*** ndipanov has joined #openstack-cinder09:21
szblcsI'm completely n00b to OpenStack. Can I use Cinder without any underlying storage software (e.g. CEPH) and is Cinder production ready?09:21
dulekszblcs: You can use Cinder with LVM, NFS or GlusterFS backends.09:21
szblcsso I need a Linux machine with LVM and Cinder manages that?09:22
dulekszblcs: And according to OpenStack User Survey Cinder is running in 58% of OpenStack production deployments, so I think it is ready for production use.09:23
dulekszblcs: Yeah, normally people would use a machine with a lot of disks or even multiple machines.09:23
dulekszblcs: But in principle you're of course right.09:23
szblcsThis is my use case: I've got two Dell C6220 servers. With 8 nodes in total. Each node can have up to 6 SFF disks (they already have 12 CPUs and 96 GB of RAM).09:24
szblcsI'd like to use the HDD bays of these nodes. My idea is to run one VM on each node and let that VM manage all the 6 disks (with pass through or something).09:26
szblcsThis way I'd give some of the RAM and CPU to the storage virtual machines and use the rest CPU/RAM for other VMs.09:27
szblcsDoes that make sense?09:27
dulekszblcs: I assume you want to have a complete OpenStack deployment?09:27
szblcsyes, I'd prefer that09:27
*** jordanP has joined #openstack-cinder09:27
dulekszblcs: Then why isolate storage nodes in VMs? Just install cinder-volume and cinder-backup on storage nodes.09:28
dulekszblcs: And cinder-api and cinder-scheduler on a controller node.09:28
duleks/storage nodes/compute nodes.09:28
duleksorry ;)09:28
szblcsSo Cinder is just like an add-on to the OpenStack? I'm really n00b, sorry about that. With my previous VMware/ESXi experience it's kind of hard to wrap my head around the OpenStack world.09:29
dulekszblcs: It's an OpenStack service handling block storage.09:30
*** shyama has quit IRC09:30
*** Julien-zte has quit IRC09:31
dulekszblcs: Just install, let it connect to the DB and RabbitMQ, create endpoints in Keystone and everything should be fine. :)09:31
dulekszblcs: http://docs.openstack.org/liberty/install-guide-ubuntu/cinder.html09:32
szblcsand if I have 8 nodes in total and let Cinder manage my storage, will I have 8 small direct attached storage as a result or one large storage similiar to GlusterFS/CEPH?09:32
dulekIn the end you will be able to attach persistent volumes to your VMs.09:32
*** vgridnev has quit IRC09:32
dulekszblcs: You can create as many volumes as you have GBs in your storage pool.09:33
*** vgridnev has joined #openstack-cinder09:33
dulekIt's block storage, not a filesystem.09:33
dulekIf you want filesystem as a service you should take a look on Manila project.09:33
szblcsah, okay, thanks09:33
dulekTo explain more - Cinder can create virtual disks (block devices) in your storage pool. These disks can be attached to instances. That's simply it. :)09:35
*** haomaiwang has quit IRC09:37
*** haomaiwa_ has joined #openstack-cinder09:37
szblcsand can I attach a virtual disk running on a different host? (I can't do this in VMware)09:37
szblcsto a VM running on a different host09:38
dulekszblcs: Sure, by default it's done through iSCSI.09:38
szblcsok, thanks09:38
dulek(but I think we have also FC and NFS connectors)09:39

vincent_hougeguileo: a = b.get('index')      c = a, comparing to a = b.get('index')  c = b.get('index'),      so two of these ways are preforming the same, right?14:02

openstackgerritYuriy Nesenenko proposed openstack/cinder: Fix service-list filter  https://review.openstack.org/26325714:04
geguileoOn first case you call .get and it returns an object and then you copy a reference to that object to c14:04
*** merooney has joined #openstack-cinder14:04
*** alonma has joined #openstack-cinder14:05
geguileoOn second case you call .get twice (here is the difference in performance) and the result is the same, because a and c also have a reference to the same object14:05
geguileoThe get could be faster or slower depending on the b object14:05
vincent_houAH>>>>14:05
geguileoIf it's a dictionary you basically have a string hashing and a hash table lookup14:05

