The easiest and fastest solution IF there is nothing yet on /data2 is to turn it into /data.

# umount /data2
Next step needed if /data directory (read mount point) does not exist.
# mkdir /data
# cp /etc/vfstab /etc/vfstab.10082006
# vi /etc/vfstab
Change /data2 to /data and save file
# mount /data
Done. Unmount /data2, make sure /data mount point is available, copy /etc/vfstab to file name of your choice (just in case), change /etc/vfstab to have d38 mount as /data instead of /data2, save changes, and mount /data.

hi RTM,

Thank you for your advice

Best Regards,
