Extend the BTRFS volume on Azure

To extend a BTRFS volume on Azure, you'll need to follow these steps:

1. Identify the name of the BTRFS volume that you want to extend. You can do this by running the following command:

sudo btrfs filesystem show

This will show you a list of all the BTRFS volumes on your system, along with their names and sizes.

2. Stop any services or applications that are using the BTRFS volume that you want to extend.

3. Use the Azure portal or Azure CLI to extend the size of the Azure disk that the BTRFS volume is on. This will increase the available space on the disk, but not yet on the BTRFS volume itself.

4. Use the following command to resize the BTRFS volume to use the new space:

sudo btrfs filesystem resize max /path/to/mount/point

Replace "/path/to/mount/point" with the actual path to the mount point of the BTRFS volume that you want to extend.

5. Verify that the BTRFS volume has been extended by running the following command:

sudo btrfs filesystem show

This should show that the size of the BTRFS volume has been increased to the same size as the Azure disk.

6. Start any services or applications that were stopped in step 2.

That's it! Your BTRFS volume on Azure should now be extended to use the additional space on the Azure disk.

Upskilling is Survival

Upskilling is no longer a “nice to have” for leaders. It's " SURVIVAL " The unpleasant reality? The moment they begin managing, most leaders stop learning. While the world moves more quickly than their perspective, they rely on prior experiences. Technology evolves. Teams evolve. Expectations change throughout time. You become the bottleneck if you don't. Today, being a leader isn't about knowing everything. It's about remaining current enough to pose pertinent queries. The most effective leaders I've encountered: Acquire knowledge more quickly than their teams Continue to be involved in change Invest in your abilities before they become essential. If you’re not actively upskilling, you’re not leading you’re just holding position. And in today’s market, that’s a risk you can’t afford.

Audiobooks and its Benefits

 What is Audiobook? An audiobook is a recorded reading of a book or other written work, typically on a CD or as a digital download. Audiobooks can be listened to on a variety of devices, such as smartphones, tablets, and laptops, and are often narrated by professional voice actors. They can be a convenient and accessible way to enjoy literature, and have been shown to improve vocabulary and comprehension, especially in children.
