Many of the programs + are called <tt>fdisk</tt><A NAME="1533"> </A>, including the Linux one, or + variations thereof. Details on using the Linux <tt>fdisk</tt><A NAME="1535"> </A> + are given on its man page. The <tt>cfdisk</tt><A NAME="1537"> </A> command is similar + to <tt>fdisk</tt><A NAME="1539"> </A>, but has a nicer (full screen) user interface. +<P> + When using IDE disks, the boot partition (the partition + with the bootable kernel image files) must be completely + within the first 1024 cylinders. This is because the disk is + used via the BIOS during boot (before the system goes into + protected mode), and BIOS can't handle more than 1024 cylinders. + It is sometimes possible to use a boot partition that is only + partly within the first 1024 cylinders. This works as long + as all the files that are read with the BIOS are within the + first 1024 cylinders. Since this is difficult to arrange, + it is <em>a very bad idea</em> to do it; you never know when + a kernel update or disk defragmentation will result in an + unbootable system. Therefore, make sure your boot partition + is completely within the first 1024 cylinders. +<P> + Some newer versions of the BIOS and IDE disks can, in fact, + handle disks with more than 1024 cylinders. If you have such + a system, you can forget about the problem; if you aren't + quite sure of it, put it within the first 1024 cylinders. +<P> + Each partition should have an even number of sectors, since + the Linux filesystems use a 1 kB block size, i.e., two + sectors. An odd number of sectors will result in the last + sector being unused. This won't result in any problems, but + it is ugly, and some versions of <tt>fdisk</tt><A NAME="1541"> </A> will warn about + it. +<P> + Changing a partition's size usually requires first backing up + everything you want to save from that partition (preferably the + whole disk, just in case), deleting the partition, creating + new partition, then restoring everything to the new partition. + If the partition is growing, you may need to adjust the sizes + (and backup and restore) of the adjoining partitions as well. +<P> + Since changing partition sizes is painful, it is preferable to + get the partitions right + the first time, or have an effective and easy to use backup + system. If you're installing from a media that does not require + much human intervention (say, from CD-ROM, as opposed to floppies), + it is often easy to play with different configuration at first. + Since you don't already have data to back up, it is not so + painful to modify partition sizes several times. +<P> + There is a program for MS-DOS, called <tt>fips</tt><A NAME="1543"> </A>, which resizes + an MS-DOS partition without requiring the backup and restore, but + for other filesystems it is still necessary. +<P> +<HR><A NAME="tex2html805" HREF="node40.html"><IMG WIDTH=37 HEIGHT=24 ALIGN=BOTTOM ALT="next" SRC="./next_motif.gif"></A> <A NAME="tex2html803" HREF="node35.html"><IMG WIDTH=26 HEIGHT=24 ALIGN=BOTTOM ALT="up" SRC="./up_motif.gif"></A> <A NAME="tex2html797" HREF="node38.html"><IMG WIDTH=63 HEIGHT=24 ALIGN=BOTTOM ALT="previous" SRC="./previous_motif.gif"></A> <A NAME="tex2html807" HREF="node1.html"><IMG WIDTH=65 HEIGHT=24 ALIGN=BOTTOM ALT="contents" SRC="./contents_motif.gif"></A> <A NAME="tex2html808" HREF="node114.html"><IMG WIDTH=43 HEIGHT=24 ALIGN=BOTTOM ALT="index" SRC="./index_motif.gif"></A> <BR> +<B> Next:</B> <A NAME="tex2html806" HREF="node40.html">Device files and partitions</A> +<B>Up:</B> <A NAME="tex2html804" HREF="node35.html">Partitions</A> +<B> Previous:</B> <A NAME="tex2html798" HREF="node38.html">Partition types</A> +<P><ADDRESS> +<I>Lars Wirzenius <BR> +Sat Nov 15 02:32:11 EET 1997</I> +</ADDRESS> +</BODY> +</HTML> |
