Using a VxFS file system within a single system WPAR
The following procedure describes how to set up a WPAR with VxFS for non-root partition.
To set up WPAR with VxFS for non-root partition
- Create a vxfs filesystem in the global environment:
# /opt/VRTS/bin/mkfs -V vxfs /dev/vx/rdsk/testvg/vol1
- Create a WPAR. For example, use the following command.
# mkwpar -n wpar1
For other options while creating WPARs, refer to the IBM Redbook for WPAR.
- List the WPAR.
# lswpar Name State Type Hostname Directory -------------------------------------------------------------------- wpar1 D S wpar1 /wpars/wpar1
- The above output shows that WPAR does not have the devices. To get the vxfs file system in WPAR, create the file system in the global environment. Then mount it to the WPAR directories which are located at
/wpar/wparname/
# mkdir /wpars/wpar1/vxfs_dir # mount -V vxfs /dev/vx/dsk/testdg/vol1 \ /wpars/wpar1/vxfs_dir
- Start the WPAR:
# startwpar -Dv wpar1 2>/startwpar_tl2
- Log in to the WPAR.
# clogin hostname
For example, to log in to the WPAR wpar1:
# clogin wpar1
- The following output shows the VxFS mount point in the WPAR.
# mount
node mounted mounted over vfs date options ------ ------- ------------ ---- ------------ ------------- Global / jfs2 Jun 23 03:15 rw,log=INLINE Global /home jfs2 Jun 23 03:15 rw,log=INLINE Global /opt namefs Jun 23 03:15 ro Global /proc namefs Jun 23 03:15 rw Global /tmp jfs2 Jun 23 03:15 rw,log=INLINE Global /usr namefs Jun 23 03:15 ro Global /var jfs2 Jun 23 03:15 rw,log=INLINE Global /vxfs_dir vxfs Jun 23 03:14 rw,delaylog, suid,ioerror=mwdisable,qio,largefiles
- To stop the WPAR, use the following command:
# stopwpar -Dv wpar1 2>/wpar1_tl2
