#Increase the size of the EBS volumes to 50 GiB from 100 GiB using the AWS CLI. Do this once for each EBS volume.

/etc/init.d/oracleasm querydisk -d DATA1

#After finding the disk major and minor number (from the previous command), use the following command to find the device name at the OS level

ls -la /dev/ | grep <replace-with-disk-major-number-from-previous-command> | grep <replace-with-disk-minor-number-from-previous-command>

#Use the fdisk command to resize the partition
