Action

When a verify fails, redundant units will automatically resynchronize user

data through a background initialization. The initialize will not erase user

data, but will recalculate and rewrite user parity data.

If the unit was non-redundant, any data in the error location is lost. (However,

the error could be in a part of the drive that did not contain data.) A unit file

system check is recommended.

Under Windows, right-click on your drive icon and choose

Properties>

Tools> Check Now

Under Linux or FreeBSD use

fsck /dev/sda1. If you have more than one

SATA device, substitute the correct drive letter and partition number, such as

sdb2, for sda1.

The resynchronization of data that takes place during a background

initialization can slow down access to the unit. Once initialization has begun,

it cannot be canceled. You can pause it, however, by scheduling it to take

place during off-hours. For more information, see “Scheduling Background

Tasks” on page 166. You can also set the initialization process to go slower

and use fewer system resources. For more information, see “Setting

Background Task Rate” on page 165. (Initialization occurs at the Rebuild

rate.)
