thomaschaafhello I have the following devices: http://pastebin.com/8FbXFSCy the weight is the size of the device. My problem is that device #7 is full and is causing lots reads: https://dl.dropboxusercontent.com/u/5910/Jing/2015-01-04_1639.png what should I do if I can't add drive space?15:44
ctennisthomaschaaf: you should rebalance the ring again, it will redistribute the partitions more and replication will move things around15:48
thomaschaafhavent rebalanced in a while..15:49
ctennisdevice 7 has 75321 partitions assigned to it, while device 6 only has 2603615:49
thomaschaafgetting an error15:49
ctennisa rebalance should bring #7 more in line15:50
thomaschaafdevice 6 is in another zone though15:50
thomaschaaf*in another region15:50
ctennisah I missed that15:50
thomaschaafhttp://pastebin.com/SADMHMEC15:50
ctenniswhat version of swift?15:51
ctennisI haven't run into that error before15:53
thomaschaafswift-ring-builder 1.315:58
thomaschaafwhich is 2.2.0 I think15:59
thomaschaaflet me check15:59
thomaschaaf2.2.0-0ubuntu115:59

ctennissomeone else might weigh in here, probably worth opening a ticket on launchpad though16:12
ctennisbut in general, your out of balance situation seems to be the likely culprit..you might check and see how many partitions you actually have on that device as well.  In some cases I've seen where you can get erroneous partitions that should be cleaned up, but aren't because replication is either way behind, or can't move them off due to other disk space issues.16:13
ctennisalso keep in mind that the balancing algorithm is not all that well behaved for when you have multiple zones/regions that are not similar sized16:13

lcurtiswonder if anyone might be able to briefly explain how i would reference multiple controller nodes?17:19
lcurtiswithout a load balancer17:19
lcurtisusing dns RR....would i just create a keystone endpoint http://dnshostname.xxx and then enter all proxy ips in dns?17:20
*** Masahiro has joined #openstack-swift17:22
*** Masahiro has quit IRC17:27
ctennislcurtis: yes that would work17:29
lcurtisthank you ctennis!17:29
ctennislcurtis: you just need some mechanism for removing the IPs if your proxy is down17:30
lcurtisi am trying to do as much in parallel on regular 1gb switches17:30
ctennisor your clients will spend time waiting for timeouts if they can't reach it17:30
lcurtismy 10gb switches have not arrived yet....which i will use as eventual front end with haproxy17:30
lcurtisso will use bindmon in the meantime17:31
lcurtishttp://hitachi-id.com/dlsoftware/bindmon/17:31
lcurtishoping it works, but might be able to script around it if not17:31

thomaschaafI would love to see "last access" stats for files has anyone created something to track this? Or how else would I get this info?18:17
thomaschaafI would like to delete files in a container which haven't been used in a long while (am using swift as image thumbnail cache)18:17
