yum install -y yasm
git clone https://github.com/01org/isa-l.git
cd isa-l
./autogen.sh 
./configure 
make install

Installation

cd ${SRC_DIR}
mkdir build
cd build
cmake ..
make
sudo make install

Configuration

1./*prepare disk, from 0 to num_of_your_disks for each node*/
mkdir -p /opt/sdfs/data/cds/0
mkfs.ext4 /dev/sdx
blkid /dev/sdx
echo 'UUID="you-disk-uuid" /opt/sdfs/data/cds/0 ext4 user_xattr,noatime,defaults 0 0' >> /etc/fstab
mount /dev/sdx /opt/sdfs/data/cds/0
/*prepare a ssd or nvme for redis mount*/
mkdir -p /opt/sdfs/data/redis/0
mkfs.ext4 /dev/sdy
blkid /dev/sdy
echo 'UUID="you-disk-uuid" /opt/sdfs/data/redis/0 ext4 user_xattr,noatime,defaults 0 0' >> /etc/fstab
mount /dev/sdy /opt/sdfs/data/redis/0

2.modify config, only modify one of your nodes:
vim /opt/sdfs/etc/cluster.conf

update hosts in first column, cds with num_of_disks for example:

auto1.host155.vmnode31  redis[0,1] mond[0] cds[0,1,2,3,4,5,6] nfs[0]
auto1.host155.vmnode32  redis[0,1] mond[0] cds[0,1,2,3,4,5,6] nfs[0]
auto1.host155.vmnode33  redis[0,1] mond[0] cds[0,1,2,3,4,5,6] nfs[0]

vim /opt/sdfs/etc/sdfs.conf 

update gloconf.networks, if only single host,then add config:solomode on; for example:

networks {
    192.168.140.0/8;
}

vim /etc/hosts

update hosts, for example:

192.168.140.31 auto1.host155.vmnode31
192.168.140.32 auto1.host155.vmnode32
192.168.140.33 auto1.host155.vmnode33

Create

/opt/sdfs/app/admin/cluster.py sshkey --hosts auto1.host155.vmnode31,auto1.host155.vmnode32,auto1.host155.vmnode33
/opt/sdfs/app/admin/cluster.py create --hosts auto1.host155.vmnode31,auto1.host155.vmnode32,auto1.host155.vmnode33

Usage

sdfs --help
