man aoe-revalidate (Administration système) - revalidate the disk size of an aoe device

NAME

aoe-revalidate - revalidate the disk size of an aoe device

SYNOPSIS

aoe-revalidate e{major}.{minor}

DESCRIPTION

The aoe-revalidate command tells the aoe driver to revalidate the disk size of an open aoe device. Normally the aoe driver will only acknowledge changes in an aoe device's disk size when the aoe device is not open. Aoe-revalidate will cause the driver to pause any I/O for the aoe device while revalidating the disk size. After revalidation I/O is resumed.

It should be noted that if an aoe device's disk size shrinks in revalidation any users may become hopelessly confused when their resumed I/O starts to fail.
