    Nno worries, you have CSV files as backup in - /archive dir. Database isn't so big, to reload data will take about 2 hours ;)

    Cheers :)

    Hi Daniel! I'am not worry, it's only developer database with 0.5 TB of data. I take it as a case study and want to learn how we can to reanimate the server. Any ideas?

    In this case you have no choice, only a backup or may be only with fsck.
    The problem here is -
    or its a bad system configuration or its a bad hardware planing.
    man hier
    /media This directory contains mount points for removable media such as CD and DVD disks or USB sticks.
    I bet on a second. 
    Only an advise - if you will continue to use in mountable USB disk as a storage you will need to advance an epoch more frequently. You can do it manually or you can reconfigure Vertica to do it more frequently.

    Remember - Vertica is a disk based database ;)

    Thanks you very much for your participation! I'll try to repair fs by fsck. I think you're right - a problem in system configuration, but /media/twingo/... it's a internal HDD...
