Spotřeba paměti se zdá být Ok a navíc tar funguje korektně. Pokud by bylo nedostakem paměti, tak by to mělo dopad i na tar, ne? Kvóty na disku nastavený nemám.

Vyzkoušel jsem kopírování přes rsync lokálně na Raspberry (abych ověřil, že není na vině ssh nebo něco na síti) a to při kopírování více menších souborů vedlo k chybě:

Raspberry jsem restartoval a začaly se objevovat hlášky:

Zvláštní je, že to zlobí jen na Raspberry, pokud disk připojím k oSuse, tak žádné problémy nepozoruji.
