Disk reservation feature update: more clusters and usable from the standard environment (sudo-g5k)

The disk reservation feature, which allows one to reserve on node local disks, is now available on more clusters:

• yeti in Grenoble
• chifflet, chifflot and chiclet in Lille
• parasilo in Rennes
• grimoire in Nancy

See the Disk reservation tutorial to understand how to take benefit from this feature.

Also please note that reserved disks are now also exploitable using sudo-g5k in the standard environment (does not require a deploy job).

New group storage service in beta testing, to replace storage5k

In order provide large, persistent and shareable storage among a group of user, we are introducing a new storage service.

This service is now available for beta testing at Lille: if you need to store large amounts of data in Grid'5000, we recommend that you try it!

See https://www.grid5000.fr/w/Group_Storage for details.

The service will be extended to some other sites after the beta testing phase.

This service aims at replacing storage5k, and existing storage5k services will be shutdown.

On Nancy and Luxembourg, the storage5k service will be retired on 2019-03-19, to free space in the server room for new machines. Other storage5k servers (on other sites) will be shutdown after the end of the beta phase of the new service.

If you are currently using Storage5k, your best options are:

• move data to your home directory (after requesting a disk quota extension if needed)
• move data to OSIRIM
• move data to the group storage service in Lille

See https://www.grid5000.fr/w/Storage for an overview of our storage options. (Note that we currently have two open issues with quota extensions and OSIRIM. If you submit a quota extension but do not receive a reply, or if you cannot access OSIRIM, please contact support-staff@lists.grid5000.fr)

Support of Jumbo frames now available

We are pleased to announce that all network equipments of Grid'5000 are now configured to support Jumbo frames (that is, large ethernet frames). We support an MTU (Maximum Transmission Unit) of 9000 bytes everywhere (including between Grid'5000 sites).

By default the reference and standard environments are still configured with a default MTU of 1500, but you can change the configuration (ip link set dev <device> mtu 9000) if needed. The same MTU value works from inside KaVLAN networks.
