Hi,all:
I 'm dong tests with firefly 0.80.4,I want to test the performance
with tools such as FIO,iozone，when I decided to test the rbd storage
performance with fio,I ran commands on a client node as follows:
Which kernel on the client? Can you try the trusty 3.13 kernel on the
12.04 client?
Wido
rbd create img1 --size 1024 --pool data (this command went on well)
rbd map img1 --pool data -id admin --keyring
/etc/ceph/ceph.client.admin.keyring
then unexpected thing happened,the client node crashed ,the screen
showed messages that with:
[ffffffffffffffffffffffffffff81077ae0]?flush_kthread _worker
and many other messages like that.
I have to stop the node and restart to make it work again.
similary thing happed when I tried to mount ceph FS with kernel driver .
I ran command as follows:
mkdir /mnt/test
mount -t ceph 192.168.50.191:/ /mnt/test -o
name=admin,secret=AQATSKdNGBcwLhAAnNDKnH65FmVKpXZJVasUeQ==
the node also crashed and can't work any more ,then I had to restart the
node .
I 'm puzzled about the problem,I wonder if the problem lies in my linux
kernal or any other issues.Thanks for any help!
my cluster are made up of one monitor ,six osds and a client.
os:ubuntu 12.04 LTS
ceph version:firefly 0.80.4
yours sincerely,
ifstillfly
