Tak musíš přijít na to kdo k tomu HDD přistupuje a probudí ho. (swap, logy, indexy atd....)

Případně více to rozepsat...

Jinak proč to chceš dělat pokud ten stroj neběží 24h a nepoužívá se ten HDD pouze občas pro načtení nějakého filmu tak uspávání nemá smysl.

Pokud na tom HDD je OS tak uspávání taky nemá smysl OS ho bude co chvíli probouzet.

Pokud se zařízení nepoužívá tak je lepší ho vypnout či uspat celé a při potřebě přes síť třeba vzbudit.

[ironman]

Proc? Ani sam nevim jen mi to prislo jako rozumny napad uspavat disk. Treba prez noc kdyz se nikdo na nic nediva a napouziva sem tak me napadlo ze by se HDD uspal a tim se snizila spotreba el. energie. Co se tyce logu ty sem prosel a nenasel jsem nic. Ale jak pises bezi a nem system takze uplne eliminovat vsechny zapisy je asi nemozne. Tak nic no necham to naplno

[lertimir]

Uspávání řeším tak, že systém je na flashce /tmp v paměti a na rotačních discích jsou jen data. Pak usnou když je nikdo nepotřebuje. A ty zápisy do flash beru tak že pokud se mi zapisy zničí tak jsou to provozní náklady. už teď mi drží 8 měsíc a stála 200Kč, samozřejmě je plně a pravidelně zazálohovaná.

Podivejte se u ext3/4 na parametr commit.

Kam mate pripojeny ten disk s daty? Kdyby byl pripojeny do /home tak by ho mohli probouzet uzivatele svoji aktivitou.

[tuxmartin]

Jeste by mohlo byt zajimave zakazat sync.
