The table in this appendix list the mount options that are supported by CXFS, depending upon the server platform. Some of these mount options affect only server behavior and are ignored by client-only nodes.
The tables also list those options that are not supported, especially where that support varies from one platform to another. The mount commands supports many additional options, but these options may be silently ignored by the clients, or cause the mount to fail and should be avoided. For more information, see the mount(8) man page.
 | Note: The following are mandatory, internal CXFS mount options that
cannot be modified and are set by clconfd and
cxfs_client:
|
The table uses the following abbreviations:
| Y = Yes, client checks for the option and sets flag/fields for the metadata server |
| N = No, client does not check for the option |
| S = Supported |
| n = Not supported |
| D = Determined by the CXFS administration tools (not user-configurable) |
A blank space within the table means that the option has not been verified.
The Linux architectures are (as output by uname -i) 64-bit Linux on x86_64 and ia64 architectures.

[a] Do not use the dmi and filestreams options together. DMF is not able to arrange file extents on disk in a contiguous fashion when restoring offline files. This means that a DMF-managed filesystem most likely will not maintain the file layouts or performance characteristics normally associated with filesystems using the filestreams mount option. | ||||||||
