Fixed In Version:	ovirt-3.4.0-beta2	Doc Type:	Enhancement
Doc Text:	* Data centers with compatibility version of 3.0 do not support mixed types (aside for ISO/export domains), first storage type to be attached, the rest will have to follow (e.g. if I attach an NFS domain and try to add an iSCSI domain the operation will fail) * Live storage migration is only supported when the source domain has the same storage "subtype" (file/block) as the destination storage (e.g. an NFS migration to Posix will work since both are file domains, NFS to iSCSI will fail and vice versa)	Story Points:	---

Description Allon Mureinik 2013-12-04 10:35:46 UTC

Description of problem:
Allow attaching domains of several types to a single Data Center

The limitation is fictitious, and there is no gain in maintianing it.

Comment 1 Sven Kieske 2014-01-08 12:34:42 UTC

Can this be done for 3.4? It would be HUGE!

I don't know what parts of the code need to be changed.

I would do it myself with some guidance and submit the patches in my free time, if my java skills suffice.

Comment 2 Juan Pablo Lorier 2014-01-08 13:33:59 UTC

Getting this limitation out of the way asap would be a great enhancement.

This RFE is about allowing to mix domains of shared types (iSCSI, FCP, NFS, Posix, Gluster) together.
There are a couple of limitations though:
1. you cannot mix local domains with shared domains.
2. you cannot live migrate a disk from a file based domain to a block based domain.

TCMS Test run was executed:

Verified using RHEV 3.4 av2

This is an automated message: moving to Closed CURRENT_RELEASE since oVirt 3.4.0 has been released.
