A painful ucloud host disk resizing operation that causes data loss

Fault description:

I applied for an online ucloud host to build the zabbix monitoring platform. Recently, the data disk of this cloud host has reached 60 GB, and decided to resize the data disk from 80 GB to 200 GB, follow the ucloud official document http://docs.ucloud.cn/uhost/scaleup.html description, umount/dev/vdb1, and then execute e2fsck-F/dev/vdb with the following error

650) This. width = 650; "src ="/e/u261/themes/default/images/spacer.gif "style =" Background: URL ("/e/u261/lang/ZH-CN/images/localimage.png") No-repeat center; Border: 1px solid # DDD; "alt =" spacer.gif "/> 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M01/47/EC/wKiom1QEG0OzfRbcAAKnttRf1yI858.jpg "Title =" i56owc5swazxth@6elc@wbb.jpg "alt =" wkiom1qeg0ozfrbcaaknttrf1yi858.jpg "/>

The ucloud Technical Support Team suggested e2fsck-fy/dev/vdb, then we will not accept this error. Then, execute the subsequent operations. The tragedy is that all data is lost. This lesson is too big. before performing the operation, you should check with ucloud whether resizing the hard disk will lead to data loss. Now all the data is lost, and it is too late to regret it. No matter which provider, comprehensive evaluation is required when dangerous operations are involved. Do not trust the other party's documents or suggestions too much.
