    Question UNEXPECTED INCONSISTENCY: RUN fsck manually

    Dear SUSE Linux Expert,

    Can you help me boot my computer, I am receiving this error message on my screen UNEXPECTED INCONSISTENCY: RUN fsck manually

    fsck failed for at least one filesystem (not / y)
    Please repair manually and reboot.
    The root file system is already mounted read-write.

    I really have no idea what to do, please i need your help.

    the most common reason why you may have this error is that you MAY have ONE or several partitions / drives (USB ?) that are NOT connected to your booting machine but are listed in your /etc/fstab
    if a drive is missing you may manually delete that entry in your /etc/fstab (or connect missing drive)

    all partitions or drives listed in /etc/fstab are expected to be present/connected on boot, else you have this error
    some of the external drives have an ON/OFF switch
    make sure any external drive is ON and connected

    if you still have the same error
    then you have to do a manual file system check
    file system errors can occur when you lose power of just power OFF your machine while system is writing and data damage has occurred

    the use of fsck is easy you just have to know what exact file system you have = ext3/ext4 or ?

    If you have an external drive OFF or not connected (i.e. an USB disk), but you don't want to delete its entry in your /etc/fstab, you can edit your fstab file, so the system doesn't check this filesystem and doesn't hang up.


    You have this line in fstab, for the USB external disk:
    /dev/sdb1 /media/LINUX auto rw,nosuid,nodev,sync,data=ordered,auto,user,exec 1 2

    It says that /media/LINUX will be backed up and checked with fsck during system start up. At the end on the line, number "1" is the backup option, and number "2" is the fsck option.

    You may desire to change the line to:
    /dev/sdb1 /media/LINUX auto rw,nosuid,nodev,sync,data=ordered,auto,user,exec 0 0

    *Dump option uses the number to decide if a filesystem should be backed up. If it's zero, dump will ignore that filesystem.

    *fsck looks at the number in the last column to determine in which order the filesystems should be checked. If it's zero, fsck won't check the filesystem.

    Now the computer will start up well, on both situations: USB disk connected or disconnected.
