Disc Defragmentation/Checksum

Hello,
How do you do a disk defrag, checksum?

Is anybody available to answer. Is this not possible.

Generally, you don’t need to defrag a ext4 filesystem on EOS, as the filesystem is built to prevent fragmentation. Nonetheless it can occur on some rare occasions. You can check the degree of fragmentation with:

sudo e4defrag -c $(mount | grep sysroot | awk '{print $1}')

If needed, you can then run the defragmentation:

sudo e4defrag $(mount | grep sysroot | awk '{print $1}')

Thank you for your answer. I also just found out that the onscreen keyboard doesn’t show on the screen anymore. This must have happened after an update. Before, I could turn on the onscreen keyboard from Settings-Universal Access. Now Universal Access has been replaced with Accessiblity. When i turn on the onscreen keyboard it doesn’t load on the screen anymore. The look of the Settings screen also looks different.
