Hello
got several OSD's that are crashing. Migrated last week from Ubuntu 14.10
(don't know CEPH version) to 14.04 and since then several OSD's are flapping.
Here a log file from one of the OSD that is flapping. Would appreciate any help
in getting back a stable CEPH cluster.
There are 3 Nodes
when I create bucket, why rgw create 2 objects in the domain root pool.
and one object store struct RGWBucketInfo and the other object store struct
RGWBucketEntryPoint
and when I delete the bucket , why rgw only delete one object.

simple messenger is the classic messenger protocol used since the begining of
ceph.
xio messenger is for rdma (infiniband or Roce over ethernet)
they are also a new async messenger.
They should help to reduce latencies (and also

Again, penultimately you will need to sit down, compile and compare the
numbers.
Start with this:

Pay close attention to the 3610 SSDs, while slightly more expensive they
offer 10 times the endurance.
Guestimate the amount of data wri

Now, I've never setup a journal on a separate disk, I assume you have 4
partitions at 10GB / partition, I noticed in the docs they referred to 10
GB, as a good starter. Would it be better to have 4 partitions @ 10g ea or
4 @20?

I am not sure about the enterprise grade and underprovisioning, but for the
Intel 520s i've got 240gbs (the speeds of 240 is a bit better than 120s). and
i've left 50% underprovisioned. I've got 10GB for journals and I am using 4
osds per ssd.

Ok, any size suggestion? Can I get a 120 and be ok? I see I can get
DCS3500 120GB for within $120/drive so it's possible to get 6 of them...

I am trying to get Ceph running on an openSUSE 13.2 cluster, but it seems that
I cannot generate the keys since ceph-create-keys hangs. I have tried with
Giant and Firefly and I am getting the same results on both. It works just fine
on openSUSE 13.1.

I would not use a single ssd for 5 osds. I would recommend the 3-4 osds max per
ssd or you will get the bottleneck on the ssd side.
I've had a reasonable experience with Intel 520 ssds (which are not produced
anymore). I've found Samsung 840 Pro to be horrible!
Otherwise, it seems that everyo
Well, although I have 7 now per node, you make a good point and I'm in a
position where I can either increase to 8 and split 4/4 and have 2 ssds, or
reduce to 5 and use a single osd per node (the system is not in production
yet).
Do all the DC lines have caps in them or just the DC s line?

Don't know if this email got delivered some days ago. It may seem not.
Re-sending it again hope someone can add something :)
Thank you,

Hi Christian,
I didn't create the partitions beforehand, which is probably the reason why we
had differing outcomes.
The actual partitions were fine, I could mount the root partition from a live
cd. However when the server tried to boot it never loaded grub, it just sat
there with a blinking c