Thelo_smcginnis: Hi, regarding this patch https://review.openstack.org/#/c/267725/ its odd because it always fails at the same place and seem to be a timeout issue, however this patch that depends on the previous does not face the issue : https://review.openstack.org/#/c/253353/14:19

smcginnisRioX: I think the vmware_* settings need to go under the [lvm] section.14:33
RioXsmcginnis: okay let me try that then14:34
*** Julien-zte has quit IRC14:36
smcginnisRioX: It might also be less confusing to rename that from lvm to something like "vsphere" or the name of your vCenter.14:37
smcginnisRioX: Then change the line "enabled_backends = lvm" to "enabled_backends = vsphere"14:37
RioXsmcginnis: year you a right14:37
smcginnisRioX: And change "[lvm]" to "[vsphere]", then add the line under that section "volume_backend_name = vsphere"14:38

precursehey guys.. quick question. I've looked everywhere for this, but been unable to find any sort of answer. I'm using the latest version of icehouse right now, along with an Ubuntu 14.04 instance.  I've mounted a few cinder volumes to use for gluster storage within my VM. I've been testing some scenarios where I yank the cinder volume from the VM while running to see how gluster reacts. Linux, in17:14
precursegeneral, does not like this.17:14
openstackgerritTom Barron proposed openstack/cinder: Fix sluggish rbd unit tests  https://review.openstack.org/27092517:14
precurseIt appears to hang, since there's no notification that the volume was yanked.. and it appears the only way to fix it is a hard reboot17:15
*** alonma has quit IRC17:15
openstackgerritApoorva Deshpande proposed openstack/cinder: Tintri image cache cleanup  https://review.openstack.org/26837017:15
precurseI know it's not good to just yank a mounted volume, but I'm simply testing this for resiliency.. to make sure it will still work in that scenario17:17

tbarronare you unattaching from an instance (a vm)? or messing up the mount to the host?17:27

precurseunattaching it from the vm through the web ui17:28
openstackgerritApoorva Deshpande proposed openstack/cinder: Tintri image direct clone  https://review.openstack.org/26112617:28
*** alonma has quit IRC17:29
precurseseems that when you go to access the mount point after you've unattached it, the command hangs forever and is never notified that the disk is gone17:29
scottdaprecurse: Yes, that is what I would expect to happen17:29
precurseso things like md, zfs, gluster  all hang17:29
tbarronprecurse: you are trying to access the mount point from the host, or from the vm instance?17:30
scottdaprecurse: If you've mounted the volume inside the VM, then detach the volume while the vol is in use, it is likely that things like 'mount' inside the VM will hang.17:30

*** fthiagogv has joined #openstack-cinder17:31
precursefrom in the VM, it seems like anything that goes to read/write to the mountpoint after detaching the volume will hang though..  as though there's no notification that the volume was detached17:32
*** xyang1 has quit IRC17:32
*** alonma has joined #openstack-cinder17:32
precursewhereas in a physical sense, if I pull a physical drive from a system, it will notify17:32
*** fernnest_ has quit IRC17:35
precurseas an example.. if I create a raid volume with md (or zfs) with multiple cinder volumes inside a vm.. everything works. if I detach any single one of those drives, the entire array hangs since the subsystem just hangs waiting for the disk. If I do the same thing on a physical box with physical disks, it knows the disk was pulled and reports to zfs as a failure17:36

