* loicd listening to playback of tonight feed    03:30
loicd    ccourtaut: I'm breaking up sometimes ( not hearing what people say ) around 0:38 in . Do you experience the same problem ? If you listen from 0:38 to 0:39 without breaking up you don't have the same problem and it's just on my side ;-)    03:47
ccourtaut    loicd, oh you mean you don't hear sage but his lips are moving?    03:50
ccourtaut    he told yesterday he was sorry about that, we he types, it mutes, and it happens that he types while talking    03:51
ccourtaut    loicd, iirc    03:51
joelio    yea    03:51
loicd    ccourtaut: yes    03:51
loicd    oh, ok    03:51

loicd    yehudasa: I suggest that teuthology is made more friendly for non-inktank users as part of a better continuous integration    06:13
*** nwat has joined #ceph-summit    06:14
joelio    should the tenants be driven by a standard API (EC2, OCCI etc.?)    06:15
loicd    joelio: good idea :-) using euca2ools would make teuthology somewhat agnostic    06:21
joelio    :)    06:22
joelio    I use OpenNebula here, so anything that is cross-platform is win for me    06:22

rturk    I know sjustlaptop and loicd were listed as interested parties for the erasure coded storage backend session    07:26
rturk    anyone else?    07:26
scuttlemonkey    ccourtaut was going to take notes, so he should probably get an invite    07:27
rturk    ok    07:27
scuttlemonkey    so he's live and not delayed    07:27

rturk    hey just kidding about that pad link.  It's actually here:    07:34
mikedawson    loicd: My team will be able to be an alpha tester    07:40
loicd    mikedawson: excellent news :-)    07:40
sagewk    awesome!    07:40
joelio    loicd: me too, inherited a few more test nodes today    07:42
scuttlemonkey    joelio: hey, did you ever do that internal technote?    07:42
loicd    coool added to    07:42
joelio    scuttlemonkey: oh, much more than that - built the full platform :)    07:43
joelio    I guess the asnwer is yes, I can do a community post :)    07:43
scuttlemonkey    haha    07:43
scuttlemonkey    only if you have time/interest    07:43
rturk    :)    07:43
scuttlemonkey    I just remember you saying the technote would be an easy drop-in post    07:43
scuttlemonkey    but anything works :)    07:44
joelio    scuttlemonkey: sure have, talking about it at OpenNebulaConf in September, along with out use cases    07:44
scuttlemonkey    yeah, that's what made me think of it actually    07:44
scuttlemonkey    Jaime mentioned you were speaking    07:44
joelio    s/out/our    07:44
joelio    yea, wanted to drive some actual usage by users.. otherwise we'd be talking about a fairly sparse system. They are coming thick and fast now, users love it    07:45
scuttlemonkey    also didn't realize you were doing OpenNebula until recently    07:45
scuttlemonkey    I'll need to stand that up and become more familiar with it now that there are real live people using ceph+opennebula together    07:46
joelio    yea, I had to wait for about a month to get approval.. BBC beaurocracy.. <rolls eyes?    07:46
scuttlemonkey    haha    07:46
Vincent_Valentine    why are we writing multiple OSDs for a single write?    07:46
scuttlemonkey    big orgs same the world over    07:46
joelio    yup"    07:46
jyluke    I will be interested in opennebula+ceph as well, will be starting to do within the a few weeks time    07:46
Vincent_Valentine    If we write single OSD, the problem of logs factored over multiple OSDs will not be there.    07:46
joshd    Vincent_Valentine: replication is synchronous, writes go to the primary osd, which forwards them to other osds in the acting set and waits for all of them to apply the write before telling the client it's complete    07:47
Vincent_Valentine    Who is going to do erasure coding? Client or Another OSD?    07:49
Vincent_Valentine    If its another OSD, I can think of just replicating logs over 2/3 OSDs    07:52
rturk    ** Session "osd: cache pool overlay" starting in 5 minutes! || blueprint: || pad:    07:55
rturk    ** Please tell rturk or scuttlemonkey if you want to join the hangout    07:55
Vincent_Valentine    but it would simplify recovery ... am i wrong ?    07:55
rturk    sjust: ^    07:56
sjustlaptop    I'm not sure, can you expand on that?    07:56
*** jyluke has quit IRC    07:58
Vincent_Valentine    Im thinking on rolling forward for erasure coded tier. If logs are replicated, instead of fragmented by coding, recovery would be similar to replication PG    07:58
scuttlemonkey    sjustlaptop: ^^    07:59
Vincent_Valentine    1 more question ... How efficient would erasure coding would be for small object? And how does this translate to erasure coded RDB?    07:59
sjustlaptop    oh, logs will be replicated    08:00
sjustlaptop    rather than coded    08:00
sjustlaptop    the trouble is rolling forward the actual objects    08:00
sjustlaptop    the pg logs do not contain the full append data, for example    08:00
sagewk    Vincent_Valentine: can only roll forward if you have the M/N shards    08:00
sjustlaptop    (though perhaps they could)    08:00
sagewk    for replication, any 1 replica is enough    08:00
Vincent_Valentine    Understand that .. trying to simplify log consistency problem by detaching logs from erasure coding.    08:02

