Depends on what you are running.<BR /><BR />SEP Fri, 11 Feb 2005 11:10:06 GMT https://community.hpe.com/t5/operating-system-linux/increase-the-size-of-the-quot-usr-quot-and-quot-opt-quot/m-p/3483893#M16304 Steven E.

It is a program for creating, destroying, resizing, checking and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganising disk usage, copying data between hard disks and disk imaging.<BR /><BR />For more information gp to:<BR /><A href="http://www.gnu.org/software/parted" target="_blank">http://www.gnu.org/software/parted</A><BR /><BR />Regards,<BR />Ross Fri, 11 Feb 2005 11:16:37 GMT https://community.hpe.com/t5/operating-system-linux/increase-the-size-of-the-quot-usr-quot-and-quot-opt-quot/m-p/3483894#M16305 Ross Minkov 2005-02-11T11:16:37Z https://community.hpe.com/t5/operating-system-linux/increase-the-size-of-the-quot-usr-quot-and-quot-opt-quot/m-p/3483895#M16306 Right, you may use different tools [from gparted to Partition Magic], but in any case you should run full backup before.<BR /><BR />The only [almost] 100% safe way to resize filesystem it's LVM.
