Hello All,
I have a simple test setup with 2 osd servers each 3 NICs (1Gb each):
* One for management (ssh and such)
* One for the public network (connected to ceph clients)
* One for the cluster (osd inter-connection)
I keep seeing this messages:

Hello all,
Our dev environment are quite I/O intensive but didn't require much
space (~20G per dev environment), for the moment our dev machines are
served by VMWare and the storage is done in NFS appliances with SAS or
SATA drives.
After some testing with consumer grade SSD we discovered that

Hello,
Is this a good idea to run the osd and nova compute on the same node or
not so much and if so why ?

Hi,
I have a couple of HW provisioning questions in regards to SSD for OSD
Journals.
I’d like to provision 12 OSDs per a node and there are enough CPU
clocks and Memory.
Each OSD is allocated one 3TB HDD for OSD data – these 12 * 3TB HDDs

Hi list,
I'm trying to create a active/active Samba cluster on top of Cephfs
I would ask if Ceph fully supports CTDB at this time.
If I'm not wrong Ceph (even CephFS) do not support exporting a block

Hi,
I was doing some testing with iozone and found that performance of an
exported rdb volume where 1/3 of the performance of the hard drives.
I was expecting to have a performance penalty but not so important.
I suspect something is not correct in the configuration but I can't what
exactly.
Anyone on this one ?
