an qemu-image on the
ceph-filesystem. I want to start a kvm virtual machine with the
virt-manager.
I create an image with
"qemu-img create -f qcow2 Platte-qcow2.img 10G"
When I chose those image an want to start a virtual machine with that
image. The virtual machine never starts. It hangs on look for the "harddisk"
Creating an Image with virt-manager doesn't work. There is after 2-3
minutes a timout and I have to kill the virt-manager job.
Are there some experiences with this?
-----------------------------
The third error I got is the following shown in the /var/log/messages file:

Are those timeouts normal?
-----------------------------
The last error I got for today is the following:
http://pastebin.com/UmrCRuhq
This happend when I was creating a dummy file with:
dd if=/dev/zero of=meineDatei count=5000000
I hope it's not too much errors in one message, but I want to show them
all in one email for the better look if depending to each other ;)
Thanks for you help.
With best regards,
Christoph Raible
