Subject: Partition full problem
Source: Personal experiments
Problem: How to find the directory or file filling up a hard drive
partition.
Solution:
1) If /opt partition is full, continue in multiuser mode.
If /root, /var or /usr partition is full, shutdown station
and continue in single user mode.
It is important that no stations are left 'rmounted'.
(Remember a WP51 always mounts its AW host)
2) Use the 'du' command to create a report file with the size of all
directories of the partition that is full.
Create report file in a partition different from the one that is full.
Suggested locations: /usr or /tmp (avoid /opt)
/usr has been used on examples below.
3) Sort lines in report by size, in reverse order.
4) Look for non-familiar names at the beginning of the list, or abnormal
size.
Typical culprits are:
- Core files
- Applications installed on wrong partition or directory
- Big files in /dev, because the real device was not present (printer, tape
drive, etc)
(Check: /dev/LPxx-nn, /dev/tape2, /dev/rst9, etc)
- Optical drives that are not mounted and working properly
(They are usually mounted in directory /both)
- Big log files in /var
Partitions Refresher:
AW/AP51 = /, /var, /usr, /opt
WP51 (v7.x) = /, /var, /usr, /opt
WP51 = /, /usr, /opt
AP20 = /, /tmp, /usr
Below are 3 examples, with samples of several station types.
1) /var partition (or /usr, or /opt) is full, on a 51 station
2) /root partition is full, on a 51 station
3) /root partition is full, on AP20
=================================================================
1) /var PARTITION IS FULL (51 station)
Use a similar procedure if /usr or /opt is full.
If /opt partition is full, remember you NEED to be in multiuser mode.
If /root partition is full, see example 2 and 3 below.
3AWE01# cd /var
3AWE01# du > /usr/list
File /usr/list has number of blocks used for each subdirectory under /var.
3AWE01# cd /usr
3AWE01# sort -n -r +0 list > list1
File /usr/list1 has directories under /var, sorted by size, in reverse order
3AWE01# more list1
24500 .
12624 ./adm
9394 ./adm/sa
9162 ./sadm
4186 ./sadm/install
3832 ./sadm/pkg
962 ./sadm/patch
928 ./tmp
516 ./lp
514 ./lp/logs
...
Identify the culprit directory from the list:
- It could be a non-familiar directory name
- Or a known directory with abnormal size, because it has big file(s)
- Known growing files:
/var/adm/wtmpx, utmpx; /var/tmp/online.log, /var/cron/log,
/var/mail/uucp,
Do not just delete those files, try instead:
wtmpx: Be sure there are no users; cd /var/adm ; cp /dev/null wtmpx
utmpx: Be sure there are no users; cd /var/adm ; cp /dev/null utmpx
online.log: cd /var/tmp ; tail -100 online.log > zzz ; ln zzz online.log
; rm zzz
uucp: crontab -r uucp ; echo " " > /var/cron/log ; rm
/var/mail/uucp
messages: cd /var/adm; tail -100 messages > zzz ; ln zzz messages ; rm
zzz
- It is always easier if you compare report against a list from a good box.
After you found the problem remember to remove report file:
3AWE01# cd /usr
3AWE01# rm list list1
=================================================================
2) ROOT PARTITION IS FULL (51 station)
The procedure is similar but need an additional last step, for AP20,PW:
- List all directories under root
- Sort resulting list by size, in reverse order
- REMOVE lines for other partitions (/var, /usr and /opt)
On Solaris, you can use "du -d" to list directories only from an
specific partition.
Remember to rumount any other station, and better if you can
take the station to SINGLE USER.
If not at single user, you might overlook any hidden files (see HH831).
This example is for an AW51B.
Example:
4AWB01# rmount
3AWE01: mounted on /rem/3AWE01
4AWB01# rumount 3AWE01
4AWB01# rmount
4AWB01# cd /
4AWB01# /usr/bin/du -d / > /usr/list
NOTE: The option "-d" is valid only for command "/usr/bin/du", on
Solaris.
(Be patient. It might take a few minutes)
(It might take FOREVER if you forgot to rumount remote stations!)
4AWB01# cd /usr
4AWB01# sort -n -r list > list1
4AWB01# more list1

678 ./platform/sun4u/kernel/drv
620 ./etc/lib
list1 has directories under root ONLY, and NOT from other partitions.
-----------------
If you didn't use option -d, list1 will have directories from ALL
partitions
and you will need to remove those extra lines. See below:
4AWB01# more list1

1041665 ./proc

193582 ./usr/openwin
160098 ./opt/fox/ami_space
94040 ./usr/openwin/lib
73710 ./usr/fox/ia16
...
Removing lines from other partitions:
4AWB01# egrep -v './var|./usr|./opt' list1 > list2
Result list2 will have only lines for /root
On 51F and 51G, use: egrep -v './var|./usr|./opt|./proc' list1 > list2
On WP51: egrep -v './opt|./usr' list1 > list2
NOTE: If you left rmounted the AW host of a WP51, you might want to
remove all lines that have: ./rem/AWLBUG
with: grep -v './rem/AWLBUG' list2 > list3

The du command's -s flag, e.g.
du -ks *
will show the total size of each directory on the current level only.
This is very convenient to work one's way down to the offending dir if
the files taking up space are scattered among several subdirectories.
