| 19 | .SH DESCRIPTION | |
| 20 | .B mkfs | |
| 21 | creates a Linux MINIX file-system on a device (usually a disk partition). | |
| 22 | ||
| 23 | The | |
| 24 | .I device | |
| 25 | is usually of the following form: | |
| 26 | ||
| 27 | .nf | |
| 28 | .RS | |
| 29 | /dev/hda[1-8] | |
| 30 | /dev/hdb[1-8] | |
| 31 | /dev/sda[1-8] | |
| 32 | /dev/sdb[1-8] | |
| 33 | .RE | |
| 34 | .fi | |
| 35 | ||
| 36 | The | |
| 37 | .I size-in-blocks | |
| 38 | parameter is the desired size of the file system, in blocks. This | |
| 39 | information can be determined from the | |
| 40 | .BR fdisk (8) | |
| 41 | program. Only block counts strictly greater than 10 and strictly less than | |
| 42 | 65536 are allowed. | |
| 43 | .SH OPTIONS | |
| 44 | .TP | |
| 45 | .B \-c | |
| 46 | Check the device for bad blocks before creating the file system. If any | |
| 47 | are found, the count is printed. | |
| 48 | .TP | |
| 49 | .BI \-n " namelength" | |
| 50 | Specify the maximum length of filenames. No space is allowed between the | |
| 51 | .B \-n | |
| 52 | and the | |
| 53 | .IR namelength. Currently, the only allowable | |
| 54 | values are 14 and 30. | |
| 55 | .B 30 is the default. | |
| 56 | .TP | |
| 57 | .BI \-i " inodecount" | |
| 58 | Specify the number of inodes for the filesystem. | |
| 59 | .TP | |
| 60 | .BI \-l " filename" | |
| 61 | Read the bad blocks list from | |
| 62 | .IR filename . | |
| 63 | The file has one bad block number per line. The count of bad blocks read | |
| 64 | is printed. | |
| 65 | .SH "EXIT CODES" | |
| 66 | The exit code returned by | |
| 67 | .B mkfs.minix | |
| 68 | is one of the following: | |
| 69 | .IP 0 | |
| 70 | No errors | |
| 71 | .IP 8 | |
| 72 | Operational error | |
| 73 | .IP 16 | |
| 74 | Usage or syntax error | |
