Full Discussion: make sure HA server no difference contents
Operating Systems Solaris make sure HA server no difference contents Post 302294841 by otheus on Friday 6th of March 2009 03:22:19 AM

You can do something like this on each server
Code:
#  find / -type f -print | egrep -v "^/(tmp|var|proc|sys|dev)/" | xargs  sum  2>&1 | sort -k 3,4  >/tmp/sums-`hostname -s`.out

Then copy the files to the same machine and folder and do a diff.

You might find that some files in your system will vary no matter what. Thus, the grep command excludes directories likely to have such files. Here, I exclude all of /tmp and /var. However, you might actually want some /var directories included. Either do these dirs separately or create a longer grep expression which exclude those /var directories you do not want to compare.

It should be noted that the "sum" command produces very "weak" results. To be more certain, replace it with md5sum or some crc check.

undohash

dohash(8)						      System Manager's Manual							 dohash(8)

NAME

       dohash, undohash - Hashes or unhashes IMAP configuration directories

SYNOPSIS

       /usr/sbin/dohash [-f] [-h] [-i]

       /usr/sbin/undohash

OPTIONS

       The  following  options	are  available	only for the dohash command: Forces the hashing process to continue even if the command encounters
       errors.	Prints a usage message for the command.  Runs the hashing process interactively.

DESCRIPTION

       The dohash command converts the IMAP configuration directories from the format for older versions of the Cyrus IMAP4 Revision 1	server	to
       the new format for Version 1.6.1 or higher.

       Starting  with Version 1.6.1 of the server, the IMAP user files in the quota and user directories are stored in a through z subdirectories,
       sorted by the first character of each user name. This arrangement reduces the number of entries	in  a  given  directory  and  consequently
       increases  performance  and  scalability.   The	dohash command creates the a through z subdirectories and sorts the existing IMAP files as
       described; the undohash command reverses this process, in case you need to revert to a previous version of the server.

       You can optionally sort the users' directories in the IMAP mail spool in the same manner if you enable  the  hashimapspool  option  in  the
       /etc/imapd.conf file before invoking the dohash command. See imapd.conf(4) for more information.

       Note  that  you must be logged in as the imap user to use the dohash command; otherwise, the newly-created subdirectories will not have the
       proper ownership.

EXAMPLES

       The following example shows output from the dohash command: # /usr/sbin/dohash configuration directory /var/imap...  hashing user directory
       hashing quota directory done hashing

       In  this  example, the configuration directory is /var/imap; therefore, you could check that the dohash command has successfully hashed the
       directories by using the ls command as follows: # ls /var/imap/quota /var/imap/user /var/imap/quota: a  b  c  d	e  f  g  h  i  j  k  l	 m
       n  o  p  q  r  s  t  u	v  w  x  y  z

       /var/imap/user: a  b  c	d  e  f  g  h  i  j  k	l  m  n  o  p  q  r  s  t  u  v  w  x	y  z

       The slash () indicates line continuation.

FILES

       Configuration file for the IMAP server. Specifies the location of the IMAP configuration directory.
