Hi,
This seems a Frequent problem we get it on HP-UX LVM too.
People do an lvextend and then wonder why the filesystem has not grown
to fill the lvol.
Perhaps a message like.
[root at ocalhost /root]# lvextend -l 256 /dev/vg01/lvol2
lvextend -- extending logical volume "/dev/vg01/lvol2" to 1 GB
lvextend -- doing automatic backup of volume group "vg01"
lvextend -- logical volume "/dev/vg01/lvol2" successfully extended
Note: You need to run a resize utility such as ext2resize before
the space is available in the file system.
[root at localhost /root]#
Or lvextend could check the mount table and offer to run ext2resize
for you. If that seems like a neat idea I would be willing to write
the code.
Regards,
Tom.
