GCSFuse function not implemented errors

[ashmeenkaur]

I recently encountered an error with GCSFuse: "fuse: *fuseops.FallocateOp error: function not implemented." Is this expected behavior? Additionally, are there any other functions that GCSFuse doesn't currently support?

Yes, this is expected behavior. Currently, GCSFuse does not support the following operations:

• Fallocate: Used for pre-allocating disk space for a file so that disk space does not run out before writing. This is usually not implemented for Cloud based FUSE products as the disk space running out is not a concern there.
• SetXattr, ListXattr, GetAattr, RemoveXattr: GCSFuse doesn't support extended-attributes (x-attrs) operations. Extended attributes provide a way to associate additional metadata or information with files and directories beyond the standard attributes like file size, modification time, etc. This is not usually implemented for Cloud based Fuse products.
• CreateLink: Creates a hard link (a directory entry that associates a name with a file). GCSFuse doesn't support hardlinks.
