Hello,
I would like to install ceph on a Netgear ReadyNAS 102.
It is a debian wheezy based.
I have tried to add ceph repository but nas is armel architecture and I
see you provide a repo for armhf architecture.
How can I solve this problem?
Thanks Loic

I usually like to go a little higher than 1GB per OSD personally. Given
what a box with 24 spinning disks costs, I'd be tempted to throw in 64G
of ram, but 32GB should do ok..

What has this have to do with ceph?
You can create a virtual machine with as many resources as a compute node has.
Since you can have unlimited virtual cores and also, using swap
space unlimited RAM, we could say yes to your question.
But if you are planning to use that machine for anything, I

Indeed. The benefit of having more memory is that the page cache can do
Hi.
I am trying to understand how much space available I will get on my Ceph
cluster if I will use three servers with 4x4Tb hard drives each.
Thank you very much!
Bye.

So 1GB RAM per OSD of Size 2TB(just re-iterating) is good enough?
Because I read somewhere 1GB RAM/OSD of Size 1TB is whats recommended
Well, 1GB is really the minimum. As Mark suggested, go for 64GB since
that probably isn't the most expensive

I all depends on the replication level you use, but let's assume 3.
So you get the capacity of one machine.
4 *
It is also useful to mention that you can set the noout flag when doing
maintenance of any given length needs to exceeds the 'mon osd down out
interval'.
$ ceph osd set noout
** no re-balancing will happen **
$ ceph osd unset noout
** normal re-balancing rules will resume **

I think my wording was a bit misleading in my last message. Instead of
no re-balancing will happen, I should have said that no OSDs will be
marked out of the cluster with the noout flag set.

Does replication level 3 mean that the data are all replicated three times
in the cluster?

4 * 1000 * 1000 / 1024 /1024 = 3.81TB
This would result in 15.24TB of raw space per

Replication is set on a per pool basis. You can set some, or all, pools
