uksysadmincatbot, I had a brief look at it and couldn't get it going - can't remember now, it could even have been that the code wasn't ready! (~3 months ago)07:44
alex88yeah read some posts about him :)07:44
* uksysadmin is in da house!07:45
koolhead17alex88: whats new from your side07:45
alex88bad news, finished configuring openstack, now it's fully working, except that in one host, the vm has 700 as await in iostat and a simple apt-get install varnish takes minutes07:46
alex88that's strange because host has 12 as await07:46
alex88you? any good'07:46
uksysadminalex88, I was like that "bad news, finished configuring openstack, now it's fully working" - where's the fun when its not working!? ;-)07:46
alex88uksysadmin, eheh, the fun is later when the boss pretends it to be working :)07:47
catbotuksysadmin,the comment from says I should set API_provider, but no comment about how to do that. thanks anyway.07:48
koolhead17alex88: :P07:48
uksysadminalex88, that's been by ruse all along - "Honestly its working... well apart from x... oh and y... and well, that will be next release..." ;-)07:48

MadkissEmilienM: well, on a very simple level, the main problem currently is that starting nova-volume on nodeb will not export any volumes that were exported while it was running on node a, right?08:12
LesebI think the failover breaks the iscsi session? right?08:14
alex88uksysadmin, and no, no swap at all, 12gb ram free08:14
EmilienMthat's why I was thinking about multi pathing08:14

LesebMadkiss: if you want to use the nova.volume.driver.ISCSIDriver, a way or another you need to keep your iSCSI session reliable. This could be a nova internal mechanism or maybe managed by pacemaker. At this point of time we can try to think about a nova/cinder integration but for non-folsom or non-grizzly users try to think on a possible workaround with the current driver08:35
LesebEmilienM: I know the option, but never tested it. Each failover scenario are truly dependent on the driver in use :)08:36
EmilienMI think the best way is to try, isn't it ?08:37
*** bharata has quit IRC08:39

*** simon_lucy has joined #openstack08:42

melmothno idea kviiri :-( Btw , talking about vlan, who is using vlanmanager ? i m wondering if compute nodes needs also 2 nic on this case, or if one just flag packet on eth0 for floating and static networks.10:47
p3N74d4v1Dbtw melmoth do you have different physical servers10:48
p3N74d4v1Dor thay are all running on a single main server?10:48
melmothwell... i do all my stuff in kvm vms.10:48
*** Glace_ has joined #openstack10:48
melmothso they are different servers (1 manager, 1 messaging, 3 computes nodes);  but they are all hosted on one signle real bare metal box10:49
alex88melmoth, i'm using it10:49
melmothit makes no sense, except i can play and learn. but it s not usefull otherwise10:49
oneiroimelmoth heard you like KVM, so he put a kvm in your kvm so you can openstack while you openstack10:50
oneiroi /endpun10:50
melmothalex88, so, how do you do for compute nodes ? eth0/eth1 or eth0.101 eth0.102 ?10:50
p3N74d4v1Dlol oneiroi10:50
alex88melmoth, we've hosted servers, eth0 is public facing internet, eth1 is private network10:50
alex88melmoth, but give a try to vde, it's a virtual switch that you can attach to instances and then manage tagging, ports etc10:51
melmothohhh vde ? never heard of it. i did play with openvswitch but failed to to what i wanted10:51

swinchenThanks all the same.  I am sure it must be possible... otherwise that wouldn't scale so well :)14:26
melmothin theory you can still add a remote iscsi block device to your nova-volume node, add those in nova-volumes vg and re exporet them in iscsi to vm14:27

lipinski1more dhcp help necessary..  My VM is ignoring a DHCPoffer send from dnsmasq, but it accepts it from dhcpd that I started/configured manually.14:44
lipinski1Looking at packet traces, I see very few differences between the two DHCPOffers.14:44
zynzelswinchen: you have multiple nova-volume14:44
zynzelbut each nova-volume know about volumes 'on it'14:45
lipinski1e.g., TTL 64 vs 128, DiffServ set vs unset, etc.14:45
zynzelbut any compute node can attach volume from any other nova-volume14:45
*** ondergetekende has quit IRC14:45
swinchenzynzel: is this all automated?  Would I need to change the prefix on the new node?14:46
zynzelin essex you should change --iscsi_ip_address in volume node14:46
*** lloydde has quit IRC14:48
swinchenOk, but leave the target_prefix the same?   So if I have a bunch of 500GB nova-volumes, I could not create a 1000GB volume for an instance correct?  in other words... it doesn't pool?14:48
*** lloydde has joined #openstack14:48

zynzelswinchen: iscsi_ip_prefix flag is used only in one line in code, in xenapi14:49
zynzeland yes, you could not create volume 1TB witch many 500GB nodes14:50
swinchenI was thinking of this:
zynzelmaybe with clvm? but dont use it.14:50
zynzelswinchen: this is only prefix for iscsi names14:50
zynzelthere is no need to change it for many volumes.14:51
*** shang has quit IRC14:51
swinchenOk, hmmm... this is going to be a challenge.  :/  I think I need to find a different storage method.   We have a bunch of nodes with 1TB disks, and some of that used for OS/disk images/etc.   But we will want instances with more storage than a single node can provide.14:51
zynzelswinchen: read about ceph rbd14:52
zynzelor simply use external array14:52
swinchenYeah, we have an external array.  I think I might use nfs to store a large VG.   I will need to talk it over with the other admins I think14:53
swinchenThanks for the suggestions.14:53
zynzelswinchen: no, you cant use nfs as a nova-volume backend14:54

