Cause

Current PowerStore version does not support V attr.
 

Resolution

Workaround:
Remove V attr from files before copying to PowerStore SMB share.

In a future release, the behavior will be improved. Copy files with V attr to PowerStore SMB share lose V attr, and copy to NTFS or Windows SMB share.

Additional Information

V attr is ReFS integrity streams - File Integrity.
