colikiall: have another issue with your scripts. it seems to me it's script related.00:10
colikiall: vm starting tries to connect to port 80 on
*** mattstep has quit IRC00:11
colikiall: iptables using dnat changes destination address to port 8773 on management node (8773 it's nova-api)00:11
colikiall: however the iptables also use SNAT to change the source address to compute nodes real public ip address00:12
*** afm has joined #openstack00:13
colikiall: nova-api on management node receives the request, treats it as received from real public ip address and searches the database for metadata for fixed_ip of real public ip address of compute node instead of vm's fixed ip00:13
colikiall: shouldn't the iptables only use DNAT to "redirect" to nova-api on compute node and not on managment node ? and avoid SNAT as well ?00:15
KiallIRC keeps popping over my movie ;) Damn you!00:16
coliI do apologise then and shut myself up :-)00:16

KiallAnyway - nova itself sets all those rules up, so either its something missing/wrong in nova.conf, or a bug in nova.. :)00:17

alexn6Hi! can smbody say - is it ok to for example ssh from running instance back to its public ip? (flatDhcp mode, 2 nics). One can ssh back to its private adrress, and look like all correct with iptables snat, but it still isn`t possible.10:06

*** tryggvil has quit IRC10:47

foexleso you cant login via public ip to your vm ?11:00
foexleor only from backnet to public ip?11:01
alexn6foexle: what exactly I want - nova-network on v.v.v.1,  VM on private v.v.v.2 has real IP r.r.r.r. I go to VM by ssh on real or private IP. and then form VM go to it again via real IP(via private it`s ok)11:01
foexleah yeah .... you need a extra nic in each vm11:01
foexlenormally you have a default route on your host server to access public ips11:02

jasonathere's a few suggestions in the openstack doco but wondering if anyone has gone through this recently.12:56
zykes-firstly for a starter setup12:56
reidraczykes-: you can have swift all in one machine12:56
zykes-isn't that a bit risky ?12:56
reidracit's a test setup12:57
reidrachow many zones do you want to implement?12:57
zykes-firstly 1 i guess12:57
zykes-i mean 1 server12:57
zykes-to see that it works12:57
reidracthen is all in one12:57
reidracyou need at least 3 zones if you want to use 3 replicas12:57

*** brainsteww has quit IRC12:58

reidracI see12:59
guaquayou can run with 2 replicas, 2 servers12:59
hugokuozykes , 1 pm , 5 disks12:59
guaquathe problem is, if 1 server dies, it's read-only12:59
hugokuozykes , two for system using RAID12:59
guaquaso it's basically down then12:59
hugokuothree disks for 3 zones12:59

Raziquezykes-: for which usage ?13:02
Raziqueah ok13:02
hugokuozykes , for which swift worker ?13:02
Raziquewouldn't misguide :)13:02

hugokuointernal using or ?13:03
zykes-hugokuo: web customers and archive system13:03
zykes-but not "heavy" public usage13:03
hugokuoI think it would be enough for a "storage node"13:04

hugokuoaround 8GB ram …. but I did not test it though13:04
hugokuoon of my deployment of swift with 6 storage node (desktop 4 core 16 G)13:06

jasonaand back to original question13:30
jasonaanyone had to buy this stuff and written or got access to a rfp/rfq/rfi ? :)13:30
jasonai'm particularly interested in how you asked vendors to supply storage around what nova needs, vs what swift needs.13:31
jasonahmm, quiet. :)13:33
*** osier has quit IRC13:35
JesperAHmm, in it suggests a Dell C2100 as a storage node, why not use a Dell R510/R515 for that? Much cheaper13:35

*** shaon has quit IRC13:37

guaquaahh, nice18:30
*** lionel has quit IRC18:30
guaquareplica count means how many zones a given file is18:30

guaquaand you put them into 4 zones18:33
zykes-4 servers yeah18:33
zykes-that's theoretically 4*12 nodes18:33
zykes-in "swift" terms18:33
guaquaso each zone consists of one physical server18:33
guaquai think a node is a server18:33
guaqua4 * 12 devices18:34

