Howto extend a ext3 filesystem in RHEL5

In RHEL5 ext2online is no longer available. However, do not despair – you can still grow your ext3 filesystems while online: The functionality has been included in resize2fs so to resize a logical volume, start by extending the volume:

# lvextend -L +2G /dev/systemvg/homelv

And the resize the filesystem:

# resize2fs /dev/systemvg/homelv (by omitting the size argument resize2fs defaults to using the available space in the partition/lv)
