    100% space usage - /dev/mapper/FlexBack-root

    Any idea what is going on here? That file is only 300k.

    root@FlexBack:~# df -h

    Re: 100% space usage - /dev/mapper/FlexBack-root

    The /dev/mapper/FlexBack-root is a Linux LVM (or possibly a RAID) device file. This means that you've got Linux installed in an LVM or RAID configuration, and the 14GB you allocated for the Linux root (/) in that setup is insufficient.

    If you happen to have it installed, I recommend you use the kvpm or system-config-lvm tools to try to increase the space allocated to the FlexBack-root logical volume. If you don't have either of those packages installed, though, installing them might be difficult, since you don't have room left on the root (/) partition. Perhaps you can find something to delete on there to make room -- maybe temporarily uninstall OpenOffice.org or some other big package.

    If you need more help, please post the output of the "sudo lvdisplay" and "sudo pvdisplay" commands, preferably between [code] and [/code] strings for legibility. The output of "sudo fdisk -l" may also be necessary.
