Using VxFS as a shared file system
VxFS is also supported as "namefs" in the WPAR, so a VxFS file system can also be shared between the global environment and WPARs.
To use VxFS as a shared file system
- Mount vxfs on some directory in the global environment.
# mount -V vxfs /dev/vx/dsk/testdg/vol1 /mnt
- Mount that directory in /wpar/ wpar1/vxfs_dir.
# mount /mnt /wpars/wpar1/vxfs_dir/
- Start the WPAR.
# startwpar -Dv wpar1 2>/wpar1_tl2
- Login to the WPAR.
# clogin wpar1
- After login to wpar1, /vxfs_dir will appear as namefs.
