Hello, I have TrueNAS-13.0-U6.1 running in a 10gb VM on Windows Server 2022 w/ 64gb allocated.
Drives are as follows: 60x 6TB HGST SAS in a shelf 4U-Quanta-M4600H-JBOD-60BL-S2-2P, with LSI 9200-8e HBA (IT mode) with SFF-8088
Bare metal specs: SuperMicro CSE-113TQ-R700 1U, Dual Xeon 6134, 256gb ECC DDR4

I have a VM for our workstation software that accesses the ZVol via iSCSI in Windows 10 environment and has created a NTFS drive at ~155 TB. We have about 55 TB used. I now understand that iSCSI may not have been the best choice, but that's where I am currently. I did not realize that iSCSI/NTFS are not suited to having multiple iSCSI initiators accessing it, and this weekend I was trying to set up another server so I connected the iSCSI to the Windows Server 2022 host and mounted the drive. Now I have multiple folders and files that are apparently missing.

Is this a permanent corruption and data is gone (or whatever can't be restored by a Data / Partition recovery in Windows on the NTFS)? I've tried disconnecting/reconnecting the Win10 iSCSI, I've tried re-creating the iSCSI configuration (Portal, extents, etc) in TrueNAS, but still data has disappeared.

Here's my various outputs, let me know if I need to provide more info...

Yeah, you've more than likely caused permanent data corruption. NTFS is not a clustered filesystem so the moment you attached the other server to the NTFS drive, it probably ate data. Not much you can from an ZFS perspective since zfs doesn't care about the filesystem that sits on top of it. You'd have to have a snapshot of the zvol/dataset from _before_ you connected the windows server and try to create a new iscsi target from the snapshot to see if you can get access to your data. Or if you have backups of the drive from some other program, you can try to restore from that.

And even that would require a significant amount of luck.
You might get something from ZFS data-recovery resvices, but it should be about the same.
