# CBlock dozone configuration
|
||||
|
||||
This directory contains example cluster definition for CBlock/jscsi servers.
|
||||
|
||||
## How to use
|
||||
|
||||
1. First of all Start the servers with `docker-compose up -d`
|
||||
|
||||
2. Wait until the servers are up and running (check http://localhost:9876 and wait until you have a healthy node)
|
||||
|
||||
3. Create a volume: `docker-compose exec cblock hdfs cblock -c bilbo volume2 1GB 4`
|
||||
|
||||
4. Mount the iscsi volume (from host machine):
|
||||
|
||||
```
|
||||
sudo iscsiadm -m node -o new -T bilbo:volume2 -p 127.0.0.1
|
||||
sudo iscsiadm -m node -T bilbo:volume2 --login
|
||||
```
|
||||
|
||||
5. Check the device name from `dmesg` or `lsblk` (eg /dev/sdd). Errors in dmesg could be ignored: jscsi doesn't implement all the jscsi commands.
|
||||
|
||||
6. Format the device (`mkfs.ext4 /dev/sdd`). (Yes, format the while device, not just a partition).
|
||||
|
||||
7. Mount it (`mount /dev/sdd /mnt/target`).
