The following is df -h result. /dev/mapper/centos-root is 100%.

I removed a lot of large files (nGB) in $HOME and $HOME/Downloads. But there is no change in df -h result.
Could you tell me where I should remove files to get more space on /dev/mapper/centos-root?
Your Home directory is mounted from partition
/dev/mapper/centos-home
Try deleting unimportant files for example in
/tmp/
If you want to examine the file sizes have a look at the du command
The following is df -i result. /dev/mapper/vg00-lv_var 6553600 6553600 0 100% /var

I am on a CentOs system, and df shows that I have a lot of disk spaces available:
See this command:
$ git pull
fatal: write error: No space left on device
$ df -h

And I am currently running the git pull command under /data1, which has 87% spaces left.
Why is that?

Maybe you are running out of inodes? Check with df -ih.
Some of my friends told me that larger swap partition is very bad like thousands of web hits/min should be possible on my server,
The swap space is 16 GB, and i installed centos7 with "CWP" -> Control web panel
with enable csf, should i consider decrease swap partition space if it possible without formatting the server and how? or there is a solution to maintain this space not to harm the server,,

I found that swap file i more effective and easier to do in my case, so i disabled the swap partition and created a swapfile instead..
Here how you do it exactly.
i have a problem with centOS and DirectAdmin,
i can't login to panel, because not space available for create session
when i run df -h command, get the following result:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos_server2-root 50G 50G 20K 100% /
devtmpfs 7.8G 0 7.8G 0% /dev

/dev/mapper/centos_server2-home 192G 124G 68G 65% /home
tmpfs 1.6G 0 1.6G 0% /run/user/0
how i can free up /dev/mapper/centos_server2-root ?
You can remove the old logs from your system.
For removing old log files, are your logs being rotated, e.g. do you have /var/log/messages, /var/log/messages.1, /var/log/messages.2.gz, etc, or maybe /var/log/messages-20101221, /var/log/messages-20101220.gz, etc?
The obvious way to remove those is by age, e.g.
# find /var/log -type f -mtime +14 -print
# find /var/log -type f -mtime +14 -exec rm '{}' \;
Found out here https://serverfault.com/questions/215179/centos-100-disk-full-how-to-remove-log-files-history-etc (by mikel)
Note: Use the rm command with cautious.
Can anyone tell me how do I check the current available volume, consumed space, on my Mongodb pod on the new Openshift Online Platform? After allocating around 4GB of space, I am unclear on what's the volume that has been consumed until now.
Any light thrown on this will help. Thank you.
You can run oc exec <mongodb_pod> -- df -H .
For example, I get the following output when I run it for the sample python app in my cluster:
$ oc exec os-sample-python-1-hrbq7 -- df -H

I have a problem which I can't find the answer to anywhere online - so I thought I would ask it here. Below is a code snippet of the directories in my Raspberry Pi. I have a 16GB SD Card installed in my Pi, and the total size of all those directories is only about 5GB. When I try and install anything it says "Out of Memory", and I have already cleared all log files, etc to try and free up space.
But the real question is, why does it say full when it has a 16GB card and I've only installed apache2 and php5 on it?

Thanks for any help.
Try to type in: raspi-config and after that a menu pops up, with the option to expand your file system.
