onovybut this is correct workaround i think12:23

admin6Hi team, I’m running Swift on 4 ACO servers (installed with Ubuntu 16.04.2 LTS) and swift v2.7.1-0ubuntu1. I’ve recently added a fifth server, which is running with the latest updated version of ubuntu : Ubuntu 16.04.3 LTS and swift  2.7.1-0ubuntu2 (I know it’s an old swift version but it’s the official long term support ubuntu version of swift :-/  )16:19

admin6The (need to be reconstructed) fragment is actually missing on the related disk. Have you already seen this type of error ?16:21
*** OrionX has joined #openstack-swift16:23
timburkeadmin6: so that's one side of the connection -- are there errors being logged on the other side? probably something involving swift/obj/ssync_sender.py16:24
timburkeit rather sounds like the sender just hung up without sending everything. the receiver won't write anything down unless it's fairly certain that it has a complete, correct fragment16:25

openstackLaunchpad bug 1730511 in OpenStack Object Storage (swift) "SWIFT API: Cannot pull container information across all accounts in one call" [Wishlist,New] https://launchpad.net/bugs/173051123:29
claygafaict next step would be an ideas write up23:29
clayg... we've at somepoint realized that a given what we know about our largest swift deployments one *could* have a single sqlite database with "all" the account names listed in it... and we could probably get away with a process like the the container-updater (account-updater?) to keep it up-to-date?23:30
clayg... but you know ... we could also just keep doing our thing with slogging clones or using the auth system for account enumeration or whatever we've already solved this need with...23:31
claygbut ... new people keep having to solve it ... oh well!23:31
