Is the "upstream" Storage Server fully open source, or are parts of it
closed source?
Are the RPMs to build one already in the Centos repo? If not, are there
any plans to offer them?
I am looking for something free to use in Haiti, that will offer redundant
file storage and automatic failover to a second set of hardware in case of
a failure of the primary hardware.
If RHSS is not available or suitable, other suggestions welcome. I need a
file system/server with:
* primary function is serving MP3 files for playback in a radio station
environment in Haiti
* if the system goes down all your clients (listeners) know it
* they know it NOW
* they know how long it takes to get it back up
* High Availability as the primary concern
* ability to administrate via web interface or similar by non-Linux-savvy
IT staff.
* ability to grow file system from 2-3TB to 20-50TB by simply adding disks
and/or adding 'bricks'
* clients will all be Windows computers, so files accessible by CIFS
* critical application is read-only
* prefer a system that would continue serving files even if the network
goes down (but have not found such a system yet for Windows clients). This
would require something like Ceph with a full (non-server) windows client,
so the local node would continue to function until the network came back up.
* throughput is not a large issue

You can install it from http://repos.fedorapeople.org/repos/kkeithle/glusterfs/epel-6/ A relatively recent guide here: http://www.gluster.org/wp-content/uploads/2012/05/Gluster_File_System-3.3.0-Administration_Guide-en-US.pdf I recommend you get on their mailing list and IRC channel. http://www.gluster.org/interact/ -- Sent from the Delta quadrant using Borg technology!

Distributed failure-tolerant systems are a lot easier if you don't even try to provide filesystem semantics that require a lot of atomic operations. -- Les Mikesell lesmikesell at gmail.com

From Fedora (https://fedoraproject.org/wiki/Staying_close_to_upstream_projects): In general, when Centos folks refer to upstream in general terms, they are talking about RedHat. It often seems to be used in order to avoid too much use of the Trademarked name that makes Centos possible. If someone is talking about a specific program (say apache or MySQL) and they refer to upstream, they are probably referring to the developers of that specific program. Ted Miller P.S.
