The LV and filesystem are different things, although obviously related. You
also have to extend the filesystem, using the chfs command.
You can use just chfs, (no extendlv), and it will automatically extend the
LV. However you have very little control over where the partitions are
allocate, (no way to use a map file). If you need to reset maximum LPs or
upper bound, it'll fail the same as extendlv would.
Because I do this fairly often, I have a little script which re-sets the
size of a JFS to the size of its LV:
#!/bin/ksh
#
# Increase the size of a filesystem to that of its logical volume.
#
Filesystem=$1
lsfs -q $Filesystem |tail -1|awk {'print $3 $6'} | tr ',' ' ' |read LV_Size
FS_Size
if [ $LV_Size -ne $FS_Size ]
then
chfs -a size=$LV_Size $Filesystem
else
echo Filesystem already uses all of Logical Volume.

Hi all,
I increased the number of logical partitions allowed to a logical volume,
but changes are not reflected in the file system. The AIX doc mentionne that
I should use chlv command to modify the caracteristics of the file system.
OK, but how can I recuperate the partitions allowed to the lv ?
