hi all

i am unable to create Cinder volumes

I have a 4 node set up at the moment controller1 compute1 network1 cinder1

I have followed the guide to install cinder on the controller1 node and have also followed the guide on the cinder1 node

here are the outputs of some of the commands that I have picked up

  --- Physical volume ---
  PV Name               /dev/sdb
  VG Name               cinder-volumes
  PV Size               50.00 GiB / not usable 4.00 MiB
  Allocatable           yes
  PE Size               4.00 MiB
  Total PE              12799
  Free PE               12799
  Allocated PE          0
  PV UUID               13h6Dp-wcLQ-28Om-2sC4-21sq-04zn-AcpAXG

  PV /dev/sdb   VG cinder-volumes   lvm2 [50.00 GiB / 50.00 GiB free]
  Total: 1 [50.00 GiB] / in use: 1 [50.00 GiB] / in no VG: 0 [0   ]

this is the error i am getting on the controller1 scheduler.log

 2014-12-10 13:14:14.033 1319 ERROR cinder.scheduler.flows.create_volume [req-af4f5ce6-e00d-4acd-995b-7fa9a0837580 0b188de927e34893acd94a489fb1e167 d0d944054e504a7eb2ab114c0de98d63 - - -] Failed to schedule_create_volume: No valid host was found.

can anyone point me as to where to look at here if required i can send my cinder.conf files hi, thanks for the reply

check cinder-volume status on cinder1 node. Also check cinder-volume logs on the cinder1 node to resolve the issue.

the cinder-volume returns a lot this is the only line i see as error it seems to point to mysql connection can i test that in anyway?

ImportError: No module named MySQLdb 2014-12-11 07:34:28.641 33168 ERROR cinder.openstack.common.threadgroup [-] No module named MySQLdb

OK I managed to get this going by installed pythonmysql from the juno install guide - odd i am installing icehouse but this seems to have resolved the issue connecting to the SQL database

thanks for the replies

Could you please provide us with the output of these commands in order to know the root cause of the issue?

  1. [root@openstack2 ~]# cinder service-list
  2. [root@openstack2 ~]# ll /var/lib/cinder/
  3. [root@openstack2 ~]# grep "var/lib" /etc/cinder/cinder.conf
  4. [root@openstack2 ~]# grep "cinder-volumes" /etc/cinder/cinder.conf
  5. [root@openstack2 ~]#mount
