Tips & Tricks

Foloseste aceeasi partitie SWAP in Linux si Windows
Daca esti in lipsa de spatiu si doresti sa folosesti aceeasi partitie swap si in Linux si in Windows, poti sa faci urmatorul truc:
1. Formateaza partitia ca si partitie DOS si creaza fisierul SWAP Windows pe ea, dar nu rula inca sistemul de operare.
2. Booteaza in Linux si s alveaza partitia intr-un fisier. Presupunand ca partitia swap se afla pe /dev/hda5, vom face
dd if=/dev/hda5 of=/etc/dosswap
3. Comprima fisierul dosswap:
gzip -9 /etc/dosswap
4. Adauga urmatoarele in fisierul /etc/rc pentru a pregati si instala swap-ul in Linux. XXXXX este numarul de blocuri din partitia swap:
mkswap /dev/hda5 XXXXX
swapon -av   
5. Adauga partitia in /etc/fstab
