![]() This is the number of blocks read or written to disk before moving to Stride= stride-size Configure the filesystem for a RAID array with stride-size filesystem blocks. The -R option is still accepted for backwards compatibility. ![]() Used to be -R in earlier versions of mke2fs. Extended options are comma separated, and may take an argument using the equals ('=') sign. E extended-options Set extended options for the filesystem. If this option is specified twice, then a slower read-write test is used instead of a fast c Check the device for bad blocks before creating the file system. This is useful forĬertain hardware devices which require that the blocksize be a multiple of 2k. Heuristics to determine the appropriate block size, with the constraint that the block size will be at least block-size bytes. If block-size is negative, then mke2fs will use The filesystem size and the expected usage of the filesystem (see the -T option). If omitted, block-size is heuristically determined by Valid block-size values are 1024, 20 bytes per block. Options -b block-size Specify the size of blocks in bytes. See the nf(5) manual page for more details. The defaults of the parameters for the newly created filesystem, if not overridden by the options listed below, are controlled by the If called as mkfs.ext3 a journal is created as if the -j option was specified. Mke2fs automagically figures the file system size. blocks-count is the number of blocks on the device. Mke2fs -O journal_dev ĭescription mke2fs is used to create an ext2, ext3, or ext4 filesystem, usually in a disk partition.ĭevice is the special file corresponding to the device (e.g /dev/hdXX).
