az_live_disk_resize.sh

# Reference: https://docs.microsoft.com/en-us/azure/virtual-machines/linux/expand-disks
# Accoring to the documentation, this is only supported for data disks only

# At the time of this writing, this feature is still experimental
# i. Opt-in as follows:
az feature register --namespace Microsoft.Compute --name LiveResize

RG=myResourceGroup
VM=myVmName

# ii. Find the name of the disk to be resized
az disk list \
    --resource-group myResourceGroup \
    --query '[*].{Name:name,Gb:diskSizeGb,Tier:accountType}' \
    --output table

# iii. Update disk to the desired size
az disk update \
    --resource-group $RG \
    --name myDataDiskName \
    --size-gb 200 \
    --sku Standard_HDD  # Other options:Premium_LRS, StandardSSD_LRS etc.

# Scenario: Sync data from a storage container to a VM running on azure
# Note: You cannot sync to a container that does not exist, for that use cp instead

# Scenario: Copy new files from local storage to azure
# You must append a sas token to the container URL if the host is not running on Azure
# Alternatively, you can authenticate with Azure AD
azcopy login --tenant-id <your-org-tenat-id>

# Troubleshooting
# a. Azure AD authentication error
# Run this before logging in: keyctl session workaroundSession

azure-vm-mount-data-disk.sh

# Find the name of the new block(aka disk) e.g. dev/sdc
lsblk -o NAME,HCTL,SIZE,MOUNTPOINT | grep -i "sd"

# Create a new MBR or GPT partition (If disk size is over 2TB use GPT)
sudo parted /dev/sdc --script mklabel gpt mkpart xfspart xfs 0% 100%

# Format disk to create a new XFS 
sudo mkfs.xfs /dev/sdc1

# Register new partition in the kernel
sudo partprobe /dev/sdc1

# Mount the new drive
sudo mount /dev/sdc1 /data

#------------------------------
# Optional: Automatically mount on boot
# i. Find the UID of /dev/sdc1
# sudo blkid
# ii. Add the following entry in /etc/fstab
# UUID=33333333-3b3b-3c3c-3d3d-3e3e3e3e3e3e   /data   xfs   defaults,nofail   1   2
