How to delete zero(0) size files in /var/spool/mqueue
Hi
I have lots of files in /var/spool/mqueue, as shown below:

They are filling up /var, as its now at 100%
I was thing in using "rm", but I am not sure that is the right option

Re: How to delete zero(0) size files in /var/spool/mqueue
Hi
I have managed to reduced it up to 83%, but I beleive if I clean /var/spool/mqueue, it will decrease a bit further.
#bdf /var Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol10 4718592 3929696 788896 83% /var mcelbill[356]/var #du -sk * 32 X11 1270384 adm 376 dt 0 empty 0 home 22368 jail 0 lost+found 8 mail 61376 microcode 8 net-snmp 0 news 1775720 opt 415600 preserve 24 run 1168 sam 289504 spool 16 statmon 48872 stm 4328 tmp 8 tombstones 0 uucp 1760 vx 96 yp mcelbill[357]/var #uname -a HP-UX mcelbill B.11.23 U ia64 2945220947 unlimited-user license
"/var/adm" is also big, but "sw" directory has data that I cannot remove, the same applies for "/var/opt"

Well, other than the fact that you need to remove all of the tuples, it's fine.
I had a previous post on removing mass quantities and lo and behold, you had the same question before!

Re: How to delete zero(0) size files in /var/spool/mqueue
Here's a better way to look at filesystem space:
# du -kx /var | sort -rn | head -20
4267800 /var 1997600 /var/tmp 1701992 /var/adm 1654320 /var/adm/sw 1249528 /var/adm/sw/save 729704 /var/tmp/labsystems 489072 /var/tmp/blh 395448 /var/tmp/labsystems/Dallas 384344 /var/adm/sw/save/PHCO_41439 354376 /var/opt 341896 /var/adm/sw/save/PHCO_41439/VXVM-RUN 301136 /var/tmp/labsystems/Dallas/OAT 270488 /var/tmp/blh/Git-1123 220232 /var/tmp/labsystems/Atlanta 218576 /var/tmp/blh/git-11.23 179120 /var/adm/sw/products 171088 /var/adm/sw/save/PHCO_41439/VXVM-RUN/etc/vx 171088 /var/adm/sw/save/PHCO_41439/VXVM-RUN/etc 168944 /var/stm 154800 /var/stm/logs
In this format, the largest directories and subdirectories are sorted to the top. In this example, /var/adm/crash has an old crash dump that can be removed, about 490 MB. /var/tmp/gcc has already been installed, so that directory can also be removed returning 331 MB of space.
/var/tmp doesn't show any large subdirectories, so there must be a lot of files that can be removed.
To sort the files inside a directory, use:
# ll /var/tmp | sort -rnk5 | head -20 -rw-r--r-- 1 root sys 200000000 Feb 21 14:32 big200 -rw-r--r-- 1 root sys 100000000 Nov 13 2013 big100 -rw------- 1 root sys 45086720 Jan 25 2013 HP-UX_11i_v2_Event... -rw------- 1 root sys 33679360 May 6 11:40 ixGnuPG_ixGnuPG_... -rw------- 1 root sys 16527360 Apr 16 15:59 openssl.depot -rw-r--r-- 1 root sys 13407209 Apr 25 12:25 ctmAAAa15402 -rw-r--r-- 1 root sys 4191370 Apr 25 12:11 ctmAAAa15033 -rw-r--r-- 1 root sys 389120 Jul 2 11:22 11.11-Iether.tar -rw-r--r-- 1 root sys 350459 Feb 10 06:05 atl1-crashcollector.tgz -rw-r--r-- 1 root sys 57450 Mar 17 10:20 imgr.tusc drwxrwxrwt 37 root root 49152 Jul 14 08:41 . -rw------- 1 root sys 30720 Oct 30 2012 dplookresult.tar -rw-r--r-- 1 root sys 16111 Jul 10 14:54 swagent.log drwxr-xr-x 10 root sys 8192 May 30 09:27 labsystems drwxr-xr-x 5 root sys 8192 May 21 07:52 tztab drwxr-xr-x 4 pwallek sys 8192 Dec 16 2013 pw drwxr-xr-x 3 root sys 8192 Oct 24 2013 bootdata drwxr-xr-x 2 root sys 8192 Dec 23 2013 drupalBuild drwxr-xr-x 2 pwallek sys 8192 Sep 19 2012 pw1 drwx------ 4 root sys 8192 Oct 14 2013 blh
So there are two very large test files that I forgot to remove, big200 and big100. And also several depots that have already been installed, so these can be removed.
In your example, /var/opt needs to be expanded to see the largest subdirectories, something like this:
# du -kx /var/opt | sort -rn | head -20
Also, read the man page for 'cleanup' and use it to properly trim the old, superceded patches in /var/tmp/sw.
And so on...
The zero length files occupy directory entries but no space so unless there were thousands of them, that isn't where the file removal needs to take place.

