[Lustre-discuss] What do you think of this idea?

[David Noriega]

The idea is to have an extra place to backup our file server. To run
incremental backups on the weekends. Have a script to check if the
workstations are online first. Eventually the main fileserver will be
Lustre, but this would be a duplicate of the fileserver. So our services
would not be depending on this.

As it stands, the machines are hardly used, and a modified kernel is fine.
On the occasion they are used, students tend to just check email, maybe
matlab, but more often then not when using matlab its remotely off of a
compute server.

Or would it be better to use some other filesystem. What about what comes
with Redhat/CentOS in their cluster packages?

Personally, I liked the university. They gave us money and facilities, we
didn't have to produce anything! You've never been out of college! You don't
know what it's like out there! I've worked in the private sector. They
expect results. -Ray Ghostbusters
