  • Linux Lite: 5.4 64bit

  • CPU: i5-5200

  • MEMORY: 8Gb

  • VIDEO CARD: nvidia geoforce 920m
Hey people,

I'm new here, I installed linux lite because I was looking for a light and simple look OS. It also made my PC faster and that was great. But a few weeks later i was having some disk usage problems when i was using it. I have double boot with windows.

My main problem with the disk usage is the % usage of the disk. Sometimes the % of disk shoot out to 100% just by executing some command, like opening the browser, or running some programs like matlab. I have checked the RAM usage with the task manager and there is no 100% RAM usage problem (I normally use around 60-70% RAM), and the hard drive I have is very pretty new.

When I get the % disk usage problem, i used iotop to know what was happening in the disk, I found that the last program that I have run appears using 99% of the disk, as well as other programs that had been running without problems. So several processes appear using 99% of the disk, which ends up blocking my computer and with no other choice but to use REISUB or simply the power button(sometimes REISUB doesn't work either ).

Has anybody present this same problem? and what should i do to fix it?  :'(

my thanks to the one who gives me some indication on what to do  ;D

  • MEMORY: 4Gb

  • VIDEO CARD: AMD Mullin Radeon R2//Intel//AMD/ATI RS880

  • Kernel: 5.x

@Nicksan I coukd see disk perf would go 100% utilization (read/write) not space utilization as 99% full unless the partition is sized funny.

How did you set up/install did you use alongside Windows or the Something else option??
How are the partitions setup...
Pasting the outputs of...
Code: [Select]
lsblk
df -hT
free -h

May help figure out???

Are you using timeshift on a schedule?

I'll leave you respond to firenice03's questions ... and maybe add, if the computer is a laptop and using a slooow 4200RPM standard HDD, could mean trouble.
If you have an SSD, forget I mentionned it ;)

Hi, my computer is a laptop, but using a ST1000LX015, hybrid 2.5", SATA 6GB/s, 5400rpm, 128MB. It is supposed to have a fairly high transfer rate by having a SSD portion  :shrug

Replace it with a real SSD drive.  Those hybrid drives are weird.

(please see forum rules about posting images).
Seems Firefox is opening a bunch of processes?
Also there is clamscan there, Im guessing the antivirus.
Everything trying to access the HDD at the same time could really bog down a system... Hybrid drives work fast on data already accessed recently, but at standard speed for everything else.
Maybe try to open less Firefox windows or stop the clam scan when needing to work?

in terminal write ncdu  if not on your computer it will tell you how. It is simple. This will give you at the top of a list what is taking up your disk space.

Oooh! I got an idea. If the disk is hybrid SSD but has not been "TRIM-ed" some performance issues are bound to occur, specially if an older drive.
Has to HOW to TRIM a drive, I have no clue, or if even possible on Hybrid drives.

I mean, is not because disk space, it's about % io disk usage :c
