2.2.1 Patrol Read feature settings
Scality recommends that you disable the Patrol Read feature on the LSI RAID controllers. The Patrol Read
feature runs periodically in the background checking for physical media errors. Patrol Read can kick off a
full consistency check if any errors are found, which can negatively impacting performance. Use Patrol
Read to supplement RING software error detection, which is currently available only on
object read
operations.
Scality recommends that you only enable the Patrol Read feature if you require error detection outside of
read operations, such as for disk scrubbing operations.
For more information, on the Scality document web site, in the left pane select Operations > How to >
RAID How To. In addition, documentation is available through the Avago Technologies portal.
