/home file system full

    Model:              9000/800/rp3440

    Main Memory:        6142 MB

    Processors:         2

    OS mode:            64 bit            

B.11.11

/dev/vg00/lvol4    1048576   55600  985240    5% /home

 

  • The /home file system normal size is 5% used.
  • There are some big startlog under the user's .dt folder.
  • There are also some core files
  • Despite the startlog are zeroed and the core removed, the %used is 70%.
  • du . -k | sort -n shows no other big files under /home
  • all the applications are stopped but the size is the same.
  • Once the server is rebooted, the file system gets its original size (5%)
  • It seems that there is some process using the file system resources.
  • The situation repeats every 11 days aprox.
  • top shows a lot of dtfiles processes on top running (see below)
  • the fuser -u /home command shows the most common process running: /bin/csh -c unsetenv _ PWD (44) ; /usr/bin/ksh /usr/dt/bin/Xsession (42) ; /usr/dt/bin/dtsession (42) ; dtfile -noview (40) ; dtwm (42).
  • Attached there is a spreadsheet with the list of process fuser -u /home before the reboot.

Is it possible to easily identify the process that is causing the file system gets full?

 

Thanks and reagards,

 

Juan.

>top shows a lot of dtfiles processes on top running

 

There must be one process that that's still running.  It may be dtfiles.

Right.  The right tool is lsof, not fuser.
