redefine Linux partions

Hi All,

How do I redefine partitions in Linux. I already have file systems created and now need to redefine them to a bigger size. Any help is greatly appreciated.

Re: redefine Linux partions

You could also look at the 'parted' command (Partition Editor).

It allows you to re-size into freespace etc. etc.

Read the documentation before doing anything though, and make sure you have a backup!

Re: redefine Linux partions

Hi all,

cfdisk is NOT a good idea if you want to keep your data available.

You may use PowerQuest partition magic ( or equivalents.

After partitions are resized, you may need to resize filesystems using resize2fs or another utility that corresponds to your filesystem.

Good luck.

Re: redefine Linux partions

Some advice that does not require points.

Every time I messed with this stuff after installation I ended up reinstalling the OS.

The only hope for me as a HP-UX geek is lvm. The reports on that are mixed as some have reported problems with that.

I'd really have a good backup because cfdisk and fdisk are the tools I used to blow up two systems.
