FIEMAP isn't currently supported on ZFS-based OSDs, so I suspect this test is just skipped for ZFS on the orion branch.

However, it also is bad that users can trigger an LASSERT() on the server, so that needs to be fixed first. Instead of LASSERT() it should just be returning -EOPNOTSUPP, as the regular ioctl does if this ioctl is unsupported on the underlying filesystem.

Was this test run with LDiskFS or ZFS OSTs?

[Minh Diep]
