Description Simone Tiraboschi 2014-11-12 11:08:39 UTC

Description of problem:
hosted-engine can now deploy the image VM over iSCSI.
Doing that it currently creates a storage domain over the selected LUN and just in order to this it requires more than 4GiB of space.
So, cause we round up to the next integer, the engine VM disk should be at least 5 GiB less than the LUN size.


Version-Release number of selected component (if applicable):
3.5.0

How reproducible:
100%

Steps to Reproduce:
1. deploy hosted-engine over iSCSI
2.
3.

Actual results:
the engine image should be at least 5 GiB less than the LUN size

Expected results:
try to do better maybe using a Direct LUN for the engine VM disk.

Looks like an RFE

Comment 2 Sandro Bonazzola 2014-11-18 15:04:05 UTC

After further discussion with storage team, we're not going to change things on hosted-engine for this.
