This is usually caused by use of older kernel clients. I don't remember
exactly what version it was fixed in, but iirc we've seen the problem
with 3.14 and seen it go away with 3.18.
If your system is otherwise functioning well, this is not a critical
error -- it just means that the MDS
Hi All,
So this may have been asked but I’ve googled the crap out of this so maybe my
google-fu needs work. Does anyone have any experience running a Ceph cluster
with the Ceph daemons (mons/osds/rgw) running on the same hosts as other
services (so say Docker containers, or really anything
Which request generated this trace?
Is it nova-compute log?

All my server is ubuntu14.04 with 3.16 kernel.
Not all of clients appear this problem, the cluster seems functioning well
now.
As you say,i will change the mds_cache_size to 50 from 10 to take a
test, thanks again!

We run CEPH OSDs on the same hosts as QEMU/KVM with OpenStack. You need to
segregate the processes so the OSDs have their dedicated cores and memory,
other than that it works fine. Our MONs also run on the same hosts as the
OpenStack controller nodes (L3 agents and such) - no problem here, you
Hey,
I noticed today when trying to upgrade one of our clusters from Giant to
Hammer with ceph-deploy, but i ain't able to receive release.asc.
This happens because wget to ceph.com/git fails (seems to redirect to
git.ceph.com)
and then uses git.ceph.com that doesn't have IPv6 address at all.
In a similar direction, one could try using bcache on top of the actual
spinner. Have you tried that, too?
We haven't tried bcache/flashcache/...

Every HDD has a “mean access time” number (related to the rotation speed,
number of heads, etc.)
with 8ms access time this gives you 1000/8 = 125 seeks per second.
This is where it comes from :-)

For very small values of production. I never had more than a couple clients
hitting either of them, but they were doing real work. Ultimately though,
we decided to just use NFS exports from a VM to do what we were trying to
do with rgw and mds.
