[one-users] oneimage create command in ON3.4 and up

[Hyun Woo Kim]

Carlos,
I found what was wrong with my configuration;

onedatastore show default   reveals that BASE_PATH was pointing at the wrong path.
(This is because I started with one path and then later renamed the directory.)

onedatastore update default  did not let me change this BASE_PATH,
so I had to modify the DB content directly,

mysql> update datastore_pool set body="<DATASTORE> … </DATASTORE>" where oid=1;
and also had to restart oned in order to flush the memory contents.

After this,  onedatastore list now shows
-bash-4.1$ od list
  ID NAME                SIZE AVAIL CLUSTER      IMAGES TYPE DS       TM
   0 system                 - -     -                 0 sys  -        ssh
   1 default           434.9G 91%   production        0 img  fs       ssh
   2 files                 0M -     -                 0 fil  fs       ssh


Thanks again,
HyunWoo

Carlos,
in your email, you said,
"The datastore size is initialized to 0, and then populated with the right size"

What do you mean by "right size" here?
How do we set the right size in the first place?

Thanks,

Hi,
Thanks for the reply.

My oned.log has those messages
Tue Dec  3 08:53:08 2013 [InM][I]: Monitoring datastore default (1)
Tue Dec  3 08:53:08 2013 [ImM][I]: Datastore default (1) successfully monitored.

but I still can not do oneimage create with the same error message;
-bash-4.1$ oneimage create firstimage.template  --datastore default
Not enough space in datastore

Any other suggestion?

Thank you.

Hi,

The datastore size is initialized to 0, and then populated with the right size after the monitorization begins to work. Maybe there was a problem trying to monitor it. Take a look at /var/log/one/oned.log, you should have messages like these:

Fri Nov 29 17:29:19 2013 [InM][D]: Monitoring datastore default (1)
Fri Nov 29 17:29:20 2013 [ImM][D]: Datastore default (1) successfully monitored.

Or an error message from the drivers.

Regards

Hi,

Let me ask a basic question.

I just started testing ON4.2
and when I use oneimage command to register a first image,
I am getting the following error message

-bash-4.1$ oneimage create firstimage.template  --datastore default
Not enough space in datastore

I guess this is because the "default" datastore has "0M" size as shown below,
-bash-4.1$ onedatastore list
  ID NAME                SIZE AVAIL CLUSTER    IMAGES TYPE DS       TM
   0 system                 - -     -                                      0         sys      -        ssh
   1 default               0M -     production                0       img     fs       ssh


My question is, how can I increase this size?

I could not find relevant information from onedatastore help,
I guessed this size will increase when I add a new host, create a cluster, add the host in this cluster
and create a new virtual network and add it to the cluster etc,
but I am still getting the same error message..

Thanks in advance.
