If I Detach a Disk, Will I Lose the Data on My Disk?

Data on a disk will not be lost after the disk is detached, and the disk can be re-attached later if needed.

To ensure your data safety, you are advised to follow the instructions described in Disk Detachment Process.

For disks not supporting online detachment:
1. Stop the server where the disk was attached.
2. After the server has stopped, detach the disk.
For disks supporting online detachment:
Detach the disk from a running ECS. For details, see Management > Detaching an EVS Disk from a Running ECS in the Elastic Cloud Server User Guide.
