How to Resize a Live Filesystem on Linux

Before anything else, BACKUP your stuff! This method is risky, and only works on ext2/3/4 filesystems
Use fdisk /dev/sda to check current start/end sectors
Use fdisk to delete the partition
Use fdisk to create a new partition with same starting sector, but new end sector.
Verify that your changes are what you want.
Write fdisk changes.
Verify the new partition is the expected size.
Use sudo resize2fs /dev/sda1 to resize the filesystem to utilize all space in the new partition.
Verify the partition is the expected size.
Reboot for safety.

You seriously don't know the pain I went through in searching for a perfect videos which shows a live partition using a terminal.

You brother made my day. Thanks a lot. Bless you 😇.

This is a really good tutorial. The author is really cautious. Everything works fine for me, thank you.

This really helped me out. Resized vm drive on open media vault. Worked perfectly. Only slight confusing part was partition number. I guess if it is sdb1 its 1 if it is sdb2 its 2... anyway I chose 1 for sdb1 and it worked perfectly. I took a backup before (524g of video). be sure and backup this is risky.

This really helped me to solve my resize problem in ubuntu server 18.04 LTS.

It is 2am on a random night after a super shitty day and I can't believe resizing my filesystem live would bring back my spark. Thanks man : )

[M.C.D.Technologies]

Thanks a bunch, I ended up doing a clone of an OMV install from a smaller drive to a larger one and even GParted would not let me extend the volume. This, however, worked a treat, keep up the great work and thank you.

[DanJackielz]

This helped me out a lot! Very easy to understand.

[prapulkrishna]

This is very well explained thanks for the video.

[jamesamestosopalin]

can you increase the size of partition sda1 without deleting and creating new partition?

[benjamindreyer]

This works great but what if the unallocated space and the partition you are trying to resize have partitions in between them? this way you will overwrite the other partitions because you can't make it bigger

[DonProshetsky]

Good video but after I modify my volume by adding 35GB, performing the commands as per this video doesn't allow me to extend my logical partition (value out of range)

Reboot causes me to lose my space gained. In df I go from 73G to 88G after running resize2fs /dev/sda2. After reboot it goes back to 73G. Any idea what might be causing that?
