FAQs

Can I Mount a Parallel File System to Multiple Clients at the Same Time?

Yes.

Can a Single Client Have Multiple Parallel File Systems Mounted at the Same Time?

Yes. Each mount process is independent. You can run the mount command multiple times to mount multiple file systems or buckets.

After I Use obsfs to Mount My Parallel File System to an ECS, Is the Traffic Consumed by My File System Measured as OBS Traffic or ECS Traffic?

Accessing the ECS from your mounted file system will generate both OBS traffic and traffic of the ECS elastic network interface. If OBS is accessed from a public network, traffic of elastic IP address (EIP) bound to the ECS is also generated.

Traffic of the ECS elastic network interface is free. For details about OBS billing, see OBS Billing Overview. For details about EIP billing, see EIP Billing Overview.

How Can Other Users Access a Mounted Parallel File System?

Generally, only the user who mounted the parallel file system has access.

To authorize other users the access to the mount directory, you can specify the allow_other parameter in the mount command, for example:

./obsfs filesystem001 /mnt/mount_path/ -o url=http://obs.ap-southeast-1.myhuaweicloud.com  -o passwd_file=/etc/passwd-obsfs -o big_writes -o max_write=131072 -o allow_other -o use_ino

What If the libfuse or OpenSSL Version in My Runtime Environment Doesn't Meet Requirements?

• obsfs supports libfuse 2.9.7, 2.9.8, or 2.9.9. If your system has a different libfuse version installed, remove it and install the correct version by referring to libfuse Installation Guide.
• To check the libfuse version, use the system's built-in version query command or run the following command to locate libfuse.so:

  find / -name libfuse.so*

• obsfs supports only OpenSSL 1.0.0 and earlier. If your development environment does not have OpenSSL 1.0.0 or an earlier version, use the method in Method 2: Generating obsfs by Compilation.
