Reproducible with iSCSI and NFS storage domain.
2012-08-26 11:33:13,714 WARN [org.ovirt.engine.core.bll.storage.UpdateStorageDomainCommand] (ajp-/127.0.0.1:8009-10) [368d3694] CanDoAction of action UpdateStorageDomain failed. Reasons:VAR__ACTION__UPDATE,VAR__TYPE__STORAGE__DOMAIN,ERROR_CANNOT_CHANGE_STORAGE_DOMAIN_FIELDS
The flow to reproduce the bug is incomplete - in some scenarios this edit can work, see below.
Steps to reproduce:
1. Create a DC with two active SDs.
2. set the master to maintenance - both SDs will go down
3. Activate the SD that was not the master - it will force a reconstructions of the master metadata on this domain.
4. Try to edit the name of the SD from (3) - the error will appear.
In UpdateStorageDomainCommand, line 39, there is a check that only the name is changed.
This fails since the UI creates a new storage_domains object without the lastTimeUsedAsMaster property (defaults to 0), and the database version has it.
Merged upstream at commit #2abf376438ef81aeb4362a41ad4a512f7c29b32e
