I formatted my / and /home partitions as xfs. But now my root partition is going out of space and only around 800Mb is left on it.
I plan to format my windows partition (FAT32) and allocate around 2-3Gbs of space to root partition. I heard a lot about gparted but the iso image I downloaded was corrupted. I then downloaded PartitionMagic8.0 but it does not support XFS
Is there any other tool which can help me decrease(increase) my windows(root) partition without data loss cause I compiled most of the programs and if I lose my data then I am going to pull my hair off the head.

xfs_growfs is used for expanding xfs filesystem.

I read the page, but since I am not into all this command line stuff, I was not able to understand what alls written. I have /dev/sda4 as / partition and /dev/sda5 as the partition which I want to merge. Both are XFS. Can anybody please tell me how to merge the two partitions.
And yeah, sda4 is primary whereas sda5 is logical. Is this going to make any diffrence?

Go get gparted again - and run md5 against it.

I downloaded and installed it on my system.
But how can I use it to increase the size of root partition? I cant unmount it.

OK getting gparted again.
