mattoliveraumahatic: https://etherpad.openstack.org/p/1lt3r3Si17 The diff I placed at the end of the etherpad seemed to work for me.06:10
mahaticmattoliverau, oh taking a look06:10
mahaticmattoliverau, to test it, i'm only doing a "resetswift" and then "startmain". And then testing. Am i going wrong there?06:12
mattoliveraumahatic: swift client doesn't affect the swift cluster. So you don't have to resetswift. I just made the changes to python-swiftclient and you used 'python setup.py develop' on the swift client code it should load the changes automatically06:15
mahaticmattoliverau, oh alright. Thanks so much!06:16
mahaticmattoliverau, maybe that is why it was not loading the changes for me. Sorry, my bad.06:16
mattoliveraumahatic: lol, thats how you learn :)06:17
mahaticmattoliverau, :)06:18
mahaticmattoliverau, thank you. I have tested it. Will send the patch soon06:30

ttrummHello how much swift connections to port 6000 is normal? I have 40k+08:17
ahaleis your cluster busy? 6000 is the object server port so .. proxies getting/writing objects, replicators.. pretty normal to have a lot of 6000, 6001, 6002 in a swift cluster since those are the default daemon ports08:19
ttrummyes but conntrack table getting full, i doubled net.ipv4.netfilter.ip_conntrack_max and set /proc/sys/net/ipv4/ip_local_port_range to 1024 6500008:26
ahaleoh yeah we run our stuff without conntrack cos its a real pain, monitoring socket counts as well stuff like that .. its relatively normal though .. just got to scale before it comes a problem08:36

mahatickbee,  "E111 indentation is not a multiple of four" I get that error11:44
mahatickbee, would you happen to know if there is a rule on how try except blocks should be indented? I have put it right above if block11:46
kbeemahatic: that implies, that the indentation has gone bad. it has to be 4x. I would strongly recommend you to go through http://legacy.python.org/dev/peps/pep-0008/ and http://docs.openstack.org/developer/hacking/ atleast couple of times..11:47
kbeemahatic: following that would resolve this. Also, you need to add some unit tests to accomodate your changes.. else once you correct ur pep8 error, unit tests would fail.11:48
mahatickbee, oh sure. okay. i'm working on python-swiftclient. How to go about unit tests?11:49

swift_fan1ctennis -- Right, I know what handoff nodes/devices are, but what exactly is a 'handoff partition' ?18:45
swift_fan1Does swift really deal with handoff nodes/devices on the disk-partition level?18:46
swift_fan1I'm confused.18:46
*** CaioBrentano1 is now known as CaioBrentano18:46
notmynameswift_fan1: no. swift's partitions don't have anything to do with filesystem partitions18:47
swift_fan1I understand completely what the idea of a handoff is,18:47
*** kopparam has quit IRC18:47
*** mahatic_ has joined #openstack-swift18:48
swift_fan1but not sure about the logic that is going on when handoffs are done on the 'partition' level .....18:48
swift_fan1So 'handoff partition' is on the swift-partition level, or the filesystem-partition level ?18:48
zaitcevA partition in Swift partitions the address space.18:49
zaitcevAddressed by hash.18:49
*** nitika1 has quit IRC18:51
swift_fan1So what's the difference between 'handoff node' and 'handoff partition' ?18:52
swift_fan1And is 'handoff' used as the same concept, in both places?18:52

dmsimardHave a weird issue.. object-auditor going crazy looping endlessly really fast "Begin object audit "forever" mode".21:17
dmsimardOn just one storage node on a barely empty cluster.. stopping/starting does not help, debug logs do not provide much details21:18
dmsimardAny other clues where I could start ?21:23
dmsimardhuh. Looks like it eventually stopped by itself.21:24
dmsimardNevermind that, it's back :D21:24
NM1dmsimard: Any idea what happened?21:26
*** ZBhatti has quit IRC21:26
dmsimardNo clue.. it's an unused (as of yet) cluster. 10GB used out of 400TB across 6 storage nodes.. It's the only node out of the 6 with that issue.21:28
dmsimardMount points and drives are there, was looking at launchpad if there was any bugs that could explain the behavior21:28
dmsimardThere are no errors or stack traces, that's for sure21:28

NM1dmsimard:  What does "os02-z3" means and which log_level are you using?21:34
dmsimardNM1: That's the hostname of the machine. I turned on debug and didn't see anything else that was helpful. The lines in that paste are INFO, though.21:34
dmsimardobject-auditor doesn't log anything else than the above in debug21:35
NM1Hummm.21:37
NM1Are All of your disks mounted and readable? If you run $ df -h, does it finishes successful   ?21:38
*** rmcall has joined #openstack-swift21:39
dmsimardNM1: Yup. Nothing in dmesg or syslog either.21:39
dmsimardI just tried rebooting the node, see what happens21:39
zaitcevwell there's https://review.openstack.org/125197 - not necessarily dmsimard's problem exactly, but auditor can go weird like that21:49
zaitcevI saw auditor disobey interval before, but have reproducible21:49
zaitcevs/but have/but never/21:50
dmsimardI might have found the issue, looks related to DNS resolutionç21:51

zaitcevoh wow21:55
zaitcevLeft undiscovered is why in the world an auditor would want DNS.21:55
NM1zaitcev: Reverse DNS?21:56
zaitcevyeah, why? An auditor is purely a local process.21:56
*** tsg has joined #openstack-swift21:56
zaitcevwell, it might need DNS for things like logging if you use hostname for that... but that's a little far-fetched.21:57
zaitcevstatsd maybe21:57
NM1We could strace the process but I think it would be easier to look at the source code.21:59
dmsimardNope, there was a DNS issue that I fixed but the issue remains22:02
zaitcevdmsimard: how many processes can you see if you do something like  ps auxw| grep object-auditor| wc -l  and does that number match your configuration?22:04
dmsimardzaitcev: Two object-auditors22:05
zaitcevdmsimard: good, that's correct - one ZBF and one normal... I need to look at the code and think why it could be looping22:06
zaitcevlike your NTP broke or something22:06
zaitcevdmsimard: could you throw your object-server.conf to http://paste.openstack.org, just for surety?22:07
dmsimardzaitcev: http://paste.openstack.org/show/XIZUmfdSOp0OcQt9pZCy/22:08
dmsimardzaitcev: Date and NTP looks fine22:08
zaitcevsorry, it was a wild guess22:08
dmsimardzaitcev: Could've been a good one :)22:09
zaitcevWhat do you think about stracing it like NM1 suggested?22:09
dmsimardDidn't see that, can try, hang on22:09

dmsimardzaitcev: Bug worthy you think ?22:27
swift_fan1NM1 notmyname : And whether the 'partition' in the term 'handoff partition' is referring to a Swift partition, or to a filesystem partition.22:27
