On reboot after an unclean shutdown, the 13# controller will perform a complete mirror rebuild. This is the most 14# "safe" configuration, but it imposes a severe performance penalty in the 15# event of an unexpected reboot. 16# 17# In the alternate configuration, the controller assumes that all writes to 18# a mirror complete successfully. In the case of an unclean shutdown, 19# mirror corruption may occur if the controller is reset or power is lost 20# during a disk write. This configuration is more suitable if the system 21# has reliable power, but may be unstable for other reasons. 22# 23CFLAGS+=-DTWE_SHUTDOWN_NOTIFICATION 24 25.include <bsd.kmod.mk> 26
