[Openstack] SAN and Fibrechannel with OpenStack
dear openstack godfathers; I do plan to migrate from crappy vmware and some ibm based cloud stack to openstack and kvm. here's the thing: I am lucky enough to have decent hardware, all the compute nodes are interconnected via fibre channel. so I don't want and don't need iscsi. do you think I can make it with something like clvm? I read through the docs of openstack, but I am not really sure now if I can make clvm fly without hacking around in openstack (and nova-volume) too much, especially when it comes to live migration and so on... I realize OpenStack was not built for SAN and FC, but I would really like to hear your opinions on that.

Re: [Openstack] SAN and Fibrechannel with OpenStack
Thank you for your answer, I am not saying that I need a clustered filesystem, with clvm I just have all lvm-volumes available on all machines, but only one machine would attach to the filesystem of a specific LV at a time. On 05/17/2012 05:07 AM, Narayan Desai wrote: I'm not sure that it would be particularly easy to make nova-volume support clustered filesystems; the current model only supports attaching a volume to a single instance at a time. Aside from that, it shouldn't be too hard to use fc as the data path instead of iscsi. We're looking at using iSER in a similar capacity. -nld On Wed, May 16, 2012 at 4:05 AM, Wolfgang Hennerbichler wrote: dear openstack godfathers; I do plan to migrate from crappy vmware and some ibm based cloud stack to openstack and kvm. here's the thing: I am lucky enough to have decent hardware, all the compute nodes are interconnected via fibre channel. so I don't want and don't need iscsi. do you think I can make it with something like clvm?

Hi Diego,
Thanks for your answer. I will definitely give openstack a try. Not only
a try, I will try to make it work.

Hi Wolfgang,
latest versions of our distro supports NFS as backend storage for
instances, volumes and images. Basically a zone shares the same NFS
mountpoint for instances and another mountpoint for volumes, and I guess
it does not differ a lot from what you want to do with FC or iSCSI.
It's in our immediate roadmap to use FC and iSCSI instead of NFS, but
may be you can give a try to our NFS stuff until then ;-)
Cheers

[Openstack] nova-network not writing into dnsmasq-config-file
Hi openstack-guys, using the latest essex release from ubuntu packages, I see a weird nova-network behaviour (flat networking): nova.conf: --flat_interface=eth0 --flat_network_bridge=bridge_130 --flat_network_dhcp_start=192.168.32.130 --flat_injected=False nova-network runs on a different host as nova-compute. when I provision a VM, it all looks good (no errors in the logs), but the VM doesn't get an IP address. I've tcpdumped and verfied that the dhcp request reaches the correct interface of nova-network. now looking into dnsmasq I found this in the syslog: Jul 22 22:29:27 localhost dnsmasq-dhcp[3107]: read /var/lib/nova/networks/nova-bridge_130.conf Jul 22 22:29:50 localhost dnsmasq-dhcp[3107]: DHCPDISCOVER(bridge_130) 192.168.122.96 fa:16:3e:60:92:a6 no address available bummer. so I checked to see why this happens, and it turns out, that /var/lib/nova/networks/nova-bridge_130.conf is empty. I assume there should be the mac to IP mapping, written by nova-network, but although the file exists, it doesn't have content. nova-network doesn't complain about any issues with this file, the file system permissions allow the nova-user to write there, so I do not quite know how to handle this.

Re: [Openstack] Incremental Backup of Instances
You could solve something like this with bacula incremental backups, I'm doing this (but not with openstack) like this: make an lvm snapshot (or qcow2 snapshot) of the instance, write a script that mounts the filesystem and let bacula back it up (incrementally). bacula can do the actual snapshotting and mounting, so you don't need to coordinate when to create a snapshot and so on. this works very well, but is hard to configure, too. to restore the machine, one creates a lv in my case and restores the whole filesystem there. This works very well for linux vms, might be harder with windows vms. Wolfgang On 07/23/2012 05:22 AM, Kobagana Kumar wrote: Hi All, I am working on *Delta Changes *of an instance.

hi, running openstack essex with vlan-networking: --network_manager=nova.network.manager.VlanManager --vlan_interface=bond0 --public_interface=bridge_130 --auto_assign_floating_ip=True all works great except for floating ips. the problem is, that the floating ips are assigned to eth0 instead of bridge_130.

Thanks, that's what I ended up doing (by intuition rather than knowledge)
yesterday. I didn't know about nova rescue either.
I think this is a Big Big room for improvement here. In the best case this
should be discovered automatically and the switchover should be done without
human Intervention.

[Openstack] horizon: problems with upgrading to folsom
dear openstack enthusiasts, I've done it, I've upgraded to folsom. After a ton of troubles I've gone through and struggling to find documentation on how to UPDATE to folsom instead of installing from scratch I'm in a state where horizon is working again - well, almost. Before anybody asks: yes, I've issued *nova-manage db sync*. The instances list in horizon shows all the instances of a tenant including private and public ip addresses. But when I click on 'Access & Security' I don't see any floating ip's. Clicking 'allocate ip to project' brings up: 'no floating ip pools available. doing the same on the command-line: nova-manage floating list | head 7edc3284f53f4e02b92d498db41b842d19x.x.x.129 49c9d4e0-8f38-49e8-863c-17a8d5cb77c6novabridge_130 36f376d27f5b47e4b234d4f23bd0d66919x.x.x.130 87b7707e-9623-46d7-bd51-bbde6bfc13dfnovabridge_130 835e8fcba1334fb6b9421e51638ec10619x.x.x.131 Nonenova bridge_130 seems to bring up the latest and greatest results.