sagewk    Vincent_Valentine: see bottom of pad    08:04
Vincent_Valentine    sagewk .. what abt erasure coded RDB    08:05
*** ksp has joined #ceph-summit    08:05
Vincent_Valentine    so would there be tiers .. ? Is it planned in this release?    08:06
sjustlaptop    stay tuned!    08:06

rturk    ** Please tell rturk or scuttlemonkey if you want to join the hangout    08:06
Vincent_Valentine    :) .. i think its not same as caching ...    08:07
rturk    Vincent_Valentine: would you like to join the hangout?    08:07
*** dragonfly has quit IRC    08:07
rturk    might be easier than dealing with the live video feed delay    08:07
sjustlaptop    there are discusions for both tiering and caching    08:07
Vincent_Valentine    Heh ... m fine ... would like to participate in this though .. whom to contact ?    08:08
scuttlemonkey    loicd is the one driving erasure coding    08:08
scuttlemonkey    but for anything I would add yourself to the blueprint and start chatting with folks in irc and on the lists    08:09
*** davidzlap has quit IRC    08:09

rturk    ** Please tell rturk or scuttlemonkey if you want to join the hangout    08:13
Vincent_Valentine    Is cache pool replicated?    08:13
*** davidzlap has joined #ceph-summit    08:13
*** ksp has quit IRC    08:14
Vincent_Valentine    isnt that expensive for NAND ?    08:14
sjustlaptop    Vincent_Valentine: well, you could set replication to 1 (no replication)    08:15
sjustlaptop    but that would have an effect on durability    08:15
Vincent_Valentine    But then I loose all durability requirement ... cause we are modifying in cache pool    08:15
sjustlaptop    yes    08:16
sjustlaptop    could do write-through, I suppose    08:16
Vincent_Valentine    I was assuming write-through and no replication    08:16
sjustlaptop    would only accelerate reads    08:16
sjustlaptop    might be worthwhile though    08:16
Vincent_Valentine    To simplify this .. I would suggest two types of pools ... replicated for write-backs and unreplicated for unmodified data ...Question is who is managing write-back flushing? What policies? Who maintain write ordering?    08:18
sjustlaptop    Vincent_Valentine: as I understand it, the cache pool primary manages write ordering    08:19
*** mikedawson has quit IRC    08:19
joshd    there are no ordering guarantees with operations on different objects    08:19
Vincent_Valentine    aah ... then how does this work on RBD? 4MB objects with no ordering garuntee?    08:20
sjustlaptop    Vincent_Valentine: most disks don't give much in the way of ordering guarrantees either    08:20
joshd    all you can tell with most disks is 1 sector will be atomic (with rbd it's anything to a single object, and object boundaries will align with sectors in the virtual disk)    08:21
Vincent_Valentine    It was regarding eviction ordering for write-back cache. (especially RBD)    08:22

rturk    ** Please tell rturk or scuttlemonkey if you want to join the hangout    08:29
Vincent_Valentine    Just to be sure, we will promote whole object on caching pool? .... There would be case for doing small block(4KB) caching than object caching ...    08:29
*** sjustlaptop has quit IRC    08:34
scuttlemonkey    sagewk: just fyi, about 10m until objecter is slated, although we can probably eat into the break a bit    08:36

loicd    what parts of ceph use Objecter ?    08:56
sjustlaptop    loicd: clients    08:57
sjustlaptop    it's the ball of logic responsible for determining where to send client io    08:57
loicd    ohhhh    08:57
joshd    mainly librados, ceph-fuse, and the mds use it directly - other clients use librados    08:57

