Hello techrunnr readers, this document deals with issue “exact volume not showing in aws centos ec2”.
Here I have created an AWS Ec2 centos machine of 30Gb root hard disk. when I log in and check the server is was showing 6GB. Here is the method which I followed to solve this issue.
You Need root access to the server.
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 30G 0 disk
└─xvda1 202:1 0 6G 0 part /
$ sudo su
# yum install gdisk
....snip...
# gdisk /dev/xvda
Command (? for help): p
Disk /dev/xvda: 62914560 sectors, 30.0 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 1CB06BCB-6003-4826-8208-C368357EAEDE
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 20971486
Partitions will be aligned on 2048-sector boundaries
Total free space is 8388541 sectors (4.0 GiB)
Number Start (sector) End (sector) Size Code Name
1 2048 12584959 6.0 GiB EF00
From the above output, you can see I used 30GB HDD but only 6GB is available.
I then delete the partition table information and create a new partition. I accepted the defaults and when prompted for the ‘Hex code or GUID’ I input EF00 which I found when I printed out the disk information above.
Command (? for help): x
Expert command (? for help): g
Enter the disk's unique GUID ('R' to randomize): 1CB06BCB-6003-4826-8208-C368357EAEDE
The new disk GUID is 1CB06BCB-6003-4826-8208-C368357EAEDE
Expert command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): Y
OK; writing new GUID partition table (GPT) to /dev/xvda.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.
I then place gdisk into expert mode and set the unique GUID back to the original value that I got from the first print above. Finally write the new partition information to disk. At this point I rebooted and after reconnecting to the instance I now have access to all 30G.
