Question

I am trying to create a mobile Cloudstack 4.2 on 2 PCs. 1st pc = Xenserver 2nd pc = ACS 4.2

I am quite stuck in creating Primary storage during the Cloudstack UI as it prompt me "Something went wrong; You may go back and correct errors, Failed to add data store"

This is what I have do when trying to make my local storage as primary/secondary storage.

mkdir -p /export/primary /export/secondary

nano /etc/exports 

/export  *(rw,async,no_root_squash,no_subtree_check)

exportfs -a

mount -t nfs 172.16.109.4:/export/primary /export/primary
mount -t nfs 172.16.109.4:/export/secondary /export/secondary

usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /export/secondary -u http://d21ifhcun6b1t2.cloudfront.net/templates/4.2/systemvmtemplate-2013-07-12-master-xen.vhd.bz2 -h xenserver -F

Cloudstack-setup-management

I have successfully managed to enter the Cloudstack UI but fail at fail to add data store. Adding host was fine too.

I would like to ask if my step is correct? (Definitely wrong as I did not achieve my result)

and

Why it's wrong? How could I correct it?

Is it because I am stacking the folders?

Seeding the template goes into the NFS storage or it's mountpoint?

I have successfully deploy cloudstack with running VMS with a external NFS storage but it's too slow as my network is quite slow...

Was it helpful?

Solution

If you want to use local primary storage with XenServer you need at least two things:

  1. enable local storage in CS global settings (Global settings -> search for local -> set to true -> restart CS Management Server)
  2. make sure you have enough space allocated for the primary storage on the XenServer. Xen server uses LVM to create a primary storage volume. You can see the volume it's using by doing xe sr-list on you XenServer console (where sr stands for storage repository)

See the script in [1] for guidance on how to setup your XenServer for CS. Or feel free to use the script and make pull requests whenever you find something that is not right.

OTHER TIPS

Using cloudstack local storage has some key point you should pay attention to . I used kvm as cloud hypervisor but not too different form Xen.

  1. make sure you tag all the agent hosts and storage
  2. configure the agent.propery .
  3. create your own compute offering and disk offering
  4. create new vms using the new compute offering and disk offering .

Apache working with storage already list some tips for local storge but not so clear .You can refer to my personal blog here.Hope it helps.
