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<STRONG> RAW</STRONG> 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?<IMG id="smileyfrustrated" class="emoticon emoticon-smileyfrustrated" src="https://community.netapp.com/i/smilies/16x16_smiley-frustrated.png" alt="Smiley Frustrated" title="Smiley Frustrated" /></P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>Sorry for my not perfect english.</P><P>&nbsp;</P><P>&nbsp;</P> Wed, 04 Jun 2025 14:40:31 GMT Atlant 2025-06-04T14:40:31Z FAS 2552 Snapshot RAW filesystem issue https://community.netapp.com/t5/ONTAP-Hardware/FAS-2552-Snapshot-RAW-filesystem-issue/m-p/133971#M8327 <P>A few weeks ago our snapshots on one volume from NTFS became<STRONG> RAW</STRONG> format.&nbsp;</P><P>Briefly.
