    The entries in your fstab are causing the system to mount filesystems by
    label rather than by the device file. The label makes things convenient
    because, if things devices change their mappings, you can still mount
    the filesystem because you know what it's label is. The labels can be a
    pain for the same reason (like if you want to change system disks).

    Make sure your /dev/sdb1 and /dev/sdc1 have the labels mentioned in the
    fstab with the "e2label" command. Look at the man page for the usage.
    It should be pretty straight forward. I'm betting that whomever set up
    the mounts probably forgot to add the labels.
