Mounting and formatting the right volume at Hyperstack

I’ve been exploring Hyperstack for cloud GPU access. Like many cloud compute services, you can create disk volumes and mount them. But because I had to (a) format it 😅 and (b) couldn’t figure out how to identify which disk was which, I’m logging the commands here. 

Step 1: Identify the device with lsblk by disk size:

$ lsblk
NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
loop0     7:0    0    64M  1 loop /snap/core20/2379
loop1     7:1    0  63.9M  1 loop /snap/core20/2318
loop2     7:2    0 114.4M  1 loop /snap/lxd/26741
loop3     7:3    0    87M  1 loop /snap/lxd/29351
loop4     7:4    0  40.4M  1 loop /snap/snapd/20671
loop5     7:5    0  38.8M  1 loop /snap/snapd/21759
vda     253:0    0   200G  0 disk
├─vda1  253:1    0 199.9G  0 part /
├─vda14 253:14   0     4M  0 part
└─vda15 253:15   0   106M  0 part /boot/efi
vdb     253:16   0   200G  0 disk /mnt/batch01
vdc     253:32   0    20G  0 disk 

It’s that last one I was looking for.

Step 2: Everything else is business as usual:

$ sudo mkfs.ext4 /dev/vdc
$ sudo mkdir /mnt/batch02
$ sudo mount /dev/vdc /mnt/batch02

The image I’m running from is Ubuntu-like.
