Ceph recovery network speed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I'm trying to understand why my recovery is so slow with only 2 pg
backfilling.  I'm only getting speeds of 3-4/MiB/s on a 10G network.  I
have tested the speed between machines with a few tools and all confirm 10G
speed.  I've tried changing various settings of priority and recovery sleep
hdd, but still the same. Is this a configuration issue or something else?

It's just a small cluster right now with 4 hosts, 11 osd's per.  Please let
me know if you need more information.

Thanks,
Curt
