find /var -size -8k
  • You can check whether running or not , check it by using ps ax | grep crond
  • If it’s not running at start up, add it into /etc/rc.local then at it into /etc/init.d/crond start
  • edit your crontab using command crontab -e
  • list of your crontab using crontab -l
  • if you found unable to save because not enough disk space at your linux OS, then check it using df -i or df -h
  • find your below 8k files using find /var -size -8k , then delete it using find {trouble directory} -size -8  -exec rm -f {} ;

You can put your first time script crontab. Make sure your crontab daemon is already started. To start, type this /etc/init.d/crond start

Weird on fedora live cd

March 19th, 2009 No comments

Nyoba jalanin Fedora Core 10 di laptop compaq presario. USB kedetect, dan dengan lancarnya bisa booting sampe suatu ketika ada tulisan seperti itu

 [...]
    Loading vmlinuz0 .........
    Loading initrd0.img ........
    Ready
    Memory for crash kernel (0x0 to 0x0) notwithin permissible range
    pnp: PnPACPI: METHOD_NAME_CRS failure for PNP0c01
    udev[454]: add_to_rules: unknown key 'ATTRS{media}'

    #-- The "Memory for crash kernel ..." and the "udev[454]: add ..."
    #-- also appear during my laptop's boot; the "pnp: PnPACPI ..."
    #-- does NOT appear on any laptop which boots fine beyond this point.
    #-- Below is the remaining sequence for a desktop Live CD boot

    --------------------------------------
    WARNING: Cannot find root file system!
    --------------------------------------

    Create symlink /dev/root and then exit this shell to continue the
    boot sequence.

    bash: no job control in this shell
    bash-3.2#

dan kalo misalnya kita bikin symbolic link ke / hasilnya malah begini

    mount: special device /dev/root does not exist
    Bug in initramfs /init detected. Dropping to a shell. Good luck!

    bash: no job control in this shell
    bash-3.2#

akhirnya setelah lama ngutak ngatik di web, ternyata persoalan diatas diakibatkan adanya controller IDE / CDROM yang pake controller SATA. Jadi untuk harus ada init string yang diganti pada saat sebelum proses booting. Silahkan ganti root=UIDxxxxxxx dengan lokasi usbnya yang biasanya ada di /dev/sdb1. (ini ada di menu Grub).

Mudah – mudahan berhasil…kalo gw sih berhasil
