I created a new backup system and initially tested everything with a 2.5TB disk. Once the idea worked out, I went to increase the disk to 7.5TB. I increase my volume on the SAN, then increased the disk in VMWare to 7.5TB. Then, went in to gParted and increased to 7.5TB but now im still seeing only 2.5TB total size on the disk when I do df -h

Here are the outputs of some needed information:

Paste from df -h

/dev/sdc                 2.5T   17G  2.3T   1% /usr/local/bananas/

Here is fdisk -l /dev/sdc

Disk /dev/sdc: 8246.3 GB, 8246337208320 bytes, 16106127360 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

experimental phase. Use at your own discretion.

From e2fsck -f /dev/sdc

[root@computer ~]# e2fsck -f /dev/sdc

Im running this on a Centos6 system. It looks like the disk is actually storing data properly but it won't go past 2.5TB even though everything else is showing it is set larger. Any ideas on this issue would be greatly appreciated!!!

    can you give us the result of df -Th – Hamza Jabbour Jul 28 '17 at 22:41
  • I've got the issues resolved by reformatting with XFS. However, your answer actually just helped me out. I've been using a different way to get the FS type of attached/additional disks. I actually never used -T in df this entire time. Whoops! Thanks for the tip! – saleetzo Jul 31 '17 at 17:25
  • Your Welcome ^^ – Hamza Jabbour Aug 1 '17 at 13:53
  • Well, I'm just saying, if your whole disk is a filesystem, why did you use fdisk on it…… – 炸鱼薯条德里克 Feb 21 at 11:07
  • definitely very helpful – saleetzo Feb 27 at 21:49

I just wiped out the partitions and then created a new partition, and then reformatted it as XFS. Everything is showing up properly in all forms of disk checking.
