Hi, It seems that max-stripe-waste parameter of COSS file system isn't implemented And actually it's equale to max-stripe-waste=1M cs->sizerange_min isn't used and storeCossAllocate function doesn't put a limit. Actually, it leads to COSS disk space waste, when an object larger then free space comes current stripe will be writen as is even if there is large unused part. Is there any reason why this isn't implemented ? or it should be consider as a bug Thanks Itzcak