Re: How to delete zero(0) size files in /var/spool/mqueue
I did use a script that you provided, sometime back:
#!/bin/sh mailq | awk 'substr($0,1,1) !~ "[\t -]" { print $1 }' | while read i; do rm /var/spool/mqueue/?f$i done
but this only works for non-zero length size files

Re: How to delete zero(0) size files in /var/spool/mqueue
Hi
using "du" in /var/opt, resulted in:
du -kx /var/opt | sort -rn | head -20 1775720 /var/opt 914032 /var/opt/OV 909768 /var/opt/OV/tmp 520248 /var/opt/omni 520168 /var/opt/omni/log 127712 /var/opt/ignite 127216 /var/opt/ignite/recovery 127168 /var/opt/ignite/recovery/2010-11-23,11:13 91936 /var/opt/perf 91288 /var/opt/perf/datafiles 63928 /var/opt/sfmdb/pgsql 63928 /var/opt/sfmdb 44376 /var/opt/wbem 32768 /var/opt/sfmdb/pgsql/pg_xlog 30168 /var/opt/wbem/repository 28944 /var/opt/sfmdb/pgsql/base 19664 /var/opt/wbem/repository/root#cimv2 19104 /var/opt/wbem/repository/root#cimv2/classes 13520 /var/opt/sfmdb/pgsql/base/17142 9632 /var/opt/dce
I beleive nothing much I can do here, but, using the "cleanup" command:
cleanup -p -c 1 ### Cleanup program started at 07/14/14 16:26:35 Preview mode enabled. No modifications will be made. Commit patches superseded at least 1 time(s) on 'mcelbill'. Obtaining superseded patch information...done. The following patches superseded at least 1 time(s) can be committed: Superseded # Times Superseded Disk Space in /var/adm/sw/save Superseded By ========== ================== ============================== ============= PHCO_31601 1 745472 bytes PHCO_32426 PHKL_33494 1 401408 bytes PHKL_33820 PHKL_33495 1 81920 bytes PHKL_33562 PHKL_33552 1 352256 bytes PHKL_33563 PHKL_33607 1 106496 bytes PHKL_33731 All information has been logged to /var/adm/cleanup.log. ### Cleanup program completed at 07/14/14 16:26:35
So , can I go ahead in clean these patchs

Re: How to delete zero(0) size files in /var/spool/mqueue
These are prime candidates since they are the largest directories that look like logs and/or temporary files.
909768 /var/opt/OV/tmp 520168 /var/opt/omni/log
For the /var/opt/OV/tmp directory, are you running Network Node Manager (NNM)? If so, have yout network admin cleanup the log files - there's 900 MB of files that need to be cleaned up.
For /var/opt/omni/log, your Data Protector admin needs to reduce the logs.
In both cases, you'll probably find very old files there that should have been removed.
/var ALWAYS needs regular maintenance as it will always grow larger.
