| notmyname | suffix_dir is used to reduce the number of files in one directory | 01:55 |
| notmyname | by using the last 3 bytes as the name of the suffix_dir, you can be sure that there are only 4096 files in each directory | 01:56 |
| notmyname | the hash_suffix is added to the end of every hash lookup to prevent attackers from being able to generate many hashes that are close together and therefore on the same drive in your cluster (so keep the hash_suffix a secret) | 01:58 |
| notmyname | Oneiropolo: does that explain it sufficiently? | 01:58 |
| Oneiropolo | thanks | 02:05 |
| Oneiropolo | but how reduce the number of files in one directory. I can't get it now. | 02:05 |
| Oneiropolo | could you give me an example? | 02:06 |
| notmyname | the path on disk for every object includes the partition number | 02:07 |
| notmyname | the partition is defined by some number of prefix bytes of the hash of the object | 02:07 |
| notmyname | so, for example, let's say you used a partition size of 20 | 02:08 |
| notmyname | each hash is 32 bytes long (md5) | 02:08 |
| notmyname | so therefore it's possible to have 16**12 files in one partition | 02:09 |
| *** aliguori has quit IRC | 02:09 | |
| notmyname | filesystems tend to break when presented with those sorts of numbers, so by using the last 3 bytes as a "directory in the middle", we can be guaranteed that only 4096 files are in each directory | 02:10 |

| notmyname | actually, I misspoke | 02:19 |
| notmyname | it doesn't guarantee 4096 files per directory. it guarantees 4096 suffix dirs inside the partition | 02:19 |
| notmyname | so the path on disk looks like this: | 02:21 |
| notmyname | <data dir root>/<partition>/<one of 4096 suffix dirs>/<hash of object>/<object> | 02:22 |

| HugoKuo_ | I have a kvm raw image , Can I convert it for OPENSTACK NOVA ? what I need is cloud-init | 08:21 |
| HugoKuo_ | am I right ? | 08:21 |
| soren | HugoKuo_: You don't strictly need cloud-init in it. | 08:23 |
| soren | HugoKuo_: It should just work. | 08:23 |
| HugoKuo_ | so , I just add the raw image with Glance ? | 08:24 |
| HugoKuo_ | right XD | 08:24 |
| HugoKuo_ | It's cool !!!! | 08:24 |
| soren | That's the idea, yes. | 08:25 |
| HugoKuo_ | Thanks u so much . I got write a article about P2V tomorrow | 08:26 |
| soren | Cool :) | 08:27 |
| HugoKuo_ | cloud-init is for eucalyptus and amazon instance to retrieve , I'm interesting about how nova instance get it's metadata ,such as instance-ID , ssh_rsa without cloud-init | 08:28 |

| soren | HugoKuo_: It doesn't. | 08:33 |
| soren | HugoKuo_: That's what I'm saying. You don't strictly need cloud-init, because your instance can run perfectly fine without knowing its instance-ID. | 08:34 |
| soren | HugoKuo_: Or without grabbing ssh keys from metadata (if you already put them in the image). | 08:34 |
| soren | etc. | 08:34 |

| ianmp100 | hello, i was wondering what the best practise for extending an existing cluster is. For example say if i had a five zone production cluster (say about 1 PB) in size and I wanted to increase it to 2 PB, is it better to add more drives to each node in each zone or is better to create new zones. Is there a recommended maximum size for a zone? | 10:59 |

| radeck | Hi I'm little bit confused with where are the instances files are stored I can see them in /var/lib/nova/instances/ does it mean they always on local storage of the host ? Can Swift be used for storing instance folders ? | 11:37 |
| radeck | I've seen live migration docs but thats only exporting it from one of nodes If I want them to be HA should I consider some shared storage like NFS or ClusteredFS ? | 11:38 |
| *** katkee has quit IRC | 11:40 | |
| soren | radeck: Swift is object storage. Not block storage. I cannot act as a backend for virtual machines. | 11:42 |
| radeck | ok so I can't use Can Sheepdog be used for storing instances ? | 11:43 |
| radeck | I think I've seen somewhere support in Openstack for it | 11:44 |
| *** ctennis has joined #openstack | 11:44 | |
| *** ctennis has joined #openstack | 11:44 | |
| soren | radeck: Yes, you can use sheepdog. | 11:44 |
| soren | radeck: ...but probably not in the way you think. | 11:44 |
| soren | radeck: Are you familiar with EC2 or will their terminology only confuse this conversion further? :) | 11:45 |
| radeck | yep just reading about it its for volume-manager backend | 11:45 |

