Maya is the storage orchestration system for managing storage for millions of containers. Maya can accomplish complex storage management tasks with deceptive simplicity. Maya can manage storage across multiple Maya-Realms (aka clusters/environments), that are co-located or geographically seperated and can also run from within a single host.
Well, the story does not end here. Maya manages itself i.e. maya manages maya.
It has been a long desire to make the lives of storage operators easier. Maya has been
designed ground up to implement just this i.e. manage & tune its own devops requirements.
Any *inx host that supports container can be converted into OpenEBS Storage Host using maya.
Pre-requisites : ubuntu 16.04, wget, unzip
RELEASE_TAG=0.0.3
wget https://github.com/openebs/maya/releases/download/${RELEASE_TAG}/maya-linux_amd64.zip
unzip maya-linux_amd64.zip
sudo mv maya /usr/bin
rm -rf maya-linux_amd64.zip
Pre-requisites : ubuntu 16.04, git, zip, unzip, go.
mkdir -p $GOPATH/src/github.com/openebs && cd $GOPATH/src/github.com/openebs
git clone https://github.com/openebs/maya.git
cd maya && make dev
NOTE: When there are multiple IPs on the machine, you can specify the IP to be used for management traffic using -self-ip
Example : Assuming 172.28.128.3 is where you require the management server to be running.
ubuntu@master-01:~$ maya setup-omm -self-ip=172.28.128.3
Example : Assuming Maya Master is reachable on 172.28.128.3 and you would like the OpenEBS Storage Host to communicate using 172.28.128.6
ubuntu@host-01:~$ maya setup-osh -self-ip=172.28.128.6 -omm-ips=172.28.128.3
Start the maya services based on the configuration specified in the /etc/maya.conf.
maya load
Default maya.conf is created by maya init and can be modified to perform any of the following:
- Run as Storage Host only in a new or existing Maya Realm
- Run Maya orchestration services only
- Run both Maya orchestration services and also configure as Storage Host in a new or existing Maya Realm
maya load can also be used to re-load the configuration from maya.conf.
The following command will create a Maya volume using the default volume spec.
maya volume <name> [--spec <volume-spec>]
Each volume in maya is associated with a spec that defines the features for the volume like the capacity, jiva version, persistent store, etc., The default volume spec will create a new container and expose an volume with :
- capacity 100GB
- latest Jiva version
- data persisted to the directory /opt/maya-store/.
The volume will be accessible via iSCSI and can be connected from local host.
/opt/maya-store is the default store created when Maya is installed on the local disk. This can ge changed via the /etc/maya.conf to specify a different directory or disks (in case of single node setups) or can be an shared storage (in case of clustered setups).
