What is the maximum file size/filesystem size?
• (REG) Maximum file size depends on the block size on your filesystem. For ext2 (and UFS, SysVFS and similar filesystems), the limits are: Block size Maximum file size (GiBytes) 512 B 2 1 kiB 16 2 kiB 128 4 kiB 1024 8 kiB 8192 (PAGE_SIZE must be >= 8 kiB) plus a small amount. The limitation is due to the classic triply-indirect addressing scheme. In the future, ext2 will have extent-based addressing, which will overcome this problem. The limit for a single filesystem (partition) on a 32 bit CPU is 4 Gi blocks. Each block is 512 Bytes, so that works out to 2 TiB. For 64 bit CPUs, the limits are bigger than you can imagine.
