Re: rbd ioengine for fio

[Somnath Roy <Somnath.Roy@xxxxxxxxxxx>]

What is your fio script ?

 

Make sure you do this..

 

1. Run say ‘ceph-s’ from  the server you are trying to connect and see if it is connecting properly or not. If so, you don’t have any keyring issues.

 

2. Now, make sure you have given the following param value properly based on your setup.

 

pool=<ceph-pool-name>

rbdname=<rbd-image-name>

 

Thanks & Regards

Subject: [ceph-users] rbd ioengine for fio

 

Hi all,

I am new to the rbd engine for fio, and ran into the following problems when i try to run a 4k write with my rbd image: 

 

 

rbd_iodepth32: (g=0): rw=randwrite, bs=4K-4K/4K-4K/4K-4K, ioengine=rbd, iodepth=32

fio-2.11-17-ga275

Starting 1 process

rbd engine: RBD version: 0.1.8

rados_connect failed.

fio_rbd_connect failed.

 

It seems that the rbd client cannot connect to the ceph cluster. 

Ceph health output:

cluster e414604c-29d7-4adb-a889-7f70fc252dfa

     health HEALTH_WARN clock skew detected on mon.h02, mon.h05

     

But it should not affected the connection to the cluster. 

Ceph.conf: 

[global]

fsid = e414604c-29d7-4adb-a889-7f70fc252dfa

mon_initial_members = h02

mon_host = XXX.X.XXX.XXX

auth_cluster_required = cephx

auth_service_required = cephx

auth_client_required = cephx

filestore_xattr_use_omap = true

osd_pool_default_pg_num = 2400

osd_pool_default_pgp_num = 2400

public_network = XXX.X.XXX.X/21

 

[osd]

osd_crush_update_on_start = false

 

 

 

Should this be something about keyring? i did not find any options about keyring that can be set in fio file. 

Can anyone please give some insights about this problem?

Any help would be appreciated!

 

Thanks!

 

Yu
