Update:
This issue is fixed in software 2.2.3 and later
Description:
Expanding the capacity of a Virtual Drive within a Storage Pool by a size greater than the cumulative free unallocated space available after that Virtual Drive’s position in the Storage Pool, will cause some or all of the Physical Drives to be marked Dead. This will result in all Virtual Drives within the Storage Pool going Critical or Offline and becoming unavailable. Once this occurs, the Virtual Drives and the data in them are NOT recoverable. Physical Drives can be recovered by deleting the Storage Pool, creating a new one, and creating new Virtual Drives.
Root Cause:
When a Virtual Drive is expanded to include more space than the cumulative unallocated space available after its position in the Storage Pool, the Virtual Drive’s expanded capacity is inaccurately calculated resulting in errors in how the data is rewritten to the Physical Drives. This causes the Physical Drives to be marked ’dead’ which causes the Virtual Drives to be marked ‘offline’.
