Hello

Disk 208GB seems full.(centos6.9 final) But it's not normal to be so big. What could be the problem?

Run du -x -m -d 1 / to find the top level directory that contains all the space. Repeat the same command, replacing / with the directory from that list that used the most space and keep repeating that process until you find the bottom of the tree where all the space has gone.

Ah, OK, thought we were in the CentOS 7 forum, for C6 you need to replace -d 1 with --max-depth 1

You have a stray '1' after -x in your command but
20137 /root
20G in /root?

46GB under /opt
69648 /
But only 69GB in total now - did you delete a bunch of stuff already?

Well you only have 69GB of files there so _something_ has most likely deleted some files that are currently open by a running process. When a file is open and is deleted then its entries in the directory are removed and it effectively vanishes... except for the things that had it open already which are still using it. The space used by those files is not released until the process(es) that have it open end or close the file.

If this is the case then running lsof | grep -i del will show the open deleted files so that you can restart the processes that are using it.
