Assumes that the REST connector is fully setup and working
Install Target
Install sfused
yum install scality-sfused
Config basic FUSE parameters
config basic sfused parameters (in /etc/sfused.conf)
dev = 2 bstraplist = 192.168.122.161:4244,192.168.122.171:4244,192.168.122.161:4246
Config SPARSE parameters
Config sparse Set following parameters in /etc/sfused.conf:
Set serialization of each of the 4 cache to 0
serialization = 0
config following sparse parameters:
[ino_mode:2] type = sparse cache_stripes = 0 cache_md = 0 pattern = .* sticky = 1 stripe_size = 1048576 fsync_on_close = 0 Validate sparse Turn on debugging
Add sfused_options into /etc/default/scality-sfused
SFUSED_OPTIONS="-T15"
and then start sfused daemon.
/etc/init.d/scality-sfused start # note: restart will fail if it's not running
