Sorry for that, got you confused too

Well, here's the requirement from the end user

1. to keep (certain system logs i.e-secure, messages, audit) logs for a period of 6 months (24 weeks)

Here's how I was planning on doing it

1. Rotate the logs for 24 weeks on weekly basis before removing them
2. But not before compressing the old logs weekly
So my logs would look like this

Code:
-rw------- 1 root root  1619422 Dec 5 04:02 messages.1.gz
-rw------- 1 root root 14822696 Dec 12 04:02 messages.2.gz
-rw------- 1 root root 15021180 Dec 19 04:02 messages.3.gz
-rw------- 1 root root 20300421 Dec 26 04:02 messages.4.gz
-rw------- 1 root root 13564183 Jan  2 11:52 messages.5.gz
-rw------- 1 root root 13564183 Jan  5 11:52 messages---------current log

The other way I was planning is it to rotate it on monthly basis:

1. Rotate the logs each month for 6 months before removing them
2. But not before compressing the old logs monthly

Code:
-rw------- 1 root root  1619422 Dec 2 04:02 messages.1.gz
-rw------- 1 root root 14822696 Jan 2 04:02 messages.2.gz
-rw------- 1 root root 15021180 Feb 2 04:02 messages.3.gz
-rw------- 1 root root 20300421 Mar 2 04:02 messages.4.gz
-rw------- 1 root root 13564183 Jan  2 11:52 messages.5.gz
-rw------- 1 root root 13564183 Jan  5 11:52 messages---------current log

Also I have about 4G of space on /var and if disk space is exhausted I can just add in another disk.

I know this will totally consume /var but they're really fussy about the logs so I have no choice but to keep them, however I can definitely housekeep these files if they grow too large and recall later from backup tapes..hope this is clear enough for your understanding Smilie

pmvarrun(8)							     pam_mount							       pmvarrun(8)

Name
       pmvarrun - updates /var/run/pam_mount/user

Syntax
       pmvarrun -u user [options]

Description
       A  separate  program is needed so that /var/run/pam_mount/user may be created with a pam_mount-specific security context (otherwise SELinux
       policy will conflict with gdm, which also creates file in /var/run).

       pmvarrun is flexible and can run in a number of different security setups:

   root-root
       When pmvarrun is invoked as root, /var/run/pam_mount's permission settings can be as strict as needed; usually (0755,root,root) is  a  good
       pick  as  it  gives  users the debug control over their refcount. Refcount files are given their respective owners (chowned to the user who
       logs in).

   user-user
       When invoked as the user who logs in, /var/run/pam_mount needs appropriate permissions to create a file, which means the write bit must	be
       set. It is also highly suggested to set the sticky bit in this case, so other users do not tamper with your refcount.

   root-user
       Some  programs or login helpers incorrectly call the PAM stack in a way that the login phase is done as root and the logout phase as a nor-
       mal user.  Nevertheless, pmvarrun supports this, and the same permissions as in root-root can be used. While the user may not  be  able	to
       unlink his file from /var/run/pam_mount, it will be truncated to indicate the same state.

Options
       --help, -h
	      Display help.

       --user user, -u user
	      User to handle, must be a valid username.

       --operation number, -o number
	      Increase volume count by number.

       -d     Turn on debugging.

Files
       /var/run/pam_mount/user
