Upgrade storage domains' version to V4 for 4.1 DCs
Hi all, Few moments ago I've merged the Data Center 4.1 upgrade patches (see [1]) The patches introduce a change in the storage domains' meta data to version 4 which are attached to a 4.1 Data Center Currently, there are no differences between version 3 and version 4, but the plan will be to add extra functionalities to V4 storage domains such as supporting qcow 1.1 For those of you which already have a 4.1 DC, you might encounter some problems since your storage domains are still configured as V3 and should be upgraded. For your master environment to be compatible with those changes the following changes should be performed: * In the engine side: 1. Change the storage domains version from V3 to V4: update storage_domain_static set storage_domain_format_type = 4 where id = (SELECT id from storage_domains where storage_pool_name = '{Data Center name}'); 2. Change the storage pool format type to 4: update storage_pool set storage_pool_format_type = 4 where name = '{Data Center name}'; * In the VDSM side: 1. call the upgradeStoragePool verb: vdsClient -s 0 upgradeStoragePool {storage_pool_id} 4 Please let me know if you encounter any issues Regards, Maor [1] https://gerrit.ovirt.org/#/c/63637/ https://gerrit.ovirt.org/#/c/63717/ https://gerrit.ovirt.org/#/c/63547/

It'd be great if we can document in ovirt.org somewhere what features are going to be available in 4.1 DC. I'm aware of qcow2v3, libgfapi, copy via HSM and discard. io=native everywhere is a EL7.3 feature, could be coupled with the DC level - not sure. I hope we can also increase the lease metadata space, but that's possibly not a 4.1 goal. Y.

2. Change the storage pool format type to 4: update storage_pool set storage_pool_format_type = 4 where name = '{Data Center name}';
* In the VDSM side: 1. call the upgradeStoragePool verb: vdsClient -s 0 upgradeStoragePool {storage_pool_id} 4
Please let me know if you encounter any issues

I've added a first initial draft at https://github.com/oVirt/ovirt-site/pull/477
