We are running 2.4.21-27.ELsmp redhat linux.
I have ext3 filesystems on this box and I have two logical volumes.
My task is to expand the filesystems. There is no online expanding package on this server. How do I find ... 1.If I have the space I am looking for? 2. What commands to expand the required filesystems

part of the 'mount' command gives...
/dev/VG01/lvoracle on /oracle type ext3 (rw)
/dev/VG01/lvora00 on /ora00 type ext3 (rw)
/dev/VG01/lvora01 on /ora01 type ext3 (rw)
/dev/VG01/lvora02 on /ora02 type ext3 (rw)
/dev/VG01/lvora03 on /ora03 type ext3 (rw)
/dev/VG01/lvora04 on /ora04 type ext3 (rw)

Any help with this is appreciated.

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.
