I am benchmarking EXT4 performance on Compact Flash media. I have created an ext4 fs with block size of 65536. However I cannot mount it on ubuntu-10.10- ...

An ext4 filesystem is divided into block groups. Each block group has 8*blocksize (in bytes) number of blocks in it. If we consider the default ...

On ext4, just use tune2fs to check your block size, as follows (change /dev/sda1 to your own device path):

Valid block-size values are 1024, 2048 and 4096 bytes per block. If omitted, block-size is heuristically determined by the filesystem size and ...

ext4 allocates storage space in units of “blocks”. A block is a group of sectors between 1KiB and 64KiB, and the number of sectors must be an integral power of 2. Blocks are in turn grouped into larger units called block groups. Block size is specified at

ext4 ; 16-256 TiB (for 4-64 KiB block size) · 4 billion (specified at filesystem creation time) · 255 bytes (fewer for multibyte character encodings such as ...

When you create the ext4 file system with the default parameters, the filesystem will be created with a block size of 4 KB (4096 bytes) (see the ...

At the moment, the default size of a block is 4KiB, which is a commonly supported page size on most MMU-capable hardware. This is fortunate, as ...

So it appears to me that the maximum block size that you can define is 4096 KB.
