Description Tky 2014-02-13 12:00:02 UTC 
hi,
i have install xfsprogs to ports with make.
when I try to mount the secondary partition with XFS FS, I get errors ..
I have read that has been removed from the kernel XFS support.
You get a patch or implementation to mount it read-only?

# file - < /dev/ada1s1
/dev/stdin: SGI XFS filesystem data (blksz 4096, inosz 256, v2 dirs)

# mount -r -t xfs /dev/ada1s1 /mnt/store/
mount: /dev/ada1s1: Operation not supported by device

# make search name=xfsprogs
Port:   xfsprogs-2.9.8

The XFS support was removed from stable/10 (then head) in r247631, as part of the MPSAFE-VFS project.  The XFS kernel code was not safe to operate without the VFS layer automatically grabbing the Giant kernel lock.  The compat code in the VFS to automatically grab the Giant lock was removed to further general improvements to the VFS layer, and will not be reintroduced.  Even read-only support would require substantial work, and I do not expect that it will be forthcoming.
