I would like to know if it is possible to mount an XFS filesystem on a Mac as I want to use XFS on my flash drive.
From author's website:
Fuse-xfs is a MacFuse (OSXFUSE) driver for XFS filesystems. This driver allows Mac OS 10.7 with OSXFUSE/MacFuse to mount XFS filesystems in read only mode.
The journal is ignored, but basic read only operations should work fine.
This software should be considered alpha, and provides no guarantees that the XFS filesystem remains unaltered (although the code does not support writing in any way). Use of the software is entirely at the users own risk.
A complicated solution would be to use a virtual machine like VirtualBox run a linux in that and use it to do your filesystem operations.
Unfortunately I couldn't find a recent documentation that states whether you need administrator privileges for the install.