zykes-notmyname: i'm trying to make cost of hardware + cost gb/month19:11
notmynameyour opex will be determined by your DC (or whatever) space and the cost of people to keep it running (including replacing broken hardware)19:12
JesperAimpossible to say if we dont know your hosting costs19:12
zykes-notmyname: yeah19:12
zykes-but firstly i'm doing gb pr month based on server purchase costs19:12
notmynameisn't any per month cost entirely dependent on your operational setup (including your hosting costs)?19:13
zykes-notmyname: correct19:13
zykes-but i'm doing just servers purchase costs atm19:13

notmynameGlacee: depends on what you compare it to. :-) I haven't priced multi-PB SANs recently, but I hear they are expensive19:17
Glacee1PB to sell or 1PB before the copy of 3 files?19:17
zykes-with 3 nodes of 24*2TB nodes with 2*gig for storage net pr node19:17
notmynameGlacee: 1PB billable19:17
Glaceenotmyname: ah ok :)19:17
colizykes: to be on the safe side with investment consider your first capex cost as your loss and concentrate on opex and ebidta19:19
Glaceenotmyname: im around that number with the setup we are planning.. but that is with the crazy drives price right now19:20
Glaceeeven lower than that... propably due to more density that the cloudscaling setup19:20
notmynameGlacee: that's good to hear (it means "normal" prices are cheaper)19:20
Glaceebut.. thats prototyping.. :) we are starting with a lot less than 1PB :019:21
notmynamedrives dominate the cost of the cluster as it gets bigger19:21
Glaceeand my concercn is HDD vibration.. we will see how it holds up19:21

Glaceethats propably where the difference is with the cloudscaling 2TB setup19:22
notmynameGlacee: ya19:23
zykes-is that planned notmyname ?19:23

*** po has quit IRC19:23
zykes-+ "Multi-region support (Future - Not Started)"19:23
zykes-is a thing we would want :/19:23
notmynamezykes-: replication across a wide geographic area (ie with higher latency) is definitely on the "we need to figure this out" list19:24
notmynamezykes-: the large single objects handled  by the proxy rather than the client is planned, too. probably sooner than high latency replication (but I don't set the dev priorities, only try to argue what they should be)19:25
notmynamezykes-: we'd also be happy to review any patches submitted for these *hint*hint*19:26
Glaceenotmyname: the container replication between cluster.. I thought that was for the wide geo replication19:26
zykes-notmyname: how about say you have datacenter x then like 5-6 km away you have datacenter y ?19:26
zykes-is that "low latency" replication as well ?19:26
notmynameGlacee: ya, it's a start19:26
Glaceenotmyname:at least with that you can offer.. some kind of Multi-Region DR19:27
notmynamezykes-: ya, that's probably not an issue now (you may have to slightly adjust some timeout settings)19:27
zykes-what link is recommended ?19:27
Glaceewell I think.. does that include object replication between cluster?19:27
notmynamebetween the DCs? as big as possible ;-)19:27
zykes-notmyname: so 200 mbit isn't enough ? ;p19:27
notmynamezykes-: it could be. just depends on your use case :-)19:28
notmynameand how big you want your eventual consistency window to be19:28
zykes-is 3 zones sufficient for a start ?19:29
notmynameGlacee: container sync is a start to multi-geography clusters, but what I would like to see is one logical cluster that is able to span an ocean19:29
notmynamezykes-: only 3 zones doesn't give you any handoff zones in case of failure. I'd recommend starting with 4. 3 is minimum, 4 is better, 5+ is ideal19:30

