Prepare temporary VM disk

Create a temporary disk to contain the Access Gateway MS Azure disk image. Clone the image and associate it with a VM.

To prepare a disk mounted on a Microsoft Azure VM:

  1. Connect to the VM using the IP address from the prior task.ssh okta@AA.BB.CC.DD.
  2. Find the disk using dmesg| grep "SCSI disk" command.

    For example:

    # dmesg | grep "SCSI disk" [ 2.234786] sd 3:0:1:0: [sdb] Attached SCSI disk [ 2.243805] sd 0:0:0:0: [sda] Attached SCSI disk [ 2.503937] sd 5:0:0:0: [sdc] Attached SCSI disk

    Ubuntu 18.04 by default uses two disks /dev/sda and /dev/sdb. Making the third disk added in the last task /dev/sdc.

    In use disks can be confirmed using a command such as df -h | grep /dev/sd which will produce output similar to:/dev/sda1 29G 1.4G 28G 5% / /dev/sda15 105M 4.4M 100M 5% /boot/efi /dev/sdb1 16G 45M 15G 1% /mnt

  3. Create a primary disk partition using the sudo fdisk /dev/sdc command :

    For example:

    sudo fdisk /dev/sdc . . . Command (m for help) n Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p): p Partition number (1-4, default 1): 1 First sector (2048-1048575999, default 2048): Last sector, +sectors or +size{K,M,G,T,P} (2048-1048575999, default 1048575999):[cr] Command (m for help): w . . . Syncing disks.
  4. Create a pfile system on the disk the sudo mkfs -t ext4 /dev/sdc1 command as shown below :

    For example:

    sudo mkfs -t ext4 /dev/sdc1 mke2ds 1.44.1 . . . . . . Writing superblocsl and filesystem accounting information: done
  5. Create a mount point for the new disk using mkdir as shown below:
    sudo mkdir /datadrive
  6. Mount the disk to the new mount point using mount as shown below:
    sudo mount /dev/sdc1 /datadrive
  7. Determine the UUID of the disk using the blkid command as shown below:
    sudo -i blkid | grep sdc1 /dev/sdc1: UUID="1fcbf355-d641-4fcf-8817-0b4b492413ac" TYPE="ext4" PARTUUID="75642bad-01"
  8. Using an editor such as nano or vi add a new entry to /etc/fstab which should resemble:
    sudo nano /etc/fstab> UUID="1fcbf355-d641-4fcf-8817-0b4b492413ac" /datadrive ext4 defaults,nofail 1 2
  9. Reboot the VM, reconnect and verify that the new file system is mounted:
    sudo shutdown -r now ssh okta@ip address df -h | grep sdc1

    The new device should show approximate 467GB free.