Mdev0ldave: also, I do not understand if the volume will appear to the guest as a block device or if the guest will have to internally mount it using iSCSI16:15
ev0ldaveit will appear to them as a block device16:16

Mdcan I use stock openstack to directly use iSCSI storage from a SAN?16:57
melmothMd what do you mean by "directly use" ?16:58
*** matwood has joined #openstack16:58
melmoththere s a nova-volume service that let you export some iscsi lv to remote virtuals machine16:59
Mdmelmoth: my SAN exports iSCSI LUNs and I make them available to nova volume to create pools16:59
Mdmelmoth: no, the point is that I already have somethign which exports iSCSI volumes16:59
Mdmelmoth: I just want to use these iSCSI block devices as storage pools17:00
melmothif your nova-volume beahave as an initiator of your san, it will have access to the remote block device as if they were local.17:00
ev0ldavei use open-iscsi17:00
melmothit can then use them to build a nova-volumes vgs, and use this space to act as a target for virtuals machines17:00

*** adalbas has joined #openstack17:00
ev0ldavemd:  i use open-iscsi to create local block storage for gluster and another for nova-volume group17:01
ev0ldavethat is setup outside of openstack17:01
Mdmelmoth: I am not sure I understand. what I meant is "can the compute node be the iSCSI initiators for my SAN?"17:01
ev0ldavemd: openstack just uses the block device once it is there17:01
*** kindaopsdevy has joined #openstack17:01
Mdev0ldave: but as we discussed earlier, I would need that third party add on to use a local block device17:02
Mdso I am still confused :-/17:02
melmothhmmm. Md, once they have booted, i guess they can , as long as there s a network access to your san.17:02
*** kindaopsdevy has quit IRC17:02
melmothbut if you want the thing to be handled with nova command, i guess you need to have the bloc device managed by nova-volumes17:02
*** kindaopsdevy has joined #openstack17:03
Mdmelmoth: actually I *want* to have block devices managed by nova-volumes, because this way I could use the on-board hardware initiators of my blade servers...17:03
Mdmelmoth: but ev0ldave says that I cannot directly use local block devices as persistent guest block devices17:03
*** warik has joined #openstack17:04
*** anniec has joined #openstack17:04
melmothall i know is, if you want your block devices attached with some nova-command, then they must comes from the nova-volume node (being the target)17:05
melmothbut this node itself can have access to them from a remote target17:05
*** anniec_ has joined #openstack17:05
Mdmelmoth: yes, I do not want to use intermediate nova-volume nodes since my compute nodes have access to the SAN17:05
ev0ldavemd:  the openstack uses iscsi to attach a volume to instances whether it is local or not.  that addon ii sent you allows the storage to be local on the compute node instead of having to be local on the nova-volume server.  from what i read it does .  the addon i sent you allow the instance to attach to the local block device but has caveats as listed in the blog17:06
*** darraghb has quit IRC17:06
*** kmwhite has joined #openstack17:06
ev0ldavewith that add-on, you do not need nova-volume but your volume is forever attached to the instance, at that point you might as well just provision the instance with the storage you need17:07

*** rnorwood has joined #openstack17:10
ev0ldave:-/ doh17:10
ev0ldavei have /var/lib/nova/instances mounted to a gluster accross my compute nodes, which uses iscsi attached to san as storage17:11
ev0ldavethat way i can do live migrations of instances between nodes and have redundancy17:11
Mdmy SAN is locally available to all compute nodes, which have built in hardware FC and iSCSI initiators. so everywhere I turn on an instance it will find the storage17:12
Mdwait, does openstack support live migrations? I was told by canonical that it does not17:12
ev0ldaveit does17:12
ev0ldavei use it to rebalance nodes periodically via cron17:12

*** nati_ueno has joined #openstack17:15
Mdev0ldave: OK, so the difference is that an attached volume usually comes over iSCSI, while local storage could be anything?17:15
UICTamalehey all, is anyone here using floating IPs on a local network?17:16
UICTamaleand if so, do you define any static DNS for them or does dnsmasq take care of it?17:16

ev0ldavei dont use swift17:17
ev0ldavesince i have a 7 TB msa i just use the raid on that17:17
ev0ldavewhat i lose not using swift is the redundancy of multiple proxy servers17:18

lipinski1zynzel: Took a full day to find it.  udhcpc on a client was sending DHCPDISCOVERs and dnsmasq sending DHCPOFFERs, but the DHCPOFFERs were dropped by udhcpc because of bad UDP checksum.19:42

lipinski1zynzel: dhcpoffer was send from dnsmasq (nova-network) on same host as nova-compute, so the packet simply traversed the bridge and never used the "real" NIC.  So, because, by default, bridge devices come up with tx-checksumming on, the UDP checksum was invalid19:45

*** linuxfreck has quit IRC19:51
zynzelgood luck to fix it without knowing where problem is.19:51
lipinski1zynzel: I would think that since nova uses dnsmasq, it should work with standard dhcp clients.  It doesn't if the client is udhcpc and nova-network and nova-compute are on same host, and tx-checksumming offload is enabled.19:52
zynzellipinski1: ok, and of course you test official uec image?19:52
zynzelmaybe it is bug in udhcpc?19:52
*** DavidLevin has joined #openstack19:52
lipinski1I know exactly where the problem is.  The host OS is using tx-checksum offload - so it is not calculating UDP checksums on packets - it's allowing the hardware NIC to do that.19:52

lipinski_ok - let me try that. But, I'm concerned that it will not adjust the offload parameters correctly on the bridge...21:14
