Problems after filesystem housekeeping
I have noticed that after I clear up the /var filesystem, there are always problems.

Does deleting the OLDsyslog.log file cause problems like missing directories and problems accessing crontabs?

There were two situations where I faced problems.
1) Deleted OLDsyslog.log (Of course I created an archive of this before deleting).
The next day there were problems of missing directories in a path not even related to the log which is /var/adm/syslog.

2) In this situation, I also did the same - deleted old syslog, and backdated ones, and now there is another problem, whereby users are not able to access their crontab :

Code:
$ crontab -l
crontab: you are not authorized to use cron.  Sorry.
bscs.L28bi02> (/bscsbin/lisa)

And so I checked the server, and found that even the cron directory went missing! So this means that everything under cron like cron.allow was gone. I had to manually create the directory and this file for the user to be able to use it again.

Now the user can list the crontab entries, but not able to save new cron entries :
Code:
/var/tmp/aaaa15475" 277 lines, 14951 characters cron may not be running - call your system administrator

I restarted cron, then I can save the entries.

Also, I realize now that many directories in /var/adm are missing. Like /var/adm/sa, /var/adm/syslog.
I cannot even get any output from the command "last". (To check who deleted the files). The error is :

Code:
# last
 : No such file or directory

resize_lfs

RESIZE_LFS(8)						    BSD System Manager's Manual 					     RESIZE_LFS(8)

NAME

     resize_lfs -- resize a mounted log-structured filesystem

SYNOPSIS

     resize_lfs [-v] [-s new-size] mounted-file-system

DESCRIPTION

     resize_lfs grows or shrinks a mounted log-structured filesystem to the specified size.  mounted-file-system is the name of the filesystem to
     be resized, and new-size is the desired new filesystem size, in sectors.  If new-size is not specified, resize_lfs will default to the cur-
     rent size of the partition containing the filesystem in question.

     When growing, the partition must be large enough to contain a filesystem of the specified size; when shrinking, resize_lfs must first
     ``clean'' the segments that will be invalid when the filesystem is shrunk.  If this cleaning process results in these segments becoming
     redirtied, this indicates that the given new size is not large enough to contain the existing filesystem data, and resize_lfs will return an
     error.

EXAMPLES

     To resize the file system mounted at /home to 32576 sectors:
	   resize_lfs -s 32576 /home

SEE ALSO

     fsck_lfs(8), lfs_cleanerd(8), newfs_lfs(8)

HISTORY

     The resize_lfs command first appeared in NetBSD 3.0.

AUTHORS

     Konrad Schroder <perseant@NetBSD.org>

BUGS

     resize_lfs should be able to resize an unmounted filesystem as well.
