Problem

In some cases, the following two issues are observed when storage migration is performed for a volume (with operations, such as subdisk move, mirror resync, mirror attach, mirror create, etc.) and SmartMove is enabled:


1. If the volume is taken offline, then the migration task completes abnormally and the volume may report data corruption.


2. If the data migration is performed for a volume of size 2 TB or greater, then the task never reaches 100% completion because of integer overflow while handling large offsets.

Solution

The two issues mentioned above have been fixed.

  • The first has been fixed by adding correct handling of error conditions so that the task is aborted if the volume is taken offline.
  • The second issue has been fixed by using a 64-bit variable for that purpose.
