Hi, thanks for the clarification - but I still have the following question: - will we be able to take the already existing filesystem, created on a 32-bit node, use it on a 64-bit platform (i.e. upgrade all the nodes), and from there extend it to whatever size >16Tb we desire, or will we have to adjust blocksizes, etc. to go past the 32-bit platform limit? I understand that the filesystem itself, on-disk, is not the part imposing the limit - however I think I have seen somewhere that one has to use larger block sizes to reach the upper limits of file system size. Is this correct? Thanks again Jan -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
