Automatic increase of maximum allocation value during resize of JFS2

During expansion of a file system the following error may occur:


# chfs -a size=+100G /myfs
0516-787 extendlv: Maximum allocation for logical volume myfs_lv
is 512.


In this case administrator must manually execute chlv -x <some value> myfs_lv and then expand the file system again. Most of the time it doesn't make any sense, just one more step to tell junior administrators, what they should do in case of the error.


Add automatic expansion of maximum allocation value during chfs operation. If administrator wants to expand the file system, (s)he wants to increase the maximum number of LPs in the logical volume too.
