Recovering from Insufficient File System Space Errors

To recover from insufficient file system space errors, do the following:

• Create more file system space.
  1. Run the df command to check for free space on all file systems.

     The following example displays free space on /dev/hd3:

     df -I /dev/hd3

  2. If the df command shows that a file system is out of space, back up and remove files as necessary to correct the problem. The following are files you may want to erase:
     • The /smit.log, /smit.script, and /.sh files

       The smit.log file contains detailed information of your SMIT sessions. The smit.script file contains task commands run by SMIT during your session with time stamps.

       Before removing these files, you may want to copy them to tape. To copy the SMIT files to streaming tape, enter:

       ls /smit.log /smit.script | backup -ivf /dev/rmt0

       To copy the SMIT files to 9-track tape, enter:

       ls /smit.log /smit.script | backup -ivf /dev/rmt0

     • Any unnecessary files in /tmp and /usr/tmp directories, such as printer log files and uucp log files

       The following example shows how to remove printer log files:

       rm -f /usr/adm/lp-log
        
       rm -f /usr/adm/lv-log

       The following example shows how to remove uucp log files:

       rm -f /usr/spool/uucp/LOGFILE
        
       rm -f /usr/spool/uucp/SYSLOG
        
       rm -f /usr/spool/uucp/ERRLOG

     • The core file, if it is very large, and old backup files

       The following example removes all *.bak,.*.bak, a.out, core, *, or ed.hup files:

       find / ( -name "*.bak" -o -name core -o -name a.out -o -name "...*" -o -name ".*.bak" -o -name ed.hup ) -atime +1 -mtime +1 -type f -print | xargs -e rm -f

     • Unnecessary lines or old date change records in the /var/adm/wtmp file

       The wtmp file is a binary file. To edit it, you must convert it to ASCII as follows:

       /usr/sbin/acct/fwtmp < /var/adm/wtmp > wtmp.new

       Edit the wtmp.new file with a text editor and convert it back to binary as follows:

       /usr/sbin/acct/fwtmp -ic < wtmp.new > /var/adm/wtmp

• Increase the file system size.

  If it is not possible to delete files to create more space, you can increase the size of the file system. See "Managing File Systems" in the AIX Version 4.3 System Management Guide: Operating System and Devices for more information.
