Please check your tenant quota and calculate how much free space in Grizzly
cinder quota-show ${tenant-id}
cinder list

If you are using Havana, there is a convenient command “cinder quota-usage”

Hello again guys, I'm trying to overcome another issue with cinder, I'm here trying to create e 500 GB volume, this is my disk:

pvscan
  PV /dev/sdb1   VG cinder-volumes-2   lvm2 [931,51 GiB / 531,51 GiB free]
  Total: 1 [931,51 GiB] / in use: 1 [931,51 GiB] / in no VG: 0 [0   ]

But when I try:
cinder create --volume_type lvm_one --display_name v2st3-500 500

I get:
ERROR: VolumeSizeExceedsAvailableQuota: Requested volume or snapshot exceeds allowed Gigabytes quota

Does anybody know where I begin to fix it?

The outputs on cinder-api.log are:

ERROR [cinder.api.middleware.fault] Caught error: Requested volume or snapshot exceeds allowed Gigabytes quota

Hey :)
that means the volume is still in use. (lvopen : 1) make sure it's not by
checking the process, qemu-nbd, etc...

Do you know how I can remove all of them? When I try lvremove
/dev/cinder-volumes/volume-316f77c6-bf13-4ea4-9b98-028198f3922f, for
example, I get:

Thank you again.

Oh yah true!
not sure “conductors” exist yet for Cinder, meaning meanwhile, every node
needs a direct access to the database
glad to hear it’s working :)

Thank you so much, and if you need me just let me know.

Hello Razique, I got a couple of doubts, do you know if I need to do
something else that's is not on the link you sent me? I'm asking because I
followed the configuration but it's not working, here is what I get: I've
installed the cinder-volume at the second computer that have the HD, and
I've changed it's cinder.conf. I've changed too the master's cinder.conf
like is following:

[DEFAULT]
rootwrap
*config = /etc/cinder/rootwrap.conf sql*connection =
mysql://cinder:password@localhost/cinder
api*paste*confg = /etc/cinder/api-paste.ini

iscsi_helper=iscsiadm iscsi_helper = ietadm

iscsi
*helper = tgtadm volume*name_template = volume-%s

volume_group = cinder-volumes

verbose = True
auth
*strategy = keystone iscsi*ip
*address = 192.168.3.1 scheduler*
driver=cinder.scheduler.filter_scheduler.FilterScheduler
Rabbit authorization

rabbit
*host = localhost rabbit*port = 5672
rabbit*hosts = $rabbit*host:$rabbit
*port rabbit*use
*ssl = false rabbit*userid = guest
rabbit_password = password
rabbit*virtual*host = /nova

state
*path = /var/lib/cinder lock*path = /var/lock/cinder
volumes_dir = /var/lib/cinder/volumes
rpc*backend = cinder.rpc.impl*kombu

enabled

*backends=orion-1,orion-4 [orion-1] volume*group=cinder-volumes
volume
*driver=cinder.volume.drivers.lvm.LVMISCSIDriver volume*backend*name=LVM*
iSCSI
[orion-4]
volume
*group=cinder-volumes-2 volume*
driver=cinder.volume.drivers.lvm.LVMISCSIDriver
volume*backend*name=LVM_iSCSI


The cinder.conf on the second computer is like this but the IPs are
changed with the controller IP (It has the cinder-api), and when I run
service cinder-volume restart at the second computer it's status is
stop/waiting.

Any ideas?

Thanks :)

If I’m not mistaken, you only need to install the “cinder-volume’
service that will update its status to your main node
:)

Ok in that case, with Grizzly you can use the “multi-backends”
feature:
https://wiki.openstack.org/wiki/Cinder-multi-backend

and that should do it :)

ok !
what is your actual Cinder backend? Is it a hard disk, a SAN, a
network volume, etc…

Hello guys, I have a Grizzly deployment running fine with 5

nodes, and I want to add more storage on it. My question is, can I install
a new HD on another computer thats not the controller and link this HD with
my cinder that it can be a storage too?

The computer I will install my new HD is at the same network as

my cloud is. I'm asking because I haven't seen a question like that here.
Does anybody knows how to do that? Have a clue? Any help is welcome.

Thank you all.