zykes-sad that nova is taking the starlight ;p20:58
*** jkyle has quit IRC20:58
notmynameindeed ;-)20:58
notmynameactually, I think it's great they get a lot of attention. lots of people are interested in the cloud, and most people think "compute" when the hear "cloud"20:59
notmynameI think storage is fundamental20:59
*** jmckenty has joined #openstack20:59
notmynamebut nova has different challenges to face. some of which are because it gets so much focus from a diverse group of people21:00
Glaceeagreed.. if I check thenew "cloud" provider in my region.. their cloud is compute only21:01
notmynamebut as swift PTL, I think part of my job is to do some amount of "tech evangelism" for swift so we do get more people involved in contributing code to it21:01
GlaceeI think that object storage is the foundation of a webscale application21:02
zykes-how is "future-large-single-uploads" handled now ?21:02
zykes-and "future-searchable-metadata"21:02
Glaceethats why we started our project with object storage instead of compute21:03
*** jmckenty has quit IRC21:03
GlaceeI think to have a real cloud.. you need both really21:03
notmynamezykes-: implementing either one of those is up to the client now. for example, the client has to split the object and create the manifest. or the client can maintain a separate metadata store about the obejcts21:03
zykes-how is s3 doing it ?21:04
*** rustam has joined #openstack21:04
notmynameI'm not aware that they support either of those21:05
zykes-so if i wanted to store something larger then 5 gb today how is that handled ?21:06
*** rbp has joined #openstack21:06
notmynamezykes-: split the large object into chunks <5GB. upload them. then create a zero-byte file with the appropriate x-object-manifest header. when the manifest object is fetched, it will stream all the parts serially21:07
Glaceecontainers sharding.. interesting :)21:07
notmynameGlacee: ya, that should eliminate the practical limitation of containers with high cardinality21:08
*** redconnection has quit IRC21:09
JesperAContainers works like folders right? If i want to look up the filesize in PHP i can provide the link to the file in PHP and it would calculate it? Or do i have to store that kind of values in the database? (stupid question, i know, but i have to be sure).21:09
JesperAFrom a webserver to Swift storage that is21:09
notmynameJesperA: containers are only sortof like folders (in that swift only sorof has filesystem similarities--swift isn't a filesystem). technically, a container is a namespace within an account21:11
notmynameJesperA: the best way to get the size of an object is to HEAD the object and look at the headers21:11
*** redconnection has joined #openstack21:12
*** dysinger1 has quit IRC21:12
JesperAnotmyname ok so there is no real path to an object?21:12

Kiallzykes-: sounds like MogileFS terms? Moving from MFS?21:46
zykes-Kiall: like to "balance" data21:46
zykes-or does it do that automagically21:47
notmynamezykes-: the data is automatically balanced throughout the cluster (and rebalances itself as you resize the cluster)21:47
zykes-so say you change a drive21:48
zykes-in node x of 4 zones and you do that for each node in each zone21:49
zykes-then it ottomatically scales up ?21:49
zykes-but then it's like a raid, you need to scale up at least 1 node pr zone ?21:50
KiallWas handed 5 old-ish but not too old servers today and asked to take anything useful out.. So far I have 30x 250GB SATA150 HD's -_- Waste of effort undoing 120 screws!21:50

*** cereal_bars has quit IRC21:54
*** miclorb_ has joined #openstack21:54
*** catintheroof has quit IRC21:54
notmynameas you are adding devices to the ring, set the weight appropriately. a good start is to set the weight to the number of GB in each drive. for example, a 2TB drive can have a weight of 2000 and a 3 TB drive has a weight of 300021:55
notmynamethe weights don't mean anything except in relation to one another21:55
notmynameand it's used to ensure that heterogeneous drives grow evenly21:55
notmynameit also allows you do slowly fill or drain a particular drive (or group of drives) by slowly raising or lowering the associated weight21:56
notmynamefor example, when we add zones at rackspace, we add them over a period of time by raising the weights21:57

