A few weeks ago our snapshots on one volume from NTFS became RAW format.
Briefly. Server Windows 2012 R2 with mapped iSCSI target LUN on NetApp 2552 (single volume 2,5 Tb, single LUN 2,2 Tb on this volume). 5 weeks and before this date all snapshots maps like NTFS Disk and no problem at all. All snapshots after this date till now maps like RAW disks. Checkdisk and other tools on Windows says that the file system on original LUN is OK. What else can i do to fix this problem?
