I use Amazon and I have an EC2 instance running CentOS 6.5.
I recently moved the disk from the machine. I did the procedure to shut down the machine to take a snapshot of the old disk and climb in a new one with the bigger space.
When I reconnected the machine it shows me that the partition bar is 7.8GB. When in fact the new disk is 20GB.
Command df -h:
Filesystem Size Used Avail Use% Mounted on
/dev/xvde 7,8G 7,3G 90M 99% /
tmpfs 828M 0 828M 0% /dev/shm
lsblk command:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvde 202:64 0 20G 0 disk /
xvdj 202:144 0 8G 0 disk
