[root#local ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
524G 465G 32G 94% /
/dev/sda1 99M 13M 82M 14% /boot
tmpfs 18G 0 18G 0% /dev/shm
[root#local ~]# du -hs /
57G /
Why the show is not the same, but I did not use so much space.

Chances are that you deleted a file that was still being written to. While it won't be picked up by du (it only looks at files that still 'exist"), df will notice the missing free space. Try a
lsof | grep deleted

I have my EC2 linux instance where some softwares are installed.
I downloaded a new zip and was trying to unzip it.
I got this error write error (disk full?). Continue? (y/n/^C) n
The zip is not corrupted and I can unzip it from other instances.
I change instance type from small to medium and then large.Nothing worked.
I ran df -h .
$ df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 16G 56K 16G 1% /dev
tmpfs 16G 0 16G 0% /dev/shm
/dev/xvda1 9.8G 9.7G 0 100% /
I think /dev/xvda1 is culprit. How can i increase the size of this?
What is this /dev/xvda1
It is not a matter of instance type. You must change the volume (EBS) size.
Go to console and select the EBS of that instance , click action dropdown menu , then click modify volume ( A form will appear with the current volume size, increase it )
Try to remove some kilobytes to be able to run (3). rm -rf /tmp/* for example.
Grow/Expand your filesystem :
sudo growpart /dev/xvda 1
sudo resize2fs /dev/xvda1
NOTES :
check Step(1) by lsblk command and check step (3 ) by df -h
Scale down your instance before receiving a huge billing the end of month 😅 ( Let it small as it was )

Why Linux df command still showing 100% disk used although I've delete some files. even lsof | grep delete show nothing? [closed]

Using df -Th show /folder usage 100%:
[root#gridtb007 ~]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda2 ext4 60G 58G 0 100% /
tmpfs tmpfs 24G 0 24G 0% /dev/shm

/dev/sdb1 ext4 917G 526G 346G 61% /data
AFS afs 8.6G 0 8.6G 0% /afs
Then, I delete in /root dir, however, df -TH still show / folder usage 100%. and I use lsof | grep delete show the lock process, and I Kill all the showd process, now lsof | grep delete show nothing, however, df -TH still show / folder usage 100%. Then I reboot the server, df -TH still show / folder usage 100%. So I don't know how to handle it.
df -Th /root shows this:
[root#gridtb007 ~]# df -Th /root
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda2 ext4 60G 58G 0 100% /
Just like #that other guy said
By default, 5% of space is reserved for root. Use% is the non-reserved part
I delete some files that are not so large, so there is still shown 100%. However, just as #Mark Plotnick said
Run find / -xdev -size +1000000 -ls to find all large files (>512MiB) on that filesystem
And then, I delete these large files, the FS show right capacity.

the /dev/mapper/ubuntu--vg-root is full.
how do i correct the problem please.?
thanx for all your support
You need to know what data is on it. So far I assume you have a whole OS in / only. What you can do is, for example, move some content to anoter volume (disk) and either mount it or make a symbolic link. I personally place /usr to a separate volume, and my /opt is a link. Then the root partition does not need to be so huge. But in your case the root has over 200 Gb what seems a bit more than the OS only :). Explore the files over there, perhaps you also find some movies if the user's home directories are also there...
find / -size +100M
The command above might be helpful to search for files over 100 Mb size (normally should not appear in root filesystem)
In order to free up disk space in dev/mapper/ubuntu--vg-root you can remove cached files with the following command:
sudo apt-get clean
You still can free up more space by uninstalling packages that are not required anymore:
sudo apt-get autoremove

I have the following output when I use df-i

/dev/sda3 17465344 17400194 65150 100% /

Then when i df -h

udev 12G 4.0K 12G 1% /dev
tmpfs 2.4G 644K 2.4G 1% /run
The problem is df -i , it return a 100% full which causes my apache2 &mysql unable restart or working well due to lack of disk space. any idea how do I increase my /dev/sda3 size on df -i because my df -h show that I only use 67% of the same place.
Thanks
Your problem isn't related with python. Your filesystem is full of files, and the inodes are exhausted.
These questions are related with your problem: https://unix.stackexchange.com/questions/26598/how-can-i-increase-the-number-of-inodes-in-an-ext4-filesystem and https://serverfault.com/questions/593298/how-to-increase-inodes.
I'm sorry for my English, a long time ago than I don't write in English.
This isn't a correct answer, probably a comment, but I'm not allowed to make comments.

I'm not able to edit any file on my linux machine.
I checked the free space available on my system,
df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 84K 16G 1% /dev/shm
tmpfs 16G 18M 16G 1% /run

/dev/mapper/fedora-home 428G 428G 0 100% /home
/dev/xvda1 477M 90M 358M 21% /boot
"/dev/mapper/fedora-home" is consuming complete memory, I'm not sure what this file signifies. How can I free the space consumed by this?
That's the partition where your home directory is located; since it's full, you won't be able to create new files anywhere under /home.
Delete some files in your home directory to free up space. If there are other users on the system, ask them to delete files they don't need as well.
Run the following commands to find big files in your $HOME
find ~ -type f -exec du {} + > /tmp/size_report.txt
sort -rn /tmp/size_report.txt | head -n20
and delete what you don't need from that list. Change the number from 20 to whatever to see more files.
