[gentoo-user] Harddisk priority
Hey I'm running a few processes in a cron-job, which makes the harddisk quiet busy, like the emerge --sync command. I know it's possible to nice them to use less CPU power, but is there a similar approach for reading/writing to the disk? Thanks -- gentoo-user@lists.gentoo.org mailing list

AFAIK it needs a kernel patch. -- BOFH Excuse #430: Mouse has out-of-cheese-error Michal 'vorner' Vaner pgpncUiwWKd7k.pgp Description: PGP signature

Knowing the name of what you're looking for sure helps... ionice is already installed by the lastest util-linux It seems to require the CFQ I/O scheduler, anyone know if it's a big disadvantage to run this scheduler instead of the Anticipatory ??? ...and does anyone know if this works in a default stable Gentoo installation?? -- gentoo-user@lists.gentoo.org mailing list
