Migrating Data from SFS Capacity-Oriented to Another Type of File Systems
Solution Overview
You can migrate data from an SFS Capacity-Oriented file system to a General Purpose File System or an SFS Turbo file system.
In this solution, a Linux ECS is used to connect the SFS Capacity-Oriented file system and the destination file system.
Notes and Constraints
- Only Linux ECSs can be used to migrate data.
- The Linux ECS, SFS Capacity-Oriented file system, and the destination file system must be in the same VPC. If the destination file system is a General Purpose File System, you need to configure a VPC endpoint. For details, see Configure a VPC Endpoint.
- Incremental migration is supported, so you can only migrate the changed data.
Prerequisites
- You have created a Linux ECS.
- You have created an SFS Capacity-Oriented file system and a destination file system and have obtained their mount points.
Resource Planning
Table 1 describes the resource planning in this solution.
Procedure
- Log in to the ECS console.
- Log in to the created Linux ECS, which can access both the SFS Capacity-Oriented and the destination file systems.
- Mount the SFS Capacity-Oriented file system, which is file system 1 in this example.
mount -t nfs -o vers=3,timeo=600,noresvport,nolock [Mount point of file system 1] /mnt/src
- Mount the General Purpose File System or SFS Turbo file system, which file system 2 in this example.
mount -t nfs -o vers=3,timeo=600,noresvport,nolock [Mount point of file system 2] /mnt/dst
- Install the rclone tool on the Linux ECS.
wget https://downloads.rclone.org/v1.53.4/rclone-v1.53.4-linux-amd64.zip --no-check-certificate unzip rclone-v1.53.4-linux-amd64.zip chmod 0755 ./rclone-*/rclone cp ./rclone-*/rclone /usr/bin/ rm -rf ./rclone-*
NOTE:
The rclone tool does not retain the file permissions or owner group information on the source. Use the rsync tool if you have such requirements.
- Synchronize data to the destination file system.
rclone copy /mnt/src /mnt/dst -P --transfers 32 --checkers 64 --links --create-empty-src-dirs
NOTE:
The parameters are described as follows. Set transfers and checkers based on the system specifications.
- /mnt/src: source path
- /mnt/dst: destination path
- --transfers: number of files that can be transferred concurrently
- --checkers: number of local files that can be scanned concurrently
- -P: data copy progress
- --links: replicates the soft links from the source. They are saved as soft links in the destination.
- --copy-links: replicates the content of files to which the soft links point. They are saved as files rather than soft links in the destination.
- --create-empty-src-dirs: replicates the empty directories from the source to the destination.
After data synchronization is complete, go to the destination file system to check whether data is migrated.
Verification
- Log in to the Linux ECS.
- Check the file synchronization results in the destination file system.
cd /mnt/dst ls | wc -l
If the data volume is the same as that in the source file system, data is migrated successfully.
