Attach volume on host OS

This Gist describe how to create and attach virtual disk to the VM The source article can be found here.

Initialize new data disk in Linux

• SSH to the VM: ssh -i ~/ssh/ssh_identity_file user@server_ip
• Find the SCSI device identifier (of the attached volume) using lsscsi
• Install lsscsi if needed: sudo yum install lsscsi

For the next steps, we assume the new volume is called /dev/sdc

• sudo fdisk /dev/sdc
• type ''n'' to create partition
• select ''p'' for primary partition
• type 1 to make it the first partition
• Type ''p'' to see details about the disk
• Type ''w'' to write settings for the new disk

Create a file system on the newly created disk and mount it

• sudo mkfs -t ext4 /dev/sdc1
• Make a directory to mount the new file system: sudo mkdir /datadrive
• Mount the drive to the directory: sudo mount /dev/sdc1 /datadrive

Add the new drive to /etc/fstab

• Find the UUID of the new drive: sudo -i blkid
• Edit /etc/fstab in text editor: sudo nano /etc/fstab
• Add line to /etc/fstab: (replace UUID value) UUID=33333333-3b3b-3c3c-3d3d-3e3e3e3e3e3e /datadrive ext4 defaults,nofail 1 2

Test if file system mounted properly:

• Unmount the directory: sudo umount /datadrive
• Mount back the directory: sudo mount /datadrive

Make writable:

• Make the drive writable: sudo chmod go+w /datadrive
