CentOS 6 ran out of space, need to reclaim it
Hello everyone,

I am having an issue here with CentOS release 6.6 (Final) that shows all of the space used up, but I can't tell where the space went.

Seemingly I am using up 100%, according to

Code:
df -h

Filesystem                     Size  Used Avail Use% Mounted on
/dev/mapper/vg_sugar-lv_root   50G   49G     0 100% /

So that's 49G out of 50G, fair enough, but when I try to see what exactly is being used (x to remove mounts):

Code:
du -xsh /*

1.8G    /usr
2.0G    /var

That's all, these are the 2 biggest directories, all others combined are under 1G.

Here is info on Disk /dev/mapper/vg_sugar-lv_root, it does show close to 50G (this is a virtual machine):
Code:
fdisk -l

Disk /dev/mapper/vg_sugar-lv_root: 53.7 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Node count is at 7%:
Code:
df -i

Filesystem                   Inodes  IUsed     IFree   IUse% Mounted on
/dev/mapper/vg_sugar-lv_root 3276800 200552    3076248    7% /

The system was rebooted several times, so any log files should've been deleted. I'd appreciate some tips in resolving this.

Code:
find / -xdev -type f -size +100M

returned only a single file. The problem is not in amount of large files, but that the space is hidden or used for something else, or not released.
Code:
 du -ahx / | sort -rh | head -20 
5.0G / 
2.0G /var 
1.8G /usr
1.1G /var/lib 
945M /var/lib/mysql 
909M /var/lib/mysql/sugarcrm 
759M /var/www 
745M /var/www/html 
707M /root 
672M /usr/lib64 
642M /var/www/html/sugar 
611M /usr/share 
480M /var/lib/mysql/sugarcrm/emails_text.MYD 
441M /lib 
392M /lib/modules 

228M /usr/lib
