Expanding /dev/sda6 disk? (after adding space to the virtual machine)

[Being]

I added more disk space in VMware to the linux server, the OS has not recognized the added disk space yet. I want to expand the existing disk "/dev/sda6" to use this new space.. how is that done in Linux OpenSuse ?

If it is an ext2/3/4 file system, then you can use the resize2fs command to expand the file system accordingly. I do this quite frequently. Expansion in-place is a lot easier than shrinking the file system. In fact, to expand a file system/partition with resize2fs doesn't even require that you take it offline.

How can i tell if "it is an ext2/3/4 file system" ? on a linux openSuse machine?

thank you

The "mount" command will show you what file system types are mounted on which devices/partitions. In any case, most Linux file systems are ext2/3/4 types. If you run resize2fs on a non-ext2 derived file system (which ext3 and ext4 are), then it will let you know and not do anything untoward.

more deailss (see below for the mount results)

I guess that's good news its on ext4

But, will i need to unmount something first?

Pretty much!

Do i need to un-mount the partition first?

[Being]

This is what I get

resize2fs 1.41.14 (22-Dec-2010)
open: No such file or directory while opening ext4

Not to expand the partition/file-system. Only if you are going to shrink it.

Using: resize2fs ext4 104857600

gave me" "No such file or directory while opening ext4"

am i using the resize2fs command incorrectly to get that error?

how about using gparted?