Kialljasona: you're not going to be able to articulate the workloads in an IRC chat ;) And the end of the day, you need to figure out what the users will be doing (in terms of CPU/RAM/disk I/O/network I/O etc) then size the hardware to handle that...22:11
Glaceejasona: hell no.. I would be a shame now their panderia release.. what a joke22:11
jasonakiall: the users can't give me that now22:12
Kiallthen you cant size the hardware accurately :)22:12
jasonakiall: and i have to take a stab at close enough, since this has to be ordered in 3 weeks..22:12
jasonaor it sets of a chain reaction that kills a bunch of project stuff :)22:12
jasonamaybe i can't do it accurately. can i try for 'in the same city' even if i can't get 'in the same ballpark' ?22:13
Kialllol, then you need to get in front of them and annoy them until they tell you what they need ;)22:13
Glaceeis 2^22 more reasonable or still crazy in your openion?22:13
notmynameGlacee: partition power of 30 would allow you to have a cluster with nearly 5000PB of _billable_ storage (at 80% full)22:13
notmynameassuming you use 2TB drives22:14
jasonakiall: they honestly can't give me more and they have no incentive to do that anyway.22:14
Glaceeyeah.. I realised that it was a crazy number after posting to the channel :)22:14
jasonathe cluster being built is being built partly to get them to look at this stuff and use it22:14
*** cloudgeek has joined #openstack22:14
jasonai.e get them interested in openstack and using the paas in the future. rather than the jillion small clusters around the place22:14
notmynameGlacee: 20 or 22 is quite reasonable for large clusters22:14
jasonaso with that in mind, taking a median approach, more feedback on hardware spec ? :)22:15
Kialljasona: then really, all you can do is guess.. start small. Since this is "get them to look at this stuff and use it", start with as little hardware as possible. Then you'll see what people really use.22:15
Glaceeyeah 41PB of billable storage with 2^2222:16
notmynameGlacee: 22 gives you 19PB of billable storage with 2TB drives22:16
Glaceeusing 3TB drives22:16
notmyname2**22 / 100 * 2000 * .91 * .8 / 3 / 2**2022:16
notmyname.91 is marketing to actual formatted size22:16
notmyname.8 is 80% full22:17
notmyname3 for replica count22:17
notmyname2**20 to convert from GB to PB22:17
notmyname.91 is ok for 2TB drives. it will be different for 3TB drives22:17
Glaceethanks.. I will keep that formula.. handy...22:17
Glaceeok I will check with 3TB22:18
Kialljasona: eg start with closer to commodity hardware.. eg 1Gb ethernet not 10g, you'll quickly see if there really is a need for 10g, of if more CPU is needed, that way - you have the budget left to upgrade etc22:18
notmyname3TB marketing == 3000000000 bytes unformatted. format and convert to bast 2 measurements to get the proper ratio22:18
*** nati2 has quit IRC22:20
Glaceefrom a few website it seems like .91 also for 3TB22:21
*** nati2 has joined #openstack22:21
GlaceeFormatted capacity 2.72TB22:21
notmynameVl2**22 / 100 * 2794 * .8 / 3 / 2**20 for 3TB (2794 is number of GB in a 3TB drive)22:21
*** rbp has left #openstack22:22
notmyname2**22 / 100 * 2794 * .8 / 3 / 2**20 = 29.80263824462891PB billable22:22
notmynameah ok. 2.72 formatted22:22
notmynamestill. 29PB22:22
Glacee52M/year at 0.15gb22:25
Glaceenot bad :022:25
notmynameheh :-)22:25
JesperAHow big is the biggest implementation of Swift?22:26
JesperA(biggest knowned)22:26
notmynameJesperA: "billions of files, petabytes of data" (unfortunately, that's all rackspace let's me say)22:26
KiallI would imagine Rackspace, but I doubt they give specifics...22:27
notmynamebut our clusters are larger than all the other published numbers I've seen22:27
Glaceeif they cluster reach that capacity.. thats what I call a Champagne problem :022:27
Glaceedo you think that 2^22 my be too slow if we start with around 140 devices?22:28
notmynameGlacee: the slowdowns associated with a larger ring size only come with updating the ring (which is done offline)22:29
notmynameGlacee: the other worry is the extra filesystem overhead for all the directory entries22:29
Glaceethanks again for your help.. that was instructive.. heading out22:30
notmynamehave a good day22:31
Glaceeyou too thanks22:31

colinotmyname: are you working in UK or US ?22:56
jasonakiall: i'm definitely looking at commodity for kit. just trying to differentiate22:56
jasonakiall: wondering how other people pick between dell vs hp vs ibm vs..22:56
colikiall: hi, in my opinnion your script needs change in ec2_dmz_host parametr in nova.conf , it should point to local compute node where nova-api is running and not to controler. if it points to a controler then instance is unable to communicate with (when compute node is on different host then controler)22:57
colijason: we use supermicro for years and didn't havy much problems. softlayer is using them as well in large numbers.22:58
colikiall: to be specific instance is able to communicate with (that is nova-api) but nova-api is unable to retrive metadata as the packets arrive with source address of the compute node and not of the instance.22:59
tjoyjasona: supermicro does make good gear23:01
jasonano argument there. but if they don't supply through existing gov contracts etc.. probably can't use them23:02
notmynamecoli: us23:03
tjoycoli: isn't 169.254.whatever a local address like ? am i missing something important?23:04
colitjoy: is being DNAT'ed to value of ec2_dmz_host and port 8873 (default unless set by parameter)23:05
coliupps port 877323:06
