Resize partition with parted
 

Hello,

I have a partition, which is 32GB and is mounted to / of the archlinux distribution.

I want to create another partition, I need about 5GB and I want to take them from this partition.

If I use parted to resize the partition will I lose any files?

Thank you

Now resizing the partitions without losing data is possible, But you have to move carefully.

First shrink your filesystem. check man resize2fs for ext2/3/4 and man resize_reiserfs. they are pretty simple to use but live resize may not be supported on your system, though

First run fsck and then resize2fs to 27G

after that use parted to resize partition with size 27G. Thick here is that new partition's starting point must be same as old partition. Take a note if you need to. If in doubt, post your commands before running here first.

Are you sure it's fsck -f? I read the man page and I cannot find a -f argument

-f forces to check clean file systems and it's actually option of what fsck runs for actual file system checking.

Ok, i have done fsck and resize2fs.
Now what should i do with parted?
This is the partition table, number 2 is the partition to be resized:

Note the non-human readable start number for Number 2

Important point is that start number must be same as before.
Before jumping to running the commnads, read help resize for figuring out right numbers.
