Dik za info, to mne minulo.

Jinak jeste @ ten hw raid - i se ZFS je ten CPU load minimalni. A kdyz
se zvedne load na IO na tolik, ze by to melo vliv na CPU, tak uz to
davno ta appka, co to IO pouziva, natolik vybombila, ze to CPU nestiha
tak jako tak.

Mame s tim kousek zkusenosti, preci jenom nam nad tim ZFS nebezi uplne
malo veci.

Vypadek elektriny a tak? Prijdes maximalne zfs_txg_timeout asynchronnich
zapisu, o nic vic. (Default je 5 sekund).

/snajpa