* wido was already listening in    10:05
wido    just missed the questions about the quota enforcement    10:05
wido    there is some serious lag in the video I think :)    10:06
scuttlemonkey    yes, the youtube link is maybe 2-3 mins behind the hangout    10:07
nwl    so it can be censored for bad language    10:07
scuttlemonkey    or wardrobe malfunctions :P    10:07
wido    Anyway, I don't think quota restriction has to be very tight    10:08
wido    a near perfect quota is fine for 99% of the situations    10:08
wido    maybe even 99.99%    10:08

sagewk    question for the room: who loves/hates gerrit?    10:38
scuttlemonkey    sagewk: having used it in the past, I really liked it    10:40
scuttlemonkey    was very approachable and (if done right) quite scalable    10:40
joshd    I strongly dislike gerrit - it only handles one commit at a time (encouraging unreviewable and too-large patches)    10:41
ircolle1    joshd - you can create a tree of patches    10:41
paravoid    wikimedia uses gerrit for pretty much everything    10:42
joshd    yes, but they're not reviewed or committed atomically    10:42
ircolle1    joshd - right    10:42
paravoid    I can provide some insight if you want    10:42

rturk    although the hangout is nearly full    10:43
paravoid    yeah, full    10:43

*** sjustlaptop has joined #ceph-summit    11:50
abluemle    Agree on the internal implementation via r*()    11:50
abluemle    IP is only relevant for connection establishment    11:51
sagewk    but do you need to know whether the peer is rsockets or does it fallb ack?    11:51
sagewk    i.e. can you use r* calls unconditionally and let magic happen?    11:51
abluemle    It does not fall back afaik    11:51
ksp    libSDP does use the fallback logic, and this fallback behavior can be added to rsockets as well    11:52
abluemle    libsdp is different concerning fall back: it does fall back to regular TCP sockets    11:52
abluemle    The IP address does not tell you about the rsocket character of the connection    11:54
abluemle    sth. like cluster network on rsockets and public network on regular sockets    11:56
ksp    The use case would be to run the cluster network with IB + rsockets and the client network still with Eth + IP-socket    11:56

sagewk    libdsp is EOL right?    11:58
dstroppa    rturk: can I have the link for the hangout for the cloud mgt platform?    11:58
ksp    yes, SDP is EOL    11:58
rturk    dstroppa: sent via pm, thanks :)    11:59
abluemle    For SDP there were userland and kernel parts    11:59
abluemle    option support is avaiable in rsocket    12:00
ksp    SDP has some license / legal risks ... this might be the reason for EOL    12:00
sagewk    what is option support?    12:00
ksp    sorry, didn't get the question    12:01
abluemle    setsockopt()    12:01
dmick    Did Matthew Anderson ever get anywhere, I wonder?    12:01
dalgaaf    Dieter: it's about "option support is avaiable in rsocket"    12:02

rturk    thanks, joelio!    12:26

joelio    yea, I'm liking it    12:27
scuttlemonkey    12:28
joelio    it sounds like the other management stacks have similar challenges, like lack of abstractions to handle types other than file, dev etc..    12:28

jyluke    thanks joelio    12:29
Tamil    rturk: oh ok thanks    12:30
joelio    not really, but there are subtle differences depending on your implementation. Most of the gotchas have been cought, the difficult ones to capture are distro and version nuances    12:30
joelio    (in terms of gotas I mean!)    12:30

joelio    there's definitely room for improvement in the model, currently just supports one pool. I've not tested multiple datastores of ceph type yet though, but I seem to recall there being some niggles    12:32

yehudasa    sagewk: you'll still want to have priorities, even as a single user, e.g., if you have tests running continuously and you want to get a single test running immediately    12:48
nhm    scuttlemonkey: close!    12:48
scuttlemonkey    hah    12:49
scuttlemonkey    I like mine better :P    12:49

nhm    Whatever we do with teuthology, the simpler the better.  I spend too much time right now trying to debug why something is broken. :(    12:51
alfredodeza    I would really like it to be a web service    12:52
alfredodeza    with an optional CLI that can talk to the HTTP API    12:52
alfredodeza    best of both worlds    12:53
alfredodeza    but, no ssh-keys, no '~/.teuthology' etc...    12:53

nhm    alfredodeza: I actually really like pdsh for this kind of thing    12:53
nhm    alfredodeza: I had a really really bad experience with folks that were very into semantic web interfaces and soured on the whole thing.    12:54
alfredodeza    better visibility, history of previous runs, see what machines are available/unavailable, etc...    12:54
*** leseb has quit IRC    12:54

alfredodeza    nhm: I see it as a couple of things: one is an API where you can interact with it (for tools like a CLI) and as a UI to interact with it through the web    12:55
alfredodeza    nhm: we should chat :)    12:56
nhm    alfredodeza: definitely has some advantages, especially if it can be done right.    12:56

loicd    :-)    12:59
alfredodeza    very nice    13:00
nhm    alfredodeza: was very much geared for low external dependencies and easy cluster creation.  With ceph-deploy a lot of this is probably obsolete or becoming obsolete.    13:00
alfredodeza    sure    13:00
alfredodeza    but the fact that this exists asserts we could totally leverage an HTTP service    13:00
