You mean "generate extend/reduce events that FS's smart enough to be able to deal with them (ie: *not* FFS or EXT2FS or ... but *maybe* NTFS depending on implementation, or JFS)"? Adding the events is the easy part. The FS's handling the events correctly in an FS specific way is harder. It's an FS problem, not a RAID/CCD problem that you want solved...
