[RESOLU] Swap ?

[ernie]

Hello

A quoi sert le swap dans nas4free ?

Faut il activer ce point ou la ram suffit ?

Sur le net ce n'est pas claire sur le role et si c'est indispensable.

Je suis preneur d'information en fonction aussi si c'est une full install ou une Embedded install.

un résumé:
Why is swap necessary? After all, if you have a large amount of RAM, you shouldn’t need swap. And if you use ZFS, you should always have a large amount of RAM. That’s the ideal situation, but in practice it doesn’t work. Why? Because ZFS uses any available memory for cache.

Nas4Free allows you to install “embedded” or “full” software installations. I chose “embedded”, because this makes upgrades very easy, and it is simple to install this way on a USB flash device. This means you can dedicate all SATA ports to ZFS storage and not the operating system. With the embedded installation, Nas4Free does not create a swap space. Which means it’s up to the user to do this. It’s possible this isn’t an issue on the “full” installation. I don’t know; I haven’t tried it.

Il semble que c'est recommander d utiliser un swap. Par contre y a t il un seuil au niveau ram où s'est indispensable, je ne sais pas.
