Nuno Silva See this thread for a discussion on how the fix the issue with sm_config.

If that doesn't help, then you'll want to provide further details on your environment, ie:

XCP version and patch level
Details on your SR

Danp said in Backup & Snapshot Fail - SR_BACKEND_FAILURE_82:

XCP version and patch level

Hi Danp i'm already try to solve problem based on url that you refer without success

XCP 8.2 full updated

the disk is where and after 8 hours don't desapears

Danp

Nuno Silva I'm not sure that is the same issue. Have you checked the logs to see if the coalesce is aborting for some reason?

Nuno Silva

Hi,

2 to 3 hours after the migration of VM to master coalesce disappeared.

Thanks for help
