Hello, a doubt for 4.1 related to LUNs / storage domains to dedicate to hosted engine storage and normal data domain storage.
In oVirt docs here:
doesn't say anything special to differentiate iSCSI based and FC-SAN based storage for hosted engine.
Inside the docs of Self-Hosted Engine Guide for RHV (bot 4.1 final and 4.2beta ones) there is this general statement:
"
You must have prepared storage for your self-hosted engine environment. At least two storage domains are required:
- A shared storage domain dedicated to the Manager virtual machine. This domain is created
during the self-hosted engine deployment, and must be at least 60 GB.
- A data storage domain for regular virtual machine data. This domain must be added to the
self-hosted engine environment after the deployment is complete.
"
So far so good. But a bit below there is a particular note for iSCSI that I don't understand quite well
"
IMPORTANT
If you are using iSCSI storage, do not use the same iSCSI target for the shared
storage domain and data storage domain.
"
Does it simply remark that the LUN for the hosted engine storage (shared storage domain) should be different from the LUN(s) used then for normal VMs (data storage domain), or what?
I think it doesn't refer to the portal that for some reason needs to be different, correct?
Any clarification about this restrictions?
Thanks,
Gianluca
