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 Somnath From: ceph-users [mailto:ceph-users-boun...@lists.ceph.com] On Behalf Of Mavis Xiang Sent: Thursday, June 16, 2016 1:47 PM To: ceph-users@lists.ceph.com 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.

Can anyone please give some insights about this problem? Any help would be appreciated! Thanks!
