Not a good idea...Unless you like fighting with funky issues....
That said in there (/var/adm/sw) you will find all the patches installed (and obsoleted, and uninstalled etc...) You may gain space by intellingently doing some cleanup, beware of the risk of not being able to "rollback" removed patches afterward... but very first superseeded patchs are of little risk...
What about /var/adm/syslog? what size are the logs there?
I trim them regularly ( customized by me though - important info in beginning syslog (at boot time) is always kept till next reboot...)
...
There are logs in /var/stm you can clean also and save 10-400 MB...
I have an old 10.20 that makes me sweat regularly (vital old legacy stuff nobody wanted to port : forms 3 with oracle 7.2.3...)
I only have this unique volume group vg00 in mirror on old SCSI 9GB (all space saving is important...) with all on it.
When I forget to look (thanks for reminding me Hehe...) the system crashes... and this box is not on site but in the countryside (with snow lately and Im on motorcycle...)
I just zero activity_log periodically, So Do it today:
Look at how fast its growing though:
approx 12k/min

Can anyone tell me how would I troubleshoot when /var becomes full with inodes? This is on HP11.11 system. Where used is 92%, ifree is 1891 iuse is 88%. Thanks. (3 Replies)
Hi Everyone,
I think I've filled up one of the partitions on my drive. I suspect that one of the applications I've been running has been spitting out junk files to this partition - most of which can be deleted. The problem is that I have no idea how to go look at what's on that partition and... (2 Replies)

I am currently running DesktopBSD as a live-CD and need to have a large /var partition because it is currently too small. I have a USB stick which is BSD formatted, and would like to have the /var partition moved over to it. How can this be done? Could I for instance use a symlink? (1 Reply)
hi, im new in aix administration.. months ago, I received mails, everytime a cron was executed. but now, I don't receive these mails.. and the /var/spool/squeue, gets full frequently. i'd like to know more information about this, what can i do?? sendmail is up, because, I executed ps -ef |grep...

This is my first time working with ZFS on Solaris 10. I am trying to set up /var in a separate partition from /.
During the installation, I came across the ZFS settings where I selected disks 0 and 1 to be mirrored with ZFS. Next was the option to have /var and / on separate datasets.
Is... (3 Replies)

Hi,
I have Solaris-10 (having multiple non global zones running on it). Its /var is getting full to 100% and I can see, there are files getting added to /var/audit. There are large in number, so even if I clearing them, it is filling /var. In past 24 hours, there are 53000 files are added. I am... (1 Reply)

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
