Optimize usage running using local storage:
sudo mkdir /opt/sdfs1
sudo docker run --name=sdfs1 --env CAPACITY=1TB --volume /home/A_USER/sdfs1:/opt/sdfs -p 0.0.0.0:6442:6442 -d gcr.io/hybrics/hybrics:masterOptimize usage running using Google Cloud Storage:
sudo mkdir /opt/sdfs1
sudo docker run --name=sdfs1 --env BUCKET_NAME=ABUCKETNAME --env TYPE=GOOGLE --env=GCS_CREDS_FILE=/keys/service_account_key.json --env=PUBSUB_PROJECT=A_GCP_PROJECT --env CAPACITY=1TB --volume=/home/A_USER/keys:/keys --volume /home/A_USER/sdfs1:/opt/sdfs -p 0.0.0.0:6442:6442 -d gcr.io/hybrics/hybrics:masterLinux Version Must be build from a Linux System and Windows must be build from a Windows System
Linux build Requirements:
1. Docker
2. git
Docker Build Steps
```bash
git clone https://github.com/opendedup/sdfs.git
cd sdfs
git fetch
git checkout -b master origin/master
#Build image with packages
docker build -t sdfs-package:latest --target build -f Dockerbuild.localbuild .
mkdir pkgs
#Extract Package
docker run --rm sdfs-package:latest | tar --extract --verbose -C pkgs/
#Build docker sdfs container
docker build -t sdfs:latest -f Dockerbuild.localbuild .
```
Step 1: Log into the linux system as root or use sudo
Step 2: Create the SDFS Volume. This will create a volume with 256 GB of capacity using a Variable block size.
**Local Storage**
sudo mkfs.sdfs --volume-name=pool0 --volume-capacity=256GB
**AWS Storage**
sudo mkfs.sdfs --volume-name=pool0 --volume-capacity=1TB --aws-enabled true --cloud-access-key <access-key> --cloud-secret-key <secret-key> --cloud-bucket-name <unique bucket name>
**Azure Storage**
sudo mkfs.sdfs --volume-name=pool0 --volume-capacity=1TB --azure-enabled true --cloud-access-key <access-key> --cloud-secret-key <secret-key> --cloud-bucket-name <unique bucket name>
**Google Storage**
sudo mkfs.sdfs --volume-name=pool0 --volume-capacity=1TB --google-enabled true --cloud-access-key <access-key> --cloud-secret-key <secret-key> --cloud-bucket-name <unique bucket name>
Step 3: Create a mount point on the filesystem for the volume
sudo mkdir /media/pool0
Step 4: Mount the Volume
sudo mount -t sdfs pool0 /media/pool0/
Set 5: Add the filesystem to fstab
pool0 /media/pool0 sdfs defaults 0 0
Running on a Multi-Node clusting on KVM guest.
By default KVM networking does not seem to allow guest to communicate over multicast. It also doesn't seem to work when bridging from a nic. From my reseach it looks like you have to setup a routed network from a KVM host and have all the guests on that shared network. In addition, you will want to enable multicast on the virtual nic that is shared by those guest. Here is is the udev code to make this happen. A reference to this issue is found here.
# cat /etc/udev/rules.d/61-virbr-querier.rules
ACTION=="add", SUBSYSTEM=="net", RUN+="/etc/sysconfig/network-scripts/vnet_querier_enable"
# cat /etc/sysconfig/network-scripts/vnet_querier_enable
#!/bin/sh
if [[ $INTERFACE == virbr* ]]; then
/bin/echo 1 > /sys/devices/virtual/net/$INTERFACE/bridge/multicast_querier
fi
Testing multicast support on nodes in the cluster
The jgroups protocol includes a nice tool to verify multicast is working on all nodes. Its an echo tool and sends messages from a sender to a reciever
On the receiver run
java -cp /usr/share/sdfs/lib/jgroups-3.4.1.Final.jar org.jgroups.tests.McastReceiverTest -mcast_addr 231.12.21.132 -port 45566
On the sender run
java -cp /usr/share/sdfs/lib/jgroups-3.4.1.Final.jar org.jgroups.tests.McastSenderTest -mcast_addr 231.12.21.132 -port 45566
Once you have both sides running type a message on the sender and you should see it on the receiver after you press enter. You may also want to switch rolls to make sure multicast works both directions.