| *** karmabot has quit IRC | 11:45 | |
| radeck | I was just wondering why running instances are local on every node | 11:46 |
| soren | radeck: Ok. So openstack can use sheepdog to provide the EBS-like storage. | 11:46 |
| soren | radeck: ..but the instance storage is always local. So far. | 11:46 |
| radeck | ok | 11:46 |
| radeck | thats what I was wondering about | 11:46 |
| *** OpenWeb has quit IRC | 11:46 | |
| radeck | putting it on some kind of shared storage will still not ensure HA ? | 11:47 |
| soren | The common thinking is that you shouldn't rely on any single instance for your service to keep functioning. | 11:47 |
| radeck | OK so you would bypass that by running instances on different nodes | 11:48 |
| *** popopom has quit IRC | 11:49 | |
| radeck | so there is no way to setup nodes which would share same /var/lib/nova/instances folder | 11:49 |
| radeck | and if one of nodes dies second will pickup running instaces ? | 11:50 |

| newopen | who know why? | 16:23 |
| *** lvaughn has quit IRC | 16:24 | |
| kbringard | newopen: there are any number of reasons | 16:24 |
| kbringard | I'd check the nova-compute.log | 16:24 |
| *** ccustine has joined #openstack | 16:27 | |
| newopen | Kbringard:http://paste.openstack.org/show/1490/ | 16:28 |
| kbringard | I've never seen that error before, but that would definitely be your problem | 16:29 |
| kbringard | my guess would be you're running on a 32-bit architecture | 16:30 |
| kbringard | but again, I really don't know | 16:30 |
| newopen | it works before in the same machine | 16:32 |
| *** jedi4ever has joined #openstack | 16:32 | |
| *** mgoldmann has quit IRC | 16:33 | |
| kbringard | what size instance are you trying to launch? perhaps you've never launched one with more than 2GB of ram before? | 16:33 |
| newopen | tty one | 16:34 |
| newopen | i used the same before!! | 16:34 |
| kbringard | https://bugzilla.redhat.com/show_bug.cgi?id=581376 | 16:34 |
| kbringard | that looks like your problem, but again, I've never seen that error before, so I'm not really sure | 16:34 |
| kbringard | but, your problem appears to be in libvirt | 16:35 |
| kbringard | no idea why it worked before and not now though :-/ | 16:35 |
| kbringard | try your launch command with -t m1.tiny | 16:36 |
| kbringard | the m1.small instance type which is default allocates 2048MB of RAM | 16:37 |
| kbringard | so, I'm reading this page: http://wiki.openstack.org/XenServerDevelopment | 16:39 |
| kbringard | I assume it relies on you having a working XenServer install already? | 16:39 |
| kbringard | like, a Xen kernel on your dom0 and stuff? | 16:39 |
| kbringard | because it doesn't mention anything about getting all that installed | 16:39 |
| kbringard | or perhaps a better question would be: is there a good document on getting OpenStack running using Xen as they hypervisor? | 16:40 |

| *** jdurgin has joined #openstack | 16:57 | |

| OpenWeb | Hello guys, i have a question. I ‘m setting up nova installation using glance. And I configured glance to store images on swift. I had installed swift on a single node using the SAIO instructions. But I can’t upload new images ( image stat = uploading and size =0). I guess it’s because swift answers to all the requests using the loopback address. So how can I change the swift | 17:30 |

