Re: [ceph-users] Bad performance when two fio write to the same image

If you search through the archives, there's been a couple of other people that have run into this as well with Jewel. With the librbd engine, you are much better using iodepth and/or multiple fio processes vs numjobs. Even pre-jewel, there were gotchas that might not be immediately apparent.

Wow, thanks. I think that¹s the tidbit of info I needed to explain why increasing numjobs doesn¹t (anymore) scale performance as expected. Warren Wang On 8/4/16, 7:49 AM, "ceph-users on behalf of Jason Dillaman" wrote: >With

Re: [ceph-users] fast-diff map is always invalid

Can you run "rbd info vm-208-disk-2@initial.20160729-220225"? You most likely need to rebuild the object map for that specific snapshot via "rbd object-map rebuild vm-208-disk-2@initial.20160729-220225". On Sat, Jul 30, 2016 at 7:17 AM, Christoph Adomeit wrote: >

If you are attempting to use RBD "fancy" striping (e.g. stripe unit != object size and stripe count != 1) with krbd, the answer is that it is still unsupported. On Wed, Aug 3, 2016 at 8:41 AM, w...@globe.de wrote: > Hi List, > i am using Ceph Infernalis and Ubuntu 14.04 Kernel

If the client is no longer running the watch should expire within 30 seconds. If you are still experiencing this issue, you can blacklist the mystery client via "ceph osd blacklist add". On Wed, Aug 3, 2016 at 6:06 PM, K.C. Wong wrote: > I'm having a hard time removing an RBD

Re: [ceph-users] Bad performance when two fio write to the same image

With exclusive-lock, only a single client can have write access to the image at a time. Therefore, if you are using multiple fio processes against the same image, they will be passing the lock back and forth between each other and you can expect bad performance. If you have a use-case where you
