Help growing fs
Hello,

I have a filesystem that I'm trying to grow but it's giving me the error:

Code:
0516-404 allocp: This system cannot fulfill the allocation request.
        There are not enough free partitions or not enough physical volumes
        to keep strictness and satisfy allocation requests.  The command
        should be retried with different allocation characteristics.

I'm missing something but don't know enough about AIX filesystems to know what it is. The command lsvg mvg shows the following:

Code:
VOLUME GROUP:       myvg                    VG IDENTIFIER:  00f6757600004c000000013f3e5e8f1f

And the output of lslv mylv:

STALE PPs:          0                      BB POLICY:      relocatable

MOUNT POINT:        /fs                   LABEL:          /fs

Serialize IO ?:     NO
INFINITE RETRY:     no
DEVICESUBTYPE:      DS_LVZ
COPY 1 MIRROR POOL: None

COPY 3 MIRROR POOL: None

I think "PP SIZE" is the problem, but I'm not 100% sure. How can I increase the fs without taking the system offline?

pydf

PYDF(1) 						      General Commands Manual							   PYDF(1)

NAME

       pydf - report colourised filesystem disk space usage

SYNOPSIS

       pydf [options] [file]

DESCRIPTION

       pydf  is a python script that displays the amount of disk space available on the mounted filesystems, using different colours for different
       types of filesystems. Output format is completely customizable.

       If an optional
	      file argument is given, pydf displays just information about filesystem containing the file(s), otherwise  it  displays  information
	      about all mounted filesystems.

OPTIONS

       --help Show summary of options.

       -v, --version
	      Show version of program.

       -a, --all
	      include filesystems having 0 blocks

       -h, --human-readable
	      print sizes in human readable format (e.g., 133K 2341M 2448G)

       -H, --si
	      likewise, but use powers of 1000 not 1024

       --block-size=SIZE
	      use SIZE-byte blocks

       -k, --kilobytes
	      like --block-size=1024

       -i, --inodes
	      show information about inodes instead of blocks

       -l, --local
	      limit listing to local filesystems

       -m, --megabytes
	      like --block-size=1048576

       -g, --gigabytes
	      like --block-size=1073741824

       --blocks
	      use filesystem native block size

       --bw   do not use colours

       --mounts=FILE
	      file  to	get  mount  information  from.	 On normal linux system, only /etc/mtab or /proc/mounts make sense.  Use /proc/mounts when
	      /etc/mtab is corrupted or inaccessible (the output looks a bit weird in this case though)

       -B, --show-binds
	      Show also mount --bind mounted filesystems.

BUGS

       When running with python3, mountpoints with out-of-locale non ASCII names will not be displayed (due to	inability  of  os.statvfs  to  use
       bytes instead of strings).

FILES

       /etc/pydfrc
	      main configuration file

       ~/.pydfrc
	      per-user configuration file
