Introduction to obsfs

Functions

• obsfs lets you mount an OBS parallel file system to your local Linux file system, so that you can manage objects stored in OBS as if they were stored locally.
• obsfs synchronously uploads any incremental file from the local mount directory to OBS.
• obsfs synchronizes objects from an OBS parallel file system to its mount directory in the local file system, so that you can copy, modify, rename, or truncate objects locally. Parallel file systems provide more powerful file semantics and allow you to directly operate remote files.

Constraints

• The local directory used as the mount point does not need to be empty. After the mount, any existing files in that directory will become temporarily unavailable. However, those files will reappear after the unmount. You are advised to use an empty directory as the mount point.
• If obsfs is used to mount a parallel file system, bucket policies and IAM policies configured for the parallel file system take effect, but those configured for directories do not take effect.

Applicable Operating Systems

obsfs is compatible with Linux. An installation package can be downloaded directly, or you can compile it from the source code. For details, see Table 1.

To better support concurrent access, you are advised to use the latest version of obsfs, either by installing it or upgrading your current version. For details about how to obtain the latest version, see Table 1.
