Description of problem: When running Smartstate Analysis on Azure Managed disks, we compose the name of the snapshot by appending the 20 characters string "__EVM__SSA__SNAPSHOT" to the os disk name string. There is a snapshot name limitation of 80 characters, so if the disk name exceeds 60 characters, the call fails with "The value of parameter snapshot.name is invalid. (cause: 400 Bad Request) creating SSA Snapshot" and the name of the snapshot. Version-Release number of selected component (if applicable): How reproducible: When the name of the Instance's managed disk exceeds 60 characters (including the GUID added internally by Azure). Steps to Reproduce: 1. Find a managed disk Instance with an OS disk name longer than 60 characters 2. Run Smartstate Analysis on it. 3. Actual results: The error above is returned. Expected results: Smartstate Analysis succeeds Additional info:
We will probably change the code to use the name of the instance instead of the name of the os disk. This should shorten it considerably. We can also shorten the snapshot suffix to _SSA_SNAPSHOT - this will shorten it to 13 characters from 20.
PRs https://github.com/ManageIQ/manageiq-providers-azure/pull/157 and https://github.com/ManageIQ/manageiq-smartstate/pull/44 have been added for this problem. The Azure provider PR has been merged upstream. Once the smart state gem has been updated the Azure provider Gemfile will need to be updated as well under the auspices of another PR.
Now moving to post as the manageiq-smartstate gem version 0.2.3 has been pushed out.
