Hi Everyone,
I'm looking for some SSD's for our cluster and I came across these Samsung DC
SV843 SSD's and noticed in the mailing lists from awhile back some people were
talking about them.
Just wondering if anyone ended up using them and how they are going?
Thanks in advance,

and leverage some nice SSD's maybe a P3700
400GB
for the zil/l2arc with compression and going back to 2x replicas which then
this could give us some pretty fast/safe/efficient storage.
Now to find that money tree.

procedure everything was ok and the osd.0 had been
emptied and seemingly rebalanced.
Any ideas why its rebalancing again?

Hi Christian
x replication it's a pretty good
cost saving however 3x replication not so much.

As you may know increasing the concurrent io's will increase cpu/disk load.

Ie: 50 OSD System with 3 replicas would be around 1600
Hope this helps a little,

mostly work be it FreeNAS iSCSI can get a bit cranky at times.
We are moving towards another KVM Hypervisor such as proxmox for these vm's
which don't quite fit into our Openstack environment instead of having to use

If this is the case Is it possible to calculate how many IOPS a journal would
absorb and how this would translate to x IOPS on spindle disk?

Hi Sage, Andrija List
I have seen the tuneables issue on our cluster when I upgraded to firefly.
I ended up going back to legacy settings after about an hour as my cluster is

data, which after an hour all of our
Hi All,
Just a quick question for the list, has anyone seen a significant increase in
ram usage since firefly? I upgraded from 0.72.2 to 80.3 now all of my Ceph
servers are using about double the ram they used to.
Only other significant change to our setup was a upgrade to Kernel

Does Radosgw support a Public URL For static content?
Being that I wish to share a File publicly but not give out

Hi All,
I'm finding my write performance is less than I would have expected. After
spending some considerable amount of time testing several different
configurations I can never seems to break over ~360mb/s write even when using
tmpfs for journaling.
So I've purchased 3x Dell R515's with 1 x
