I'm running a CentOS 7 VM, where I have a second disk (sdb), which I need to expand often. After expanding the disk and I open 'parted' so that I can create a new partition, the following error message is returned:
Error: The backup GPT table is not at the end of the disk, as it should be. This might mean that another operating system believes the disk is smaller. Fix, by moving the backup to the end (and removing the old backup)? Warning: Not all of the space available to /dev/sdb appears to be used, you can fix the GPT to use all of the space (an extra 10485760 blocks) or continue with the current setting?
If I type in Fix, the message disappears and I'm able to create the new partition.
Can someone advise if there is a chance of data corruption or breaking/deleting the data on the disk by using this method?
