i-nodes
first off, i am new to unix so please bear with me. i was reading somewhere that if your i-nodes get critical that it can slow your network down. what are i-nodes and when do they become a critical number? this is what mine states:
/ (/dev/root ): 777058 blocks 569290 i-nodes
/stand (/dev/boot ): 103032 blocks 15984 i-nodes
/USR2 (/dev/USR2 ): 890848 blocks 511359 i-nodes
/USR4 (/dev/USR4 ): 2115138 blocks 275448 i-nodes
/USR3 (/dev/usr3 ): 1675780 blocks 508950 i-nodes
/USR5 (/dev/USR5 ): 737674 blocks 517652 i-nodes
thanks

debugreiserfs
DEBUGREISERFS(8) System Manager's Manual DEBUGREISERFS(8)
NAME
debugreiserfs
SYNOPSIS
debugreiserfs [ -dDJmoqpS ] [ -j device ] [ -B blocknumber ]
device
DESCRIPTION
It helps sometimes to solve problems with reiserfs filesystems. Being called w/o options it prints super block of reiserfs filesystem found
on the device.
device is the special file corresponding to the device (e.g /dev/hdXX for IDE disk partition or /dev/sdXX for SCSI disk partition).
OPTIONS
-j device
print contents of journal. Also with the option -p it allows to pack journal into archive with other metadata
-J print journal header.
-d print formatted nodes of the internal tree of the filesystem
-D print formatted nodes of all used blocks of the filesystem
-m print contents of bitmap (not very useful)
-o print objectid map (not very useful)
-1 blocknumber
print specified block of the filesystem
-p Makes debugreiserfs to find filesystem metadata This option exists to help reiserfsck debugging. If reiserfsck fails - you may
extract filesystem metadata with debugreiserfs -p /dev/xxx |gzip -c > xxx.gz. We download that data and make the filesystem similar
to your with gunzip -c xxx.gz | unpack /dev/xxx (unpack is included into reiserfsprogs package). This usually allows to reproduce
and debug the problem quickly. When data file is not too large.
-S When -S is not specified -p deals with blocks marked used in the filesystem bitmap. With this option set they will work with whole
device.
-q Suppress showing speed of progress when -p is in use
