What happened : Linux Redhat server – toot file system was almost full.Removed unneeded files ,but file system still is full.du command shows very small amount of space are used.

Reason is that ,some processes still were using those user files ,even users said they don’t need them.

Solution: run lsof | grep delete

Check second and fourth columns

cd /proc/<second column from output>/fd

echo > <number portion from fourth row>

Repeat that for each ,specially for large files and you will see right file system size from df command
