ssdup's Introduction

<<<<<<< HEAD

Start

orangefs_install/sbin/pvfs2-server orangefs-server.conf wb_info.conf -f
orangefs_install/sbin/pvfs2-server orangefs-server.conf wb_info.conf

Sample wb_info.conf

buff_path_1 : /mnt/ssd1

buff_path_2 : /mnt/ssd2

buff_threshold : 8GB

high_watermark : 0.45
low_watermark : 0.3

rs_length : 128

Compile

chage src/io/trove/trove-handle-mgmt/module.mk to:

DIR := src/io/trove/trove-handle-mgmt
SERVERSRC += \
	$(DIR)/avltree.c \
	$(DIR)/my_avltree.c \
	$(DIR)/trove-extentlist.c \
	$(DIR)/trove-ledger.c \
	$(DIR)/trove-handle-mgmt.c

Other operations remain the same as orangefs
