Trying to resize2fs EB volume fails

Question

I have a 200GB EBS volume and am trying to increase the space available. I followed the instructions on: http://www.hellersoftware.com/2012/resize-ebs-volume-attached-to-amazon-web-services-ec2-instance/ and managed to create a snapshot and create a new EBS based on that snapshot. Everything is peachy, except when I do: `# resize2fs /dev/sdf` I get ``` resize2fs 1.40.8 (13-Mar-2008) resize2fs: Bad magic number in super-block while trying to open /dev/sdf Couldn't find valid filesystem superblock. ``` Not sure what's going on there, but my new volume still only shows 200GB, when in fact it's an 800GB volume.

Accepted Answer

The OP stated that he was using the XFS filesystem. The tool `resize2fs` works with ext2, ext3 and ext4 only.

There's a similar tool available for the XFS filesytem called xfs_growfs. You'll most likely have to install it first

```
sudo yum install xfsprogs.x86_64 --assumeyes
```

then mount your filesystem

```
sudo mount -t xfs /dev/sdf /vol
```

now you can extend the filesystem

```
sudo xfs_growfs /vol
```

`df -h` should now show more available space

I hope this helped :)

Tip: ext4 filesystem is the recommended filesystem for EBS volumes ( for the future )
