The L-store team is hesitant to call it 1.0 because there's no fault tolerance on the metadata yet 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. The team feels that those features are essential for a 1.0 release.

He has even/odd coding working with the NFU under L-Store.
			*Terry raised the question of how were going to get LoRS-view like functionality for L-Store. This is essential for various presentations that we need to make this fall, beginning Sept. 17. It was suggested that we get a student to work on this in September. Terry has concerns about whether we're working hard but not working smart, i.e. whether this plan accords this task the right priority or will be soon enough.
	~~What’s~~ the ~~status on~~ LoRS view~~? The plan~~ is to ~~assign~~ a student ~~intern~~ to it.		*Micah talked about his recent email about our approach/theory about content control on the depots in relation to the Digital Millennium Copyright Act (DMCA)

			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.

			Various possible sources of the problem were discussed.

			It’s not reproducible yet.
