[one-users] Datastores

Thu Aug 15 06:04:20 PDT 2013

That's exactly what happened , and on a clean install of 4.0 I was able to modify oned.conf and change the default datastore to /vmfs/volumes and it modified the original settings to use that for system(0) and images(1)

But on a clean install of 4.2 - it made me create new DS's and assign new system(102) and images(103) to the cluster so as not to use 0/1/2 which only expected local datastores.

Sorry to ask you this basic question, but, what exactly do you mean by

When upgrade my first test installation from 4.0 à 4.2  it changed those definitions from /vmfs/voluems to /var/lib/one/datastore

Do you mean that before the upgrade you did "onedatastore show <id>|grep BASE_PATH" and it pointed to /vmfs/volumes and after the upgrade the output was /var/lib/one/datastores ??

That shouldn't be happening at all.

The problem is - when I installed ON4.0 - I was able to re-direct the datastores to the /vmfs/volumes instead of /var/lib/one/datastores

So my system (0) and images (1) datastores did not have to be re-recreated

When upgrade my first test installation from 4.0 --> 4.2  it changed those definitions from /vmfs/voluems to /var/lib/one/datastores and I had to create my own datastores because they were not customizable by me

Originally thought it was part of the upgrade process - however when I built a clean installation of 4.2 I ran into the same problem 0/1/2 datastores all expect ONLY local volumes to the ON node and I had to create my own datastores for the cluster I built.

I would expect that I should be able to do one of the following

*  Delete and recreate the 0/1/2 datastores for use as VMFS volumes instead of locally mounted datastores

*  Modify or change those datastore definitions from locally mounted directories to vmfs mounts (which is what I set in the oned.conf file, and is adopted by the datastores)

Hi Michael,

would you care to explain the problem again? we don't quite understand what might be the issue. Do you have any further comments on the matter?

regards,
Jaime

An update to this -

I ran into the same issue with the DS names, before creating them myself - and they only point locally

I've created the system/images DS's on my ESXi hosts as 102/103 - and working on getting them to monitor

So far just get errors if I run /var/lib/one/remotes/datastore/vmfs/monitor

Are they any options at the end of monitor?

Ok Thanks. We've been looking at the upgrade process and it should not modify the base path of the datastores....

Cheers

Okay - I re-created the images DS from the Sunstone GUI and when I uploaded an image it now captures the right size - bug report maybe? I'll find out tomorrow when I transfer this to our DC lab machines from our office labs on a clean build

Subject: Re: [one-users] Datastores

The problem exists because when I upgrade from 4.0.1 --> 4.1.80 it recreated the images datastore with a path of /var/lib/one/datastores/1 and since I am on vmfs - it should be /vmfs/volumes/1

Is there a way to modify that path? Or will I have to re-create the datastore in OpenNebula and then rename the datastore?

Subject: RE: [one-users] Datastores

What does the monitor command look like from the CLI ? My logs only show successful response, not what it ran to check

But your right, if I do a list on the datastores - my system/images sore zero or nothing...so that's my issue

Ive been on the datastores - I will check the monitor data since that makes the most sense - something must be amiss there

My test env has 2 1tb volumes with one image and 2 running VM's - neither is more than 2% used

So monitoring seems the likelier culprit - Ill investigate that piece.

Subject: Re: [one-users] Datastores

This error is because of the space left in the datastore. Can you check that datastores are being monitor, and capacity data is get without errors? Are there any error or message relative to monitor datastores in oned.log? What is the size available/total shown in onedatastore show ?

Cheers

Can the images DS and the filestore DS be the same physical volume? Or must they be 2 separate volumes?

When I try to upload files to the images DS - I get

Req:752 UID:0 ImageAllocate result FAILURE Not enough space in datastore

I also tested images files - and I get the same error

I logged into the ESX host and made my way to the images datastore in /vmfs/volumes/1 - and as oneadmin (ssh , no passwd) I am able to create and remove files within the datastore itself

p.s. - commands also fail the same way via CLI and oneimage command
