Hello.
I found the following errors in the SMLog when XCP does a coalesce on a VDI.
Saw this after a LiveStoragMigration. The VM to which the VDI belongs is
running fine.
Here's the error:

I can attach the whole SMLog if required.
Thanks for any hint how I can get rid of this error and let the coalesce
finish successfully.
Kind regards,
Thomas Plant
