在不丟失任何數(shù)據(jù)的情況下增加EC2磁盤存儲(chǔ)

我們可以在不分離卷或重新啟動(dòng)實(shí)例的情況下增加ebs卷。最好創(chuàng)建ebs卷的快照，以防發(fā)生不好的情況

用于創(chuàng)建快照

Go to your EBS volume list from your EC2 Dashboard.
Right click the volume.
Click Create Snapshot link.
Add the description value any thing is good here.
Add key : Name and value : snapshot-your-volume.
Click button Create Snapshot.

增大尺寸

Right click on the volume you wish to increase.
Add your desired size; In our example type 40.
Click Modify.
You will get confirmation to extend OS file system.
Click Yes.

修改完卷后，需要擴(kuò)展操作系統(tǒng)文件系統(tǒng)以查看增加的卷大小。

ssh into your instance 
df -h -> will tell you the volume size
lsblk -> display information about the block devices attached to your instance
sudo growpart /dev/xvda 1
df -h -> to verify the size again
sudo resize2fs /dev/xvda1
