# aoe-revalidate(8)

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.

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.

## EXAMPLE

```
nai# aoe-stat | grep e1.9
     e1.9        82.348GB   eth0 up
nai# < /dev/etherd/e1.9 sleep 600 &
[1] 13006
nai# aoe-revalidate e1.9
nai# aoe-stat | grep e1.9
     e1.9       164.696GB   eth0 up
```
