Event, log, and statistic daemons do not start anymore

The event, log, and statistic daemons do not start anymore. Furthermore, when trying to move or delete files generated by these deamons in the directory /phion0 following error message gets displayed: 

Cannot remove file: read-only filesystem

Check the dmsg entries with the command dmesg first:

    dmesg

Messages like the ones below indicate that the journal file is corrupt.

journal_bmap: journal block not found at offset 6156 on ide0(3,5)
Aborting journal on device ide0(3,5).
ext3_abort called.
EXT3-fs abort (device ide0(3,5)): ext3_journal_start: Detected aborted journal
Remounting filesystem read-only

Delete the corrupt journal file and create a new one. Follow the instruction below to create a new file. Enter following commands on the command line:

    phionctrl shutdown
    killall syslogd
    killall pre_syslogd
    killall metronom
    killall ntpd
    killall crond
    umount /dev/hda5
    e2fsck -y /dev/hda5
    tune2fs -O ^has_journal /dev/hda5
    tune2fs -j /dev/hda5
    reboot

Note:
In this example we use device "hda5". On other installations, the device could be another one.
