One of my client is facing disk space issue on his Cheap Linux VPS Server but disk space is still available there in another partition.
He asked me for help.
I checked disk space on his server and I got below results:
root@server [~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_server-lv_root 50G 45G 2.5G 95% /
tmpfs 7.8G 0 7.8G 0% /dev/shm
/dev/sda1 477M 77M 376M 17% /boot
/dev/mapper/vg_server-lv_home 860G 2.7G 814G 1% /home
In this tutorial I am going to use /var folder disk space in /homefolder with the help of soft link concept
As we can see that space is available more then 800GB in /home partition but we are facing issues in / partition due to log folder is making disk space full in / partition.
The client asked me why his Reliable Managed Linux VPS Server is crashed again and again due to a space issue his backup is also failing due to this.
I explained to him that there are only 50 GB of space is assigned to / directory and it’s already full.
There are 2 ways to resolve this issue.
One that he reassign space from /home to /.
but it creates some issue server down, data loss and he is already don’t have a backup for more than 1 week.
So we decided to use another solution
We used soft link as a solution we moved his /var/log folder to /home/var/ directory and then created soft link form /var/log to /home/var/log to resolve his issue.
here is the standard command to create the soft link:
ln -s path-to-actual-folder name-of-link
to confirm, do:
ls -ld name-of-link
We ran the following command on the server to create soft link:
ln -s /home/var/log/ log
then we verified it with the command:
root@server [/var]# ls -ld log
lrwxrwxrwx 1 root root 14 Jun 16 03:03 log -> /home/var/log/
we have restarted all services on his server and also check his website everything is working fine.
