Marco,
There are definitely folks who would love to see exactly what you are
asking for. However, it's not always as simple as it might seem.
With the ability to set replication levels per pool, and given that no
space is used until you write data to a given pool there are often too
many variable
Yes Bill,
but it would be nice to see the real space available reported at least
by the cephfs clients, retrieving the pool and the relative rep size
from the monitors and dividing accordingly the total space.
This could be a suggestion for Greg and the other guys working on the
first stable Cephf
Yes, that is the TOTAL amount in the cluster.
For example, if you have a replica size of '3' , 81489 GB available, and
you write 1 GB of data, then that data is written to the cluster 3 times,
so your total available will be 81486 GB. It definitely threw me off at
first, but seeing as you can hav
Hi,
I have a test cluster of 80Tb raw.
My pools are using rep size = 2, so the real storage capacity is 40Tb
but I see in pgmap a total of 80Tb available and also the cephfs
mounted on a client reports 80Tb available too
I would expect to see somewhere a "40Tb available"
Is this behavior correct?
Fantastic diagram, Wido, many thanks for doing this. Ross is in the
process of setting up a community wiki so hopefully we can host this
diagram there.

We had cephfs still mounted from earlier (before the copy pool, delete
pool). Basically, any file reads resulted in a I/O error, but
Dan,
this sound weird:
how can you run "cephfs /mnt/mycephfs set_layout 10" on a unmounted mountpoint?
My client says:
root@gw1:~# cephfs /mnt/ceph/ set_layout -p 3
Error setting layout: Inappropriate ioctl for device
And in IRC I've found that "path need to be a path to an already mounted cephfs"
We eventually resolved the problem by doing "ceph mds add_data_pool
10; cephfs /mnt/mycephfs set_layout 10", where 10 is the id of our new
"data" volume, and then rebooting the client machine (since the cephfs
mount was hung).
Cheers, Dan

Same here,
Now mounting cephfs hangs for a minute then says "mount error 5 =
Input/output error"
Since the new pool has id=3, I've also executed "ceph mds
add_data_pool 3" and "ceph mds remove_data_pool 0"
The monitor log has this line:

Hi,
In the last couple of months I got several questions from people who
asked how the Ceph integration with CloudStack works internally.
CloudStack is being developed rapidly lately and the documentation about
how it all works internally isn't always up to date.

I need to create the directory "/var/lib/ceph/mds/mds.$id "by hand, right ?
I start the service as you said, and it is succeed.
But, no "mds.$id" directory exist.
Will this affect it working?
And, what will be installed in the directory?
FS's metadata will be installed in OSDs, right?
Thanks.

I'm a new user of Ceph.
I have built a set up to try using RBDs, and it works brilliant.
I haven't enable MDS service, because I think I do not need it at that time.
But now, I want to try Ceph FS on the same cluster.
The question here is: I already have some data stored in RBDs.
