Resizing ext3 partitions (/usr) [file system management]

xxx_anuj_xxx · 11-28-2005, 05:23 PM

Hello everyone!
My system: Redhat enterprise4 + Fedora core 4 + Redhat enterprise3 + windows nt
At the installation time I created partitions and now I reached to a position (on RHEL4)where my /usr partition is near to 99% while other partitions have less usage and more free space.
Problem: I want to delete my winnt and Redhat3 (as i am not using them) partitions and then add the resulting free space to the RHEL4 and FC4.
How to resize my /usr partition as it has vital files, I tried to resize but so far unsuccessful

, I am sure there must be some proper way for resizing my partitions which I don't know.
thanks and regards

that doesn't make much sense to me, how about the output of:
df -h

I think one could use GNU parted for this purpose. It is sort of equivalent to the well-know Partition Magic in the wondows world. Another (excellent) option would be to buy Acronis DiskDirector. It contains a bootable CD with which you can manage almost a lot of partition types (Ext2/3, ReiserFS, FAT, NTFS). You can also move ext2/3 partitions, this is not possible with parted I believe.
