Nagio page

2 depots are being sent to PR; that would be 6TB; if we need more we can add to that.

In working with the Library of Congress, ACCRE has discovered a bug and he doesn’t know where it sits. Some allocations on resource 0 are disappearing. The standard way IBP has been used is to configure separate disks as separate depots, rather than as one depot with 4 resources. Under the latter configuration, it’s breaking, losing slices. It seems to be some kind of confluence of factors, which may include.

Various possible sources of the problem were discussed.

It’s not reproducible yet.

Working with VTNA

External sites where we’re going to install sights 1) UM 6TB 2. Cal Tech 6TB 3. Florida 6TB

Tyan motherboard and chasis. Nothing. Using 3TB per U 4 750GB drives 3 or 4 at UMich $2045 per TB, $700 per TB 3TB per depot

SDSC – Terry and Micah will grease the wheels here. ORNL is another option.

(2) Alan/Larry/Hunter: status of L-Store work at ACCRE/Nevoa

    a) LoRS/L-Store view

Santi got a new version of Nevoa explorer; Storecore is working and fully integrated with L-Store; Storecore is providing the depot list,

L-Store is scheduled to do a release; There are issues with the GUI that Santi is working with. Discussed L-Store with Brian Burke and he has even/odd code working Aislan: We tested the L-Store client with N-explorer and store core at there site. They discovered some problems and fixed them.

They have a java installer for Nevoa explorer. They plan to make and installer for L-Store.

L-Store will be release .8. There’s no fault tolerance on the Metadata and the security features haven’t been activated. The security feature doesn’t scale at this point and there’s no user interface for it.

What’s the status on LoRS view? The plan is to assign a student intern to it.

    b) Nevoa integration
    c) packaging for install
    d) testing status

They’re doing nightly builds

Micah talked about his recent missive on DCMA and content control on the depots.
