Disk Space used shows more than file size in folder

Hello All,

I am extremely new to virtualization of servers. I have XENServer 5.5. I am facing a problem that I have not seen before. Unfortunately my admin is off on vacation and I am not very familiar. Kindly help me out.

The problem is that when I do a df h the /mnt/arep2 mount shows the amount of used space to be 126GB.

[root@mysql-2a ~]# df -h

Filesystem Size Used Avail Use% Mounted on


18G 2.6G 14G 16% /

/dev/xvda1 99M 19M 76M 20% /boot

tmpfs 1.1G 0 1.1G 0% /dev/shm 396G 342G 35G 91% /mnt/arep1 132G 126G 0 100% /mnt/arep2 26G 15G 11G 59% /mnt/arep3

However I am using only 82 GB of the space. The rest of the space is not showing up for some reason. There are no hidden files.

[root@mysql-2a arep2]# ls -lrt

total 80640908

-rw-rw---- 1 mysql mysql 64424509440 Oct 19 09:44 ibdata2-1a

-rw-rw---- 1 mysql mysql 18222583808 Oct 28 22:41 ibdata2-2a

I searched the internet for quite some time for a resolution. There were a few topics which suggested that this could be due to some kind of recovery process on virtual servers which takes snapshots of the disk used at various intervals of time.

Please let me know how to recover this situation as I need the disk space that I lost
