Hello,
Just a general question really. What is the recommended node size for Ceph
with storage clusters? The Ceph documentation does say use more smaller
nodes rather than fewer large nodes but what constitutes to large in terms
of Ceph? Is it 16 OSD or more like 32 OSD?
Where does Ceph tail off
I agree, I have tried it before and even with tmpfs and removing the
logs, usb sticks will last only a few months (3-4 at most)

Hi, everyone!
I have installed ceph RGW, but didn't know sucessful or not.
I first installed ceph in 3 servers and installed MDS. I could upload files
by mount a disk to ceph.
Then I installed RGW in this ceph.
Server OS: CentOS 6.4 x86_64
When I started radosgw, It showed:

Hi All,

Not all USB sticks are the same. Some will last much much longer than others
before they become write-only.
Is anyone making USB memory sticks built on the sa
Hi,
Has anyone written a book, ebook, etc about CEPH, including from
basics to performance tuning?
Thanks,

Ceph is seriously badass, but my requirements are to create a cluster in which
I can host my customer's data in separate areas which are independently
encrypted, with passphrases which we as cloud admins do not have access to.

Hi guys,
I need to add a extend server, which reside several osds, to a running
ceph cluster. During add osds, ceph would not automatically modify the
ceph.conf. So I manually modify the ceph.conf
And restart the whole ceph cluster with command: 'service ceph -a restart'. I
just confuse
Why not have the application encrypt the data or at the compute server's file
system? That way you don't have to manage keys.
