Creating new ebs volume is taking forever

[karmi]

Hi, the data bag format seems legit to me, and it certainly shouldn't take neither too long to attach the volume, nor to format it. But this morning AWS is having some issues in eu-west, what region is this?

//cc @vhyza, can you look at this, please?

Hi,

It's in us-east. I can see the new volume in the AWS console. But chef just loops forever.

Thanks,
Erling

It even says in the AWS console that it is attached correctly:

Attachment: i-NODEID (node-name):/dev/sda2 (attached)

But I can't see it with 'ls /dev/' on the box

I can see a /dev/xvda2 will try to change the values in the data bag. (I'm using Ubuntu 12.04 LTS)

@erlingwl Yes, the naming can differ, but usually /dev/sda* is just a symlink to /dev/xvda*... Can you see some device file like that in /dev/*?

[erlingwl]

@karmi no, I couldn't see any /dev/sda* symlinks. But changing to "/dev/xvdf" seemed to do the trick.

Thanks for the report and for the link, quoting for other people and Google here:

Some kernels use /dev/xvd* instead of /dev/sd*. In your case, if you have attached the volume with device name
/dev/sdh it would appear as /dev/xvdh in the machine.
