Hi Ceph-users.
I have an issue with my new Ceph Storage, which is backend for OpenStack (Cinder, Glance, Nova).
When I test random write in VMs with fio, there is a long delay (60s) before fio begin running.
Here is my script test:
fio --directory=/root/ --direct=1 --rw=randwrite --bs=4k --size=1G --numjobs=3 --iodepth=4 --runtime=60 --group_reporting --name=testIOPslan1 --output=testwriterandom
It is so strange, because I have not ever seen this method when I test in Physical machine.
My Ceph system include 5 node, 2 SAS 15k per node, I use both journal and Filestore in one disk, Public Network 1 Gbps/Node, Replica Network 2 Gbps/Node
Here is my ceph.conf in node compute:
Could you help me solve this issue?
Thanks and regards.