| kbringard | problem is, the nova stuff installex libxen3, which conflicts with the xen4.1 package on there | 20:28 |
| *** lborda has quit IRC | 20:29 | |
| kbringard | I wonder though, if whatever comes in the deb will work in it's stead, if I just remove it with nodeps | 20:29 |
| btorch | kbringard: yeah ... my next step was going to use a box for Xen.org host by itself and then use a separate one for the nova stuff | 20:29 |
| kbringard | yea... maybe I just need to blast this machine and start with just xen | 20:30 |
| kbringard | doesn't the libvirt that comes with nova have some custom patches applied? | 20:30 |
| btorch | kbringard: the other issue I remember was trying to figure out what xen api url to use with nova... | 20:31 |
| jatsrt | kbringard: I have to aks, why Xen over KVM? | 20:31 |
| jatsrt | or even ask | 20:31 |
| kbringard | well, I have it running with KVM | 20:31 |
| kbringard | but, it has some limitations | 20:31 |
| kbringard | like, when you assign an EBS volume, it ignores a defined block device and just assigns it to the next available one | 20:32 |
| kbringard | and, currently because OpenStack relies on virtio with KVM, you can't run KVM fully virtualized | 20:32 |
| kbringard | (which is why I was asking vishy about it earlier) | 20:32 |
| jatsrt | makes sense | 20:33 |
| kbringard | but I have some images that are provided by a vendor that can't use paravirtualization | 20:33 |
| kbringard | but they claim to support Xen | 20:33 |
| kbringard | so, for all of those reasons | 20:33 |
| kbringard | plus | 20:33 |
| kbringard | when people ask me "Why'd you choose X hypervisor" | 20:33 |
| kbringard | I want to have a better answer than "Well, it's what was default and it worked" | 20:33 |
| kbringard | hehe | 20:33 |
| jatsrt | "because I tried them all" | 20:34 |
| kbringard | zactly | 20:34 |
| kbringard | so at this point I'm just testing the waters with Xen | 20:34 |
| kbringard | or, trying to, I should say | 20:34 |
| *** OpenWeb has quit IRC | 20:34 | |
| kbringard | the biggest problem is, OpenStack seems to work best on Ubuntu, but Ubuntu has little to no Xen support | 20:34 |
| jatsrt | yep, they have put all their efforts into kvm | 20:35 |
| kbringard | even the xen packages that are included in 10.10 (3.3) have broken deps (xen-tools) and won't install | 20:35 |

| kbringard | and I didn't think to change the damn libvirt template | 20:46 |

| kbringard | thanks soren | 20:46 |
| soren | Sure. | 20:46 |

| deva | Hi.. I am installing openstack in RHEL6.1 and facing the problem of not able to connect to VM instance. I figured it out that iptables is culprit.As I disable it, I can connect ot VM instance .I need to describe my setup.I am installing single node openstack setup with eth2 as my external interface and br100 is connected to eth0 interface.I am using flatDHCP networking. | 21:48 |
| *** fysa has quit IRC | 21:48 | |
| deva | These are the IP rules I nees to comment out to make that work. -A INPUT -j REJECT --reject-with icmp-host-prohibited | 21:49 |
| *** galstrom has quit IRC | 21:50 | |
| deva | Please let me know if anyone faced similar problem and what might be the probable reason for this | 21:50 |
| deva | lemme know Thanks for your time | 21:50 |
| vishy | deva: i haven't seen this problem | 21:51 |
| vishy | where are you connecting from? | 21:51 |
| deva | From host machine to VM instance.I can see the VM instance is sending DHCP request and no reply is sent back to it. | 21:52 |
| deva | If remove that rule and restart the firewall, it works though | 21:52 |
| deva | Did u install openstack in RHEL? | 21:53 |
| *** gondoi has quit IRC | 21:53 | |
| *** fysa has joined #openstack | 21:55 | |
| vishy | deva: no, but it has been done | 21:56 |
| vishy | deva: so the dhcp reply from nova-network doesn't make it back? | 21:57 |
| vishy | fwiw on a single node you don't need to bridge br100 into eth0 | 21:57 |
| vishy | i don't really comprehend why that rule would be stopping dhcp replies | 21:58 |
| deva | vishy: ok, if You have any idea, can you tell me how might the firewall blocking the DHCP request and reply message. Ok but will it harm if br0-->eth0 | 21:58 |
| vishy | the only thing that i have seen doing that is ip address conflicts | 21:59 |
| deva | vishy:ok | 22:00 |
| vishy | seems odd that that rule would have any bearing on dhcp | 22:00 |
| vishy | dhcp goes out the broadcast address | 22:00 |
| *** BinaryBlob has quit IRC | 22:01 | |
| devcamcar | vishy: got distracted during last part of meeting - i proposed dashboard become an official project. any idea when the process for that will be figured out? | 22:03 |

