Hi,
If inodes need to be 3-4 times greater than fd.file-max. Can you modify the current inode in the filesystem? Can you modify it on the fly? Or only in the creation of FS.
I'm using redhat ent 4.

Is there a simple way of calculating the max number in a set of variables, so
a=1
b=3
c=6
d=30
something that says
e=max($a, $b, $c, $d)
I've found a way to do it using:
a="1"
b="3"
c="5"
d="50"
if ;
then
t=$a

dumpe2fs
DUMPE2FS(8) System Manager's Manual DUMPE2FS(8)
NAME
dumpe2fs - dump ext2/ext3/ext4 filesystem information
SYNOPSIS
dumpe2fs [ -bfghixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] device
DESCRIPTION
dumpe2fs prints the super block and blocks group information for the filesystem present on device.
Note: When used with a mounted filesystem, the printed information may be old or inconsistent.
OPTIONS
-b print the blocks which are reserved as bad in the filesystem.
-o superblock=superblock
use the block superblock when examining the filesystem. This option is not usually needed except by a filesystem wizard who is
examining the remains of a very badly corrupted filesystem.
-o blocksize=blocksize
use blocks of blocksize bytes when examining the filesystem. This option is not usually needed except by a filesystem wizard who is
examining the remains of a very badly corrupted filesystem.
-f force dumpe2fs to display a filesystem even though it may have some filesystem feature flags which dumpe2fs may not understand (and
which can cause some of dumpe2fs's display to be suspect).
-g display the group descriptor information in a machine readable colon-separated value format. The fields displayed are the group
number; the number of the first block in the group; the superblock location (or -1 if not present); the range of blocks used by the
group descriptors (or -1 if not present); the block bitmap location; the inode bitmap location; and the range of blocks used by the
inode table.
-h only display the superblock information and not any of the block group descriptor detail information.
-i display the filesystem data from an image file created by e2image, using device as the pathname to the image file.
-x print the detailed group information block numbers in hexadecimal format
-V print the version number of dumpe2fs and exit.
BUGS
You need to know the physical filesystem structure to understand the output.
