You can create multiple COSS stores for a disk but I've found the IO performance degrades quite noticeably with this. * I'm having a few spots of trouble using the large file offset support in Linux but I'm sure I'll fix it. I'm working on it but I have lots of work on my plate; I'll try to get it done as soon as I can. Adrian
