Migrating Data from Huawei Cloud PFS to Huawei Cloud OBS or Between PFS Systems

Parallel File System (PFS) is a high-performance semantic file system provided by Huawei Cloud OBS. It features access latency in milliseconds, TB/s-level bandwidth, and millions of IOPS.

PFS is a sub-product of OBS. Migrating data to PFS follows the same process as migrating to OBS.

If the hierarchies of files to be migrated are too deep, you are advised to create a migration task group to migrate the data. If you create a migration task for migration, listing objects may time out. As a result, the migration will be interrupted.

Migration Data Using a Synchronization Task

There are constraints on migrating data to a parallel file system using OMS.

  • If an object name ends with a slash (/), the object size must be zero. Otherwise, the object cannot be migrated.
  • An object name cannot contain consecutive slashes (/), for example, test//test.
  • At the same level, a file cannot have the same name as a folder.
