linux - What is the maximum file size and filesystem size in a 32 bit system -


  Question: What is the largest size of the files on the ext3 file system and ext3? Ext3 files can support up to 1TB The size of the file system with 2.4 kernel is limited by the maximum block device size, which is 2TB. Max 2.6 (32-bit CPU) border block device is 16TB, but ext3 only supports up to 4TB  

I read that the size of the area holding a maximum file Inod structure The size is determined by the variable. So on a 32 bit system it is 2 ^ 32 4294967296 which is 4 * 1024 * 1024 * 1024 => 4 GB. Does the 32-bit system have the maximum file size of 4 GB?

The size of the file system can be calculated with the size of a block size of the inode blocks *. 12 + 1024 + 1024 * 1024 + 1024 * 1024 * 1024 => 12 + 1024 + 1048576 + 1073741824 => 1074791436 No. of ions.

FS Size = Any ions * Block Size = 1 TB

Is the maximum file size and file system size the same?

In addition, the coolant understands this statement, "2.6 in the maximum (32-bit CPU) limit of the block device is 16TB, but ext3 only supports up to 4TB." Maximum file size and file system Is to shape.

The file system (ext3 / 4, xfs ...) are all theoretical and supported. Theoretical limits (16TB on ext3) are based on the underlying FS on-disk data structures, which have been tested is supported (4TB). Supported limits can vary widely in FS and depending on whether you want a large number of large files (ISO, image etc.) - small media or on small files (GIF - large percentage of disk) FS metadata Is required to store). Then file size and file system limitations are always different values.
