Re: [Users] Q on ovirt datacentre and host storage types
2012/2/29 Deepak C Shetty <deepakcs(a)linux.vnet.ibm.com>:
Hi, got few basic Qs in my mind. Appreciate a response.
1) Why is it that the data domains must be of the same type as that of
datacentre ? What is the goal behind having
this constraint ? It seems useful to have a datacentre w/o having any
storage restrictions.. i should be able to add
hosts w/o worrying abt the storage types... why is it not so... looking to
understand the reason behind this design
decision.
vdsm has no such restriction. But spm works not properly with mixture
storage types.
For example, say NFS is master domain, and there is also an iscsi
domain in pool,
in this situation, the size of inbox/outbox in NFS domain is not
right, which will cause mailbox exception,
2) If i have a set of host systems all connected to shared FC storage, is
there a way for me to configure LUNs
exclusively for each host, meaning have ability to control what LUN each
hosts sees ? Can this be done using oVirt today ? My understanding is that
this cannot be done via ovirt, zoning of LUNs to host has to be done
separately and not via ovirt, is that correct ?
3) If i have to create and run 1000 VMs (say), how can i automate that using
ovirt, what is the best way to do that ?
thanx,
deepak
