The most basic storage layout concept of ext4 is Block. ext4 allocates storage in a series of blocks, just like LBA. However the ext4 Block size can be different. Block size in Superblock is 4096B = 4KB. There are Block count, 3908091, number of blocks in this filesystem. The second basic storage layout concept of ext4 is Block Group.

The logical block size is the number of bytes read or written by the operating system in a single I/O operation. Valid values for blocksize are 512, 1024, and 2048. The default is 1024. special mkfs constructs a file system by writing on the special file. size Specify the number of logical 512 byte sectors in the file system. The largest file system size is a maximum of 2,097,152 512-byte sectors (1 gigabyte).

mkfs.ext4: 65536-byte blocks too big for system (max 4096) In detail I have a server hardware with a RAID5 with 5 SSDs for OS and DDB. And a RAID6 with 12 x 8 TB SAS harddisks for the disklibrary.

  • The size argument is the number of blocks to be used for the filesystem. The exit code returned by mkfs is 0 on success and 1 on failure. In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux.

    In practice, this value is limited by the filesystem block size (named sectorsize at mkfs time), and memory page size of the system. In case of sectorsize limit, there’s some space unavailable due to leaf headers. For example, a 4k sectorsize, maximum size of inline data is about 3900 bytes.

    the current mkfs.jffs2 util has in its --eraseblock handling: /* If it's less than 8KiB, they're not allowed */ if (erase_block_size < 0x2000) { fprintf (stderr, "Erase size 0x%x too small.

Only block counts strictly greater than 10 and strictly less than 65536 are allowed. OPTIONS-c, --check Check the device for bad blocks before creating the filesystem.

    Specify the size of blocks in bytes. Valid block-size values are 1024, 2048 and 4096 bytes per block. If omitted, block-size is heuristically determined by the filesystem size and the expected usage of the filesystem (see the -T option). If block-size is preceded by a negative sign ('-'), then mke2fs will use heuristics to determine the appropriate block size, with the constraint that the block size will be at least block-size bytes. This is useful for certain hardware devices which require ...
