Resize a Current Partition
- A boot disk or Live CD, or Rescue System is required to run the commands below
I needed to shrink a 135gb ext3 partition to 35gb, leaving space for another partition.
parted //the debian program
The process: parted /dev/sda
p //print partitions
That should do it.
Create a Partition
Once the above resizing is done, and there unallocated space on the disks, type - cfdisk /dev/sda to see partitions. A new partition can be CREATED from the now available free space.
Choose the TYPE of the Partition required - ext3 or RAID etc.
In order to format the new partition created using cfdisk (above): mke2fs -j /dev/sda3
That should do it. cfdisk will show the format and partitions for you to check. mount /dev/sda3 /mnt/newfolder //will mount it.
Problems, Pitfalls, and Solutions
1. The space you shrink to - make sure to allow PLENTY of room for the filesystem!!!! 35gb turned out to leave 32gb!!
2. Now - if parted gives the following error: No Implementation: This ext2 filesystem has a rather strange layout! Parted can't resize this (yet).
You need to get the latest “testing” version of parted - v. 1.7 Debian sarge using 1.6. You will need to change /etc/apt/sources.list to move to testing (on rescue system) and upgrade. The new version of parted should work fine.
