Hello All,
I went through the below link and checked that Copy-on-Read is currently
supported only on librbd and not on rbd kernel module.

Can someone please let me know how to test Copy-on-Read u
One interesting use case of combining Ceph with computing is running big
data jobs on ceph itself. As with CephFS coming along, you can run
Haddop/Spark jobs directly on ceph without needed to move your data to
compute resources with data locality support. I am wondering if anyone
in community is l

It's not directly solve the data locality problem but try to avoid

Hi,
I am planning to modify our deployment script so that it can create and deploy
multiple OSDs in parallel to the same host as well as on different hosts.
Just wanted to check if there is any problem to run say 'ceph-deploy osd
create' etc. in parallel while deploying cluster.
Thanks & Regards
The systemd service unit files were imported into the tree, but they
have not been added into any upstream packaging yet. See the discussion
at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=769593 or "git log
-- systemd". I don't think there are any upstream tickets in Redmine for
this yet.

I will take a look into the perf counters.
Thanks for the pointers!

Hi,
I'm benchmarking my small cluster with HDDs vs HDDs with SSD Journaling. I am
using both RADOS bench and Block device (using fio) for testing.
I am seeing significant Write performance improvements, as expected. I am
however seeing the Reads coming out a bit slower on the SSD Journaling side.

Hi!
I mistakenly created my MDS node on the 'wrong' server a few months
back. Now I realized I placed it on a machine lacking IPMI and would like
to move it to another node in my cluster.
Is it possible to non-destructively move an MDS ?
Thanks!

I've been working at this peering problem all day. I've done a lot of
testing at the network layer and I just don't believe that we have a

I have this ceph node that will correctly recover into my ceph pool and
performance looks to be normal for the rbd clients. However after a few minutes
once finishing recovery the rbd clients begin to fall over and cannot write
data to the pool.
I've been trying to figure this out for weeks! N
