ADITI is the preview grid for Second Life. This is where we test new scripts, mesh items, and lots of other stuff. It is popular with creators because uploads are free. Currently people are having problems logging in. The problem is caused by the hard drives for the ADITI database filling up.
There will be discussion at Thursday’s Beta Server meeting on what may be the best solution for the problem. If you use the preview grid, you will probably want to be there for that meeting.
Discussion in the SL Forum: ADITI Problems Thursday Meeting
ADITI is smaller than the main grid and runs on less hardware. The database for assets on the ADITI is much smaller, hardware-wise. Oskar Linden, no longer on staff, was handling keeping the grid running. But, the situation required manual cleaning of the drives. Now that is proving a problem.
How the problem is going to be resolved is up for discussion at Thursday’s 3:00 PM Beta Server user group meeting. See: Server Beta User Group. I suggest you attempt to log into ADITI at least by Wednesday. You may find you can only get in with an Alt-avatar.
When a disk fills up there is a finite number of solutions. While adding a larger drive seems like a simple solution, SL does not run on ‘a drive’. It uses a cluster of computers with large drives. Cost is a factor. As Simon Linden says these are not drives you can pick up at Fry’s. So, some alternative is being looked at.
The primary one is looking at how to cull out people not using the ADITI grid. Their inventory does not need to be on the preview grid. Next is the idea of flushing the inventory of anyone not using the preview grid for some time period.
Most of the solutions are going to involve reducing the number of people with inventory on ADITI. I think it is reasonable to expect that if you are an infrequent user, your inventory will get flushed from time to time.
Also, if you are someone with a HUGE inventory, it is reasonable for that flush period to be shorter. I think some incentive for you to keep inventory small on the ADITI grid is needed. While it would take some extra effort to use an alternate with a small inventory, I don’t see it as that big a deal.
I think limiting inventory to those regularly using the grid and timing out infrequent users will be the likely solution. But, if you have a stake in this decision, show up and participate.
In discussing this problem information came out about how the asset system works. All the assets are not in a database. The assets are files on a disk. The asset system uses a database to index the location of the asset’s files. This makes the database way smaller.
An interesting trivia point is the asset files for both AGNI and ADITI are kept in the same filing system cluster. The databases with pointers into the system for ADITI and AGNI are separate databases.
Andrew is looking into how the ADITI grid works and what solutions may be best. I expect we may learn more about how the system works at Thursday’s meeting.
