ossfs

Support OS

• CentOS 7, 8
• Ubuntu 14, 16, 18, 20, 22

Limits

 * does not support hard links
 * not suitable for scenarios that require highly concurrent read and write operations
 * If a bucket is mounted to multiple clients and data is simultaneously written to the mount points,
   ossfs does not guarantee consistency.
 * If you do not add the mime.types file,
    OSS sets Content-Type of the uploaded object to application/octet-stream by default.

 * upload to a bucket may initiate two upload requests
    The first request creates a 0-byte object and
    the second request uploads actual data to create the object in the bucket.
