4# The 3ware controller offers a choice of options related to handling of
5# mirror consistency in shutdown situations.
6#
7# If TWE_SHUTDOWN_NOTIFICATION is defined, the driver will inform the
8# controller on clean shutdown. On reboot after an unclean shutdown, the
9# controller will perform a complete mirror rebuild. This is the most
10# "safe" configuration, but it imposes a severe performance penalty in the
11# event of an unexpected reboot.
12#
13# In the alternate configuration, the controller assumes that all writes to
14# a mirror complete successfully. In the case of an unclean shutdown,
15# mirror corruption may occur if the controller is reset or power is lost
16# during a disk write. This configuration is more suitable if the system
17# has reliable power, but may be unstable for other reasons.
