Please correct the table or the code, your choice. Let me quote from http://www.suse.de/~aj/linux_lfs.html > * On 32-bit systems with Kernel 2.4.x: The size of a file and a block device is limited to 2 TiB. By using LVM several block devices can be combined enabling the handling of larger file systems. > * 64-bit systems: The sizes of a filesytem and of a file are limited by 2^63 (8 EiB). But there might be hardware driver limits that do not allow to access such large devices. > * Kernel 2.6: For both 32-bit systems with option CONFIG_LBD set and for 64-bit systems: The size of a file system is limited to 2^73 (far too much for today). On 32-bit systems the size of a file is limited to 2 TiB. Note that not all filesystems and hardware drivers might handle such large filesystems. Since you mention a 16 TiB file size limit on 32 bit, I have to assume that either the 2 TiB file size limit on 32bit is no more or your page is incorrect regarding this limit. And what I'm especially interested in: What are the limits of Reiser4? I couldn't find any information about it (maybe I didn't search long enough). Regards, Carl-Daniel -- http://www.hailfinger.org/
