    Hi All, and thanks to all respondees

    Seems kernal panics can happen if the swap partition is lost during use
    ( eg when the disk dies )

    Ill be adding metadevices for all my swaps this afternoon !

    Thanks Again

    Hi All,

    We use SDS to mirror all our 2 disk boxes, and im just wondering if
    there is any advantage in mirroring the swap partition ? I never have,
    but i just read a doc by Sandra Henry-Stocker and she does ( but doesn't
    explain why )

    I know if the disk failed that swap was on then swap would have to be
    moved to a good disk while the bad disk was being replaced, but in
    general normal activity any advantage - would swap having to write to
    two disks actually give a slower performace maybe ?

    Ta

    Laurence
