I'm currently in the process of adding to our AFS cell, we have some new
RS6K E-30's with 4 18.2GB drives.  When creating the VG's we had set our
PPs to 32MB.

Here is the configuration via the lsvg command:

# lsvg -l AFSvg2
AFSvg2:
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
loglv01             jfslog     1     1     1    open/syncd    N/A
lv02                jfs        540   540   1    open/syncd    /vicepc
# lsvg AFSvg2
VOLUME GROUP:   AFSvg2                   VG IDENTIFIER:  0035804a82ad3d0c
VG STATE:       active                   PP SIZE:        32 megabyte(s)
VG PERMISSION:  read/write               TOTAL PPs:      542 (17344 megabytes)
MAX LVs:        256                      FREE PPs:       1 (32 megabytes)
LVs:            2                        USED PPs:       541 (17312 megabytes)
OPEN LVs:       2                        QUORUM:         2
TOTAL PVs:      1                        VG DESCRIPTORS: 2
STALE PVs:      0                        STALE PPs       0
ACTIVE PVs:     1                        AUTO ON:        yes


My main question is this, when creating the File system, in this example
/vicepc, what are the best values to set in the following fields in SMIT: 

Fragment Size (bytes)                               4096                +
Number of bytes per inode                           4096                +
Allocation Group Size (MBytes)                      8                   +

Second, would it be better to create the logical volumes first, then
create the File System (which can create the lv's automatically if they
don't exist).  And if so, what would be some recommended values.

Thanks
