The 2 GB of disk space is removed from the partition sdb1 of the Btrfs filesystem mounted on the /data directory. As you can see in the illustration, the Btrfs filesystem is resized (shrank) to 18 GB from 20 GB.

4. Delete and recreate the partition the file system is on to the required amount. ...
5. Mount the file system and partition.

Does Btrfs need to be defragmented?

This is how the Copy-on-Write (CoW) feature of the Btrfs filesystem causes fragmentation. Fragmentation means that the data extents of large files are scattered around the entire storage device. ... To solve this problem, it is necessary to defragment the Btrfs filesystem every once in a while.

Is Btrfs faster than ext4?

For pure data storage, however, the btrfs is the winner over the ext4, but time still will tell. Till the moment, the ext4 seems to be a better choice on the desktop system since it is presented as a default file system, as well as it is faster than the btrfs when transferring files.

How do you increase SDA size?

3 Answers. Make sure that you have parted version 3.2, then run parted /dev/sda and use the resizepart command to resize sda2, moving the end of the partition to the end of the disk. Then run resize2fs /dev/sda2 to enlarge the filesystem to use the additional space. Reboot not required.

How do I resize with Gparted?

How to do it...

1. Select the partition with plenty of free space.
2. Choose the Partition | Resize/Move menu option and a Resize/Move window is displayed.
3. Click on the left-hand side of the partition and drag it to the right so that the free space is reduced by half.
4. Click on Resize/Move to queue the operation.

Can I resize Linux partition from Windows?

Now, right click on the partition you want to change, and choose Shrink or Grow depending on what you want to do.

What does Btrfs balance do?

What btrfs balance does is to send things back through the allocator, which results in space usage in the chunks being compacted. ... By compacting space usage like this, the balance operation is then able to delete the now empty chunks, and thus frees up room for the allocation of new chunks.

What is Btrfs scrub?

btrfs scrub is used to scrub a btrfs filesystem, which will read all data and metadata blocks from all devices and verify checksums. Automatically repair corrupted blocks if there's a correct copy available. ... The scrubbing status is recorded in /var/lib/btrfs/ in textual files named scrub.

How do I defrag my Synology NAS?

To perform file system defragmentation:

Launch Storage Manager. Go to Volume. Select the volume on which to perform file system defragmentation. Select File System Defragmentation from the Action drop-down menu.

Is Btrfs slow?

btrfs is always going to be slow in write heavy workloads due to being a COW filesystem. If you need the extra speed in that specific workload why not just disable the COW features using chattrib.

Should I choose Btrfs or ext4?

Btrfs or EXT4. ... But generally, EXT4 is performing faster if speed is what you need. Otherwise, BTRFS offer so much more functionality and protection mechanisms. In order to change file system, you will need to set up the NAS from scrash and then select the file system and copy the data.

Should I use Btrfs or XFS?

Advantages of Btrfs over XFS

The Btrfs filesystem is a modern Copy-on-Write (CoW) filesystem designed for high-capacity and high-performance storage servers. XFS is also a high-performance 64-bit journaling filesystem that is also capable of parallel I/O operations.
