Hello everyone! I recently faced a seemingly simple task \u2014 to increase the disk size on a Linux server 'on the fly'.<\/p>\n

Task Description<\/h4>\n

\nI have a cloud server. In my case, it\u2019s Google Cloud \u2014 Compute Engine. The operating system is Ubuntu. Currently, there is a disk size of 30 GB connected. The database is growing, files are inflating, so I need to increase the disk size, say, to 50 GB. Meanwhile, we won't turn anything off or reboot.
\n<\/a><\/noindex>
\nAttention! Before starting, make a backup of all important information!<\/b><\/p>\n

1. First, let's check how much free space we have in total. In the Linux console, we write:<\/p>\n

df -h<\/code><\/pre>\n
\n\"How
\nSimply put, I have 30 GB in total and 7.9 GB currently free. It needs to be increased.<\/i><\/p>\n
2. Next, I go to my hosting provider's console and attach a bit more GB. In Google Cloud, this is done easily, without rebooting. I go to Compute Engine -> Disks -> Select the disk of my server \u2014 we will change its size:<\/p>\n
\"How
\nI enter, click 'Edit', and increase the disk size to the desired dimensions (in my case, to 50 GB).<\/i><\/p>\n
3. So, now we have 50 GB. Let's check this with server<\/a> with the command:<\/p>\n
sudo fdisk -l<\/code><\/pre>\n
\n\"How
\nWe see our new 50 GB, but currently, we can only use 30 GB.<\/i><\/p>\n
4. Now we will delete the current 30 GB partition and create a new one for 50 GB. You may have several partitions. You might need to create a few new partitions as well. For this operation, we will use the program fdisk<\/b>, which allows managing hard disk partitions. It\u2019s also important to understand what disk partitions are and their purposes \u2014 read here<\/a><\/noindex>. To launch the program fdisk<\/b> we use the command:<\/p>\n
sudo fdisk \/dev\/sda<\/code><\/pre>\n
\n5. Inside the interactive mode of the program fdisk<\/b> we perform several operations. <\/p>\n
First, we type in:<\/p>\n
p<\/code><\/pre>\n
\n\"How
\nThe command outputs a list of our current partitions. In my case, there is one partition of 30 GB and another 20 GB floating free, so to speak.<\/i><\/p>\n
6. Next, we type in:<\/p>\n
d<\/code><\/pre>\n
\n\"How
\nWe delete the current partition to create a new one for all 50 GB. Before the operation, double-check if we've made a backup of important information!<\/b><\/i><\/p>\n
7. Next, we specify to the program:<\/p>\n
n<\/code><\/pre>\n
\n\"How
\nThe command creates a new partition. All parameters should be set to default \u2014 you can just hit Enter. If you have a specific case, specify your own parameters. As shown in the screenshot, I created a partition of 50 GB \u2014 just what I need.<\/i><\/p>\n
8. As a result, I specify to the program:<\/p>\n
w<\/code><\/pre>\n
\n\"How
\nThis command writes the changes and exits. fdisk<\/b>Don't be alarmed that reading the partition table failed. The next command will help fix this. We're almost there.<\/i><\/p>\n
9. We exited fdisk<\/b> and returned to the main Linux command line. Next, we type as advised earlier:<\/p>\n
sudo partprobe \/dev\/sda<\/code><\/pre>\n
\nIf everything goes well, you won't see any message. If you don't have the program partprobe<\/b>, then install it. This will partprobe<\/b> update the partition tables, allowing us to extend the partition to 50 GB online. Let's continue.<\/i><\/p>\n
Tip! You can install partprobe<\/b> like this:<\/p>\n
 apt-get install partprobe<\/code><\/pre>\n
<\/i>
\n10. Now we need to redefine the partition size using the program resize2fs<\/b>. It will do this online \u2014 I even had scripts running and writing to the disk at that moment. <\/p>\n
Program resize2fs<\/b> will rewrite the filesystem metadata. For this, we use the following command:<\/p>\n
sudo resize2fs \/dev\/sda1<\/code><\/pre>\n
\n\"How
\nHere sda1 is the name of your partition. In most cases, it's sda1, but there may be exceptions. Be careful. As a result, the program changed our partition size. I think this is a success.<\/i><\/p>\n
11. Now let's make sure that the partition size has changed and we now have 50 GB. To do this, we repeat the very first command:<\/p>\n
df -h<\/code><\/pre>\n
\n\"How
\n
