Hi, I have configured a MAAS cluster and have block device 'sdb' attached to one of the nodes which I am using to deploy my charm as shown below:
After this I created a storage pool called maastest with attribute tag as 'sdb' and deployed my charm. In the MAAS controller console I see that the node status is "Failed Deployment" and I see the below error in the UI for the node on which I am trying to deploy the charm making use of MAAS storage: Installing for i386-pc platform. grub-install : error: unable to identify a filesystem in hostdisk//dev/sdb; safety check cant be performed failed to install grub! Command: ['install-grub', 'tmp/tmpqwTtyG/target', '/dev/sdb]' MAAS version is 1.9.4 and Ubuntu version : 14.04 I am new to MAAS and not sure why the above error is coming, can someone please help me in resolving this error.

The Juju storage documentation can be found here: https://jujucharms.com/docs/stable/charms-storage As an example, once you have your MAAS storage created and tagged, you could create a storage pool in Juju like this: juju create-storage-pool mypool maas tags=<maas-tag> And then you could add a storage constraint to deploy your charm like this: juju deploy <charm> --storage disks=mypool,1G I have not tried MAAS storage with Juju so you may need some additional commands. If anyone else has examples of combining MAAS storage with Juju please reply here to let us know.

I have tested this on AWS, making use of ebs as storage option. When I deploy the charm say "juju deploy ibm-spectrum-scale-manager --storage disks=ebs,1G", I am able to get block storage disks. My charm uses this disk and then creates a file sytem on top of that. I am able to test this on AWS, but now we have got a scenario where we have to deploy the charm on physical servers or VM's. We have configured MAAS for VM's and are able to deploy a sample charm as well using MAAS as cloud provider, but I am not sure how to make use of juju storage options incase of MAAS. Can you please provide us with any contact who can help us in making use of storage option with MAAS as cloud provider. Thanks and Regards, Shilpa Kaul
