偶也来送分,先到先得(09):关于UFS文件系统的最大空间 [复制链接] |
|
10可用积分
最佳答案The UFS file system size is limited by the amount of space that can be addressed by the kernel buf structure. The buf.b_blkno structure field, defined as daddr_t, is a 32-bit signed value, and specifies the block/sector offset within a disk partition. The DEV_BSIZE, block or sector size, is 512 bytes. Therefore, a UFS file system could be as big as 1 TB (2^31 * 512).
