DHEthere's probably an existing replication job that's busy15:07
*** gyee has joined #openstack-swift15:13
viks____DHE: thnx... but what is this `LockTimeout (10s)`...15:16
DHEreplication locks various things, and especially replication may hold it locked for an extended period15:18
viks____from where it is getting this 10s value from? i do not have any 10 seconds value set in my container-server.conf15:19
DHEthat's just how long it will wait on a lock15:20
viks____can i increase it ... i mean Locktimeout value?15:37
*** hoonetorg has joined #openstack-swift16:01
DHEI wouldn't bother most of the time. the lock is probably being held by a different cluster member trying to do the same sorts of things that this server wants to do16:20

claygis there a swift meeting today?20:45
timburkeyes please!20:45
claygviks____: that 10s lock timeout means you have a lot of contention on your container disks 😬20:46
claygviks____: time for some sharding!!! or SSDs if you're not there already20:46
claygof if you're using the same spindles for dbs and objs that's the worst - I'm not saying some swift deployments shouldn't be able to do that...20:47
claygviks____: ... but with your access patterns that's not going to work for you for much longer - that's what that error is telling you20:47
claygor rly, I guess that error wasn't really being helpful at all 😞20:47
claygsoftware is terrible, but on the clusters where I've seen that error before the story is "you've run out of iops on your container disks" - so... you have to go from there!20:48
claygI mean you could check me with iostat - look at your await in particular20:49
claygthose sqlite index updates can be bear 💪20:49
