Use e2fsadm command to grow or extend a partition on LVM. Use vgdisplay command to display info about LVM.
To increase /data by 5000Mb type command
Code:
# umount /data
# vgdisplay
# e2fsadm -L+5000M /dev/vg0/data
# vgdisplay
Your own /oracle example:
Code:
# umount /oracle
# vgdisplay
# e2fsadm -L+5000M /dev/VG01/lvoracle
# vgdisplay
Read man pages of e2fsadm for more info. Hope this helps! If you are doing this first time, try it in a sandbox before production box.