[Openstack] folsom nova-compute error on snapshotted images?
hello again, after upgrading to folsom nova-compute dies the fabulous death while gaining information from qemu-images. the information-gaining process works for some images, and then we reach the image instance-005c, which also has a snapshot associated with it. let's see the difference: regular image file: qemu-img info instance-005d/disk image: instance-005d/disk file format: qcow2 virtual size: 4.0G (4294967296 bytes) disk size: 3.0G cluster_size: 2097152 backing file: /var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_4 (actual path: /var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_4) and now an image with a snapshot: computeNode1:/var/lib/nova/instances# qemu-img info instance-005c/disk image: instance-005c/disk file format: qcow2 virtual size: 2.0G (2147483648 bytes) disk size: 1.8G cluster_size: 2097152 backing file: /var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_2 (actual path: /var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_2) Snapshot list: IDTAG VM SIZEDATE VM CLOCK 1 d9a9784a500742a7bb95627bb3aace38 0 2012-08-20 10:52:46 00:00:00.000 the image with the snapshot kills nova-compute as we can see here: http://pastie.org/5098216 help is appreciated.

[Openstack] snapshots not working in folsom
hi, after I've upgraded to folsom snapshotting just stopped working. Horizon doesn't complain, the log doesn't complain, but the snapshot is reportedly not taken (snapshot file isn't created, and I don't see the process of qemu creating it). as I said, nova-compute on the server doesn't complain: Running cmd (subprocess): sudo nova-rootwrap /etc/nova/rootwrap.conf qemu-img snapshot -c fd5ab4d51e12435884c8a90f190f1f15 /var/lib/nova/instances/instance-00f3/disk from (pid=13330) execute /usr/lib/python2.7/dist-packages/nova/utils.py:176 Result was 0 from (pid=13330) execute /usr/lib/python2.7/dist-packages/nova/utils.py:191 Running cmd (subprocess): qemu-img convert -f qcow2 -O raw -s fd5ab4d51e12435884c8a90f190f1f15 /var/lib/nova/instances/instance-00f3/disk /var/lib/nova/instances/snapshots/tmpclLTZA/fd5ab4d51e12435884c8a90f190f1f15 from (pid=13330) execute /usr/lib/python2.7/dist-packages/nova/utils.py:176 any hints or suggestions?

Re: [Openstack] Ceph + Nova
Not being a nova expert, and not using ceph with nova, I can tell you that I've been testing ceph extensively and it seems to be like 'the thing made for nova'. it seems stable, it is reasonable fast and the features are unbeaten. but I wouldn't use it for hosting qemu-images in /var/lib/nova/instances, glusterfs would be better suited in that respect. I've tested it as a block device fully integrated into libvirt. give it a try! wolfgang On 11/21/2012 09:37 AM, JuanFra Rodríguez Cardoso wrote: > Hi everyone: > > I'd like to know your opinion as nova experts: > > Would you recommend CephFS as shared storage in /var/lib/nova/instances? > Another option it would be use GlusterFS or MooseFS for > /var/lib/nova/instances directory and Ceph RBD for Glance and Nova > volumes, don't you think? > > Thanks for your attention. > > Best regards, > JuanFra > > > ___ > Mailing list: https://launchpad.net/~openstack > Post to : openstack@lists.launchpad.net > Unsubscribe : https://launchpad.net/~openstack > More help : https://help.launchpad.net/ListHelp > -- DI (FH) Wolfgang Hennerbichler Software Development Unit Advanced Computing Technologies RISC Software GmbH A company of the Johannes Kepler University Linz IT-Center Softwarepark 35 4232 Hagenberg Austria Phone: +43 7236 3343 245 Fax: +43 7236 3343 250 wolfgang.hennerbich...@risc-software.at http://www.risc-software.at ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

[Openstack] nova ceph integration
Hi, I'm sorry if this has been asked before. My question is: can I integrate ceph into openstack's nova & cinder in a way, that I don't need /var/lib/nova/instances anymore? I'd like to have EVERYTHING in ceph, starting from glance images to nova-disk-images and volumes (cinder). And more important: Can this be done in a way so that my horizon-users can still use horizon (including snapshotting) without the need of abusing the command-line? :) I've read that cinder and glance are supported, but I didn't find much information on nova-disk-images and ceph. thanks for a reply wolfgang ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

[Openstack] Keystone & LDAP integration
Hi Folks, we're trying to set up keystone with ldap. so far, so good. we can authenticate. but we can not give the admin-user 'god'-rights. Through tweaks of the policy.json-file it's possible that the admin-user sees all tenants, but he doesn't get the 'admin' tab in horizon. Any help is really appreciated.

Re: [Openstack] Can not create snapshot
For anybody running into the same troubles: HTTPOverlimit basically meant that glance didn't have enough free space on it's drive (could have thought about that, but I didn't realice that glance was meant). And: http://docs.openstack.org/folsom/openstack-compute/install/apt/content/configure-glance-files.html this helped a lot.
