I have a Solaris 7 box. We got a strange error in the syslog, which read as follows:
I consulted with a fellow sysadmin, and he suggested running "fsck -N" on the filesystem in question without unmounting it. So I did, and got a bunch of errors that read as follows:
these are just examples. Should I worry about these? I'm thinking that mounted file system with active processes would always be "dirty". But I'm not sure that I'm even supposed to run fsck on a mounted file system, even with -N option. Is -N option save or am I doing some kind of a damage?

fsck
FSCK(1) General Commands Manual FSCK(1)NAME
fsck, fsck1 - perform file system consistency check
SYNOPSIS
fsck [-aclmrs] [device] ...
OPTIONS -a Automatically repair inconsistencies
-c Check and list only the specified i-nodes
-l List the files and directories in the filesytem
-r Prompt user for repairs if inconsistencies are found
-s List the superblock of the file system
EXAMPLES
fsck /dev/hd4 # Check file system on /dev/hd4
fsck -a /dev/at0 # Automatically fix errors on /dev/at0
fsck -l /dev/fd0 # List the contents of /dev/fd0
fsck -c 2 3 /dev/hd3
# Check and list /dev/hd3 i-nodes 2 & 3
DESCRIPTION
Fsck performs consistency checks on the file systems which reside on the specified devices. Fsck1 is an alternate version for use on obso-
lete V1 file systems. When either the -a or -r flags are given, the file system will be repaired if errors are found. Before running fsck
on a mounted file system, it must first be unmounted. Trying to repair a mounted file system is dangerous and should not be attempted.
To repair the root file system (which cannot be unmounted), first type CTRL-F9 at the console to kill any and all processes. Log back in
as root, type sync to force any buffered changes to disk, run fsck on the root file system and immediately reboot the computer by typing
reboot.
It is necessary to kill all processes before repairing the root file system to prevent them from modifying any disk blocks while fsck is
running. This is only necessary for the root file system, any other file system can simply be unmounted before it is checked.