| *** lucasnodine has joined #openstack | 22:06 | |
| dubsquared | devcamcar: i think that is discussed in the PPB meeting, different than the openstack team meeting. | 22:09 |
| dubsquared | i could have some wires crossed though, just throwing that out there in case it's right :D | 22:10 |
| *** lborda has quit IRC | 22:10 | |
| deva | vishy:you are rt. DHCP request is a broadcast message, but reply isn't . If you have any idea, can you tell me in flatDHCP mode what all the IP rules, that involve in forwarding the DHCP reply message to VM instance | 22:10 |
| vishy | devcamcar: it is on the agenda for the ppb meeting right? | 22:11 |
| devcamcar | vishy: yes, just checking in on when that is | 22:11 |

| *** hggdh has quit IRC | 22:12 | |
| *** agarwalla has quit IRC | 22:12 | |
| vishy | deva: the only time i've had dhcp messages failing is when br100 gets ips in the wrong order | 22:13 |
| *** hggdh has joined #openstack | 22:13 | |
| vishy | because there is a special exception to allow dhcp traffic and it has to come from the right ip | 22:14 |
| *** mattray has quit IRC | 22:15 | |
| deva | vishy:can you explain what does it mean br100 gets ips in wrong order | 22:15 |
| vishy | br100 ends up with multiple ips in flatdhcp mode | 22:15 |
| vishy | it gets the ip that was originally on eth0 and the ip address for the dhcp server (usually 10.0.0.1 | 22:16 |
| *** katkee has joined #openstack | 22:16 | |
| vishy | if those ips are in the wrong order, or if there is a conflict between the vm ips and the host ips | 22:16 |
| vishy | i have seen dhcp fail | 22:16 |
| vishy | this is all assuming that it isn't a rhel specific problem | 22:17 |
| *** jatsrt has quit IRC | 22:17 | |
| deva | ok , I dont have such problem as eth0 isn't having any IP address at all. hope its not a RHEL6.1 issue | 22:17 |
| vishy | what ip is on br100? | 22:18 |
| vishy | and what ip is on eth2? | 22:18 |
| deva | br100 -10.3.1.1 and eth2 10.0.1.3. | 22:19 |
| kbringard | hey Vish, while you're here... I'm looking to remove the virtio stuff from the libvirt.xml.template for the block I/O... should I just change the set to say scsi instead? | 22:19 |
| kbringard | just like does for Xen, and still leave the prefix as vd | 22:19 |
| *** vernhart has quit IRC | 22:19 | |
| vishy | deva: that sounds troublesome, you are using the 10.x range for both | 22:20 |
| vishy | deva: it is probably snatting that is causing problems | 22:20 |
| deva | -A nova-network-snat -s 10.0.0.0/8 -j SNAT --to-source 10.0.0.1 , its causing failing to get connected to external network as u can see 10.0.1.3 is my external IP | 22:20 |
| vishy | what is the value of --fixed_range? | 22:20 |
| deva | address | 22:20 |
| deva | 10.3.1.0/24 | 22:20 |
| vishy | so you need to set --my_ip=10.0.1.3 | 22:20 |
| vishy | --fixed_range=10.3.1.0 | 22:21 |
| vishy | er --fixed_range=10.3.1.0/24 | 22:21 |
| deva | I didnt set --my_ip=10.0.1.3 manually script did it . | 22:21 |
| vishy | and flush iptables rules (including nat rules) | 22:21 |
| vishy | yes you should though | 22:22 |
| deva | Sorry I didnt get you | 22:22 |
| vishy | set both of those | 22:22 |
| vishy | in your flagfile | 22:22 |
| deva | You want me to flush the ip rules | 22:22 |
| vishy | then flush all iptables rules | 22:22 |
| *** foxtrotdelta has quit IRC | 22:22 | |
| vishy | and restart nova-network | 22:22 |
| deva | --fixed_range=10.3.1.0/24 --my_ip=10.0.1.3 these both contain those values already. | 22:23 |
| deva | u want me to still restart | 22:23 |
| deva | please explain | 22:24 |

