This metadata is stored at the + start of the device so is safer in many ways but could interfere with + boot loaded. The old default (0.90) is still available and fully + supported. + + - The default chunksize is now 512K rather than 64K. This seems more + appropriate for modern devices. + + - The default bitmap chunksize for internal bitmaps is now at least + 64Meg as fine grained bitmaps tend to impact performance more for + little extra gain. + +This release is believed to be stable and you should feel free to +upgrade to 3.1.1. + +NeilBrown 19th November 2009 -- cgit
