Dear all i am using the Contos07 , if am not installing anything in the root, then also "/dev/mapper/centos-root" this space is reduce by 100 MB everyday . Can you please help me to know how can i check in Linux that which thing is eating my space.
Try executing du -sh /dev/mapper/centos-root/* one day after and before.
This will provide a list of disk usage each day, so that you can compare what directories are incrementing in size.
Check your disk usage with `du -sh /*` to find large files or directories. Also, use `df -h` to monitor space and `journalctl --disk-usage` to check for log size issues.
If anyone else is having trouble reading the last post, which has some HTML embedded in it, the second and third commands are:
df -h
journalctl --disk-usage