| larissa | deva: Error: "vishy" is not a valid command. | 22:26 |
| vishy | you're snatting rule is wrong | 22:27 |
| vishy | so perhaps it is an old rule from a previous run? | 22:27 |
| deva | is it .?. how to make this work.can you lemme know when does rules change and where will be they stored in /etc/sysconfig/iptables or /etc/sysconfig/iptables.save | 22:28 |
| deva | in my host machine, I got rules in both these files | 22:29 |
| deva | Sorry this rule is -A nova-network-snat -s 10.0.0.0/8 -j SNAT --to-source 10.3.1.1 | 22:29 |
| deva | eventhen its wrong | 22:30 |

| vishy | neither | 22:38 |
| vishy | they are not saved | 22:38 |
| vishy | and that rule is wrong | 22:38 |
| deva | if you know, please lemme know when does modifying IP rules occurs. and which files are accessed. like iptables.save or iptables | 22:40 |
| deva | should those both files contain same rules.? | 22:40 |
| vishy | don't look in the files | 22:41 |
| vishy | look at the actual active rules | 22:41 |
| vishy | iptables -L -n -v or iptables -S | 22:41 |
| *** johnpur has quit IRC | 22:45 | |
| deva | I need to as the output needs to be consistent after reboots. As I already said I am unable to connect the external network due to this rule -A nova-network-snat -s 10.0.0.0/8 -j SNAT --to-source 10.3.1.1 in iptables file.But in iptables.save this is -A nova-network-snat -s 10.0.0.0/8 -j SNAT --to-source 10.0.1.3. | 22:45 |
| *** RobertLaptop has quit IRC | 22:46 | |
| *** MotoMilind has joined #openstack | 22:46 | |
| *** robbiew has quit IRC | 22:46 | |
| deva | I donno why they are different , when rebooted, rules from iptables.save are taken and I can ping to external network but not to VM instance. | 22:46 |
| vishy | sigh | 22:47 |
| vishy | both of those rules are wrong | 22:47 |
| vishy | flush the tables, then restart | 22:48 |
| vishy | nova-network | 22:48 |
| vishy | then you can manually save them | 22:48 |
| vishy | 10.0.0.0/8 should be whatever --fixed_range is set to | 22:48 |
| deva | you are saying in my case as --fixed-range=10.3.1.1/24 , so rule should be -A nova-network-snat -s 10.3.1.0/24 -j SNAT --to-source 10.0.1.3 | 22:50 |
| deva | please confirm | 22:50 |
| vishy | yes | 22:50 |
| vishy | but i'm also saying that nova-network should create that rule when it starts | 22:51 |
| vishy | so if it isn't there is something wrong | 22:51 |
| kbringard | soren: that worked great, thanks! | 22:51 |
| *** kbringard has quit IRC | 22:51 | |
| deva | in flatDHCP mode is it necessary that br100 should be created manually. and Ip be assigned to it. I am not doing that manually. when VM instance is created, nova-network is doing that for me.Hope thatz not the problem | 22:53 |
| vishy | no | 22:57 |
| vishy | that is wrong | 22:57 |
| vishy | br100 only needs to be created manually in flat mode | 22:57 |
| deva | ok . then I guess what I did is right then.. not creating br100 manually in flatDHCP mode. donno what is causing problem for nova-network not able to update firewall rules appropriately | 23:00 |