tbarronprecurse: so is what you describe independent of the fact that you are using glusterfs as backend for cinder?17:38
precurseright17:38
scottdaBut there is no mechanism for cinder out nova to alert the guest os.17:38
precurseit seems that linux itself doesn't notice a disk was detached17:38
precurseah17:38
*** esker has joined #openstack-cinder17:39
precursethat's what I was looking for17:39
tbarronprecurse: you would see that same with LVM backing the cinder vols, right?17:39
precurseI imagine so. We have one openstack setup with LVM backing it, and one with ZFS backing them.. Both are the same17:39
*** alonma has joined #openstack-cinder17:40
johnthetubaguyscottda: I wonder if thats something the qemu guest agent worries about? I assume it doesn't, but I am not sure17:40
precurseI know it's not good doing raid on top of raid.. it was just a test case more than anything17:40
tbarronprecurse: I think it's an interesting case.  IMO it is reasonable to do ZFS or btrfs "raid" inside a VM instance.17:42
scottdaprecurse: Yeah, in my soon-to-end role as a Public Cloud operator we had a similar problem with users doing raid on top of raid. Be strongly advised against it since it would cause this problem.17:42
tbarronwell, whether it is "reasonable" from a performance and robustness standpoint, i mean17:42
scottdajohnthetubaguy: Good question, I don't know.17:42
tbarronit is reasonable to be able to treat the VM instance as if it were standalone.17:43
tbarronscottda: not arguing with that advice BTW17:43
*** alonma has quit IRC17:44
scottdaIt seems the manila team was looking at ways to reach into the guest OS to do things like alter fstab and mount/umount. I'm not sure if they've gotten anything done there.17:44
scottdaprecurse: but is sounds like you are looking for a low-level alert to the guest OS17:47
precurseexactly17:47
*** alonma has joined #openstack-cinder17:47
precurseit's just a lot easier to see the issue it causes when using them in a fashion that should be resilient to failures17:48
scottdaYeah, I don't think we ever solved this for our customers who wanted RAID  inside their VMs, but I'll ask around for details.17:49

asselinSwanson, do you have any jenkins slaves? any nodepool nodes?20:36
Swansonasselin, no slaves.  This is your single node setup stuff.  My nodepool node is the same box as jenkins.  It has created and farmed off images to my cloud machine.20:38
Swansonasselin, presumably I can just delete the node: 'd-p-c' bit and let it run on anything it knows about which would be the local jenkins master, right?20:40

asselinSwanson, does nodepool list show anything?20:41

*** xyang has joined #openstack-cinder20:42
Swansonasselin, dib-image-list shows two "dpc" images and image-list shows two images of the same name.  (Provider is my cloud name.)20:43
asselinSwanson, right, those are the images. Are there any nodes built using those images? nodepool -h20:45
*** hyakuhei has quit IRC20:45
Swansonasselin, I'm sorry.  Missed your previous message.  provider: mdc-ci-cloud label: d-p-c  target: mdc-ci-zuul, etc.20:46

*** mragupat has joined #openstack-cinder20:47
asselinSwanson, ok, so you have a nodepool node that's not in jenkins, right?20:48
SwansonJenkins cannot seem to find that node.20:48
asselinSwanson, and you don't see it either in the jenkins UI?20:48
Swansonasselin, Jenkins ui shows only the master.20:49
asselinSwanson, ok, can you double check your settings in /etc/nodepool/nodepool.yaml20:50

Swansonasselin, another question if you're around.  The node is showing up in jenkins but is showing up as offline.  This appears to be a ssh issue.  I can login to it using the key used in nodepool.  And that key seems to be the same as in common.yaml...22:01
*** haomaiwang has joined #openstack-cinder22:01
asselinSwanson, yeah22:02
Swansonasselin, the key in common.yaml is the same key that nodepool is using, right?  jenkins_ssh_private_key?22:03

itlinuxany suggestions on what could be the issue to test it I installed allinone22:59
itlinuxthanks22:59
smcginnisitlinux: Hard to say just based on that.23:00
smcginnisitlinux: Something on the server side, but beyond that I don't know.23:00
hemnaitlinux, have to look in the c-api log23:00
itlinuxok where should I track this down.. all the cinder commands work23:00
*** mudassirlatif has quit IRC23:00
hemnait should say something other than the 500 error23:00
itlinuxI can create volumes attach etc..23:00
smcginnisitlinux: It could be in cinder, or it could be keystone.'23:00
hemnaif not, depending on the call, the real error could be in c-sched or the c-vol log23:00
itlinuxyeap23:00

itlinuxtanks for your help smcginnis23:01
smcginnisitlinux: It's possible without the debug level logging there might be something.23:01
smcginnisitlinux: That _should_ show up at the error level,23:02
itlinuxk23:02
smcginnisitlinux: so unless you have logging completely suppressed right now, I would hope there's at least some clue in the logs.23:02
*** lpetrut has quit IRC23:02
itlinuxno much there now23:02
smcginnisitlinux: But you may end up needing debug on to find the exact thing that caused it.23:02
itlinuxyea I will have to spend some time to track it down23:03
smcginnisitlinux: Yeah, there's usually a lot, so I would hesitate adding more until you need it. ;)23:03
