<p></p> <p><b>New page</b></p><div>When a partition is set up with [[disklabel]] and one wants to use this partition as a [[filesystem]] the filesystem must first be created. The newfs command does this. <br /> <br /> <br /> To see what superblocks were written to an already newfs&#039;d filesystem one can use newfs -N on [[OpenBSD]]:<br /> # newfs -N /dev/rwd0a<br /> Warning: cylinder groups must have a multiple of 2 cylinders<br /> /dev/rwd0a: 2097648 sectors in 2081 cylinders of 16 tracks, 63 sectors<br /> 1024.2MB in 7 cyl groups (328 c/g, 161.44MB/g, 20608 i/g)<br /> super-block backups (for fsck -b #) at:<br /> 32, 330720, 661408, 992096, 1322784, 1653472, 1984160,<br /> <br /> &#039;&#039;This shouldn&#039;t wreck the filesystem in case, but just in case the author dump(8)&#039;ed this filesystem in case this hypothesis was wrong. All good 5 minutes later, whew.&#039;&#039;<br /> <br /> In [[Linux]] the newfs command is called [[mkfs]].</div>
