Updating & Generating Overviews on Mosaic Dataset with 10 SP2

Hi, all,

With 10 SP2, we are facing one new issue, the lowest resolution level of overviews missing, when updating or creating overviews on larger Mosaic Dataset. 

In other word, if using the boundary of large Mosaic Dataset (containing 800-900 raster datasets) to define the extent of the mosaic dataset for overviews, saying 5 levels, the level 5 (lowest resolution of overview) should be visible at the extent of the mosaic dataset. But, with SP2, many lower levels of overviews are missing.

After examining, some lower levels (especially, level 5) do not cover whole extent of the mosaic dataset, i.e., only partially covering the region (see the snapshot 1).

With SP2, when some overviews missing or undefined, we usually choose the option to allow the application re-generating and re-building. Yes, we tried it several times in different ways so that this case is still reproduced under 64-bit Vista & 2008 SP2.

Is it reproducible in your workstations?  Missing anything?

In fact, this issue did not exist in ArcGIS 9.3.x, 10, and 10 SP1. Over there, the lowest level always covers whole extent completely. (See the snapshot 2 in 9.3.1 and snapshot 3 in 10 SP1).
