Robocopy of folder redirection folders caused the volume to fill from ~1.5TB to the full 14T, as a result I cannot access the volume anymore

I'd appreciate some help resolving this issue. I was using robocopy to copy the contents from one iSCSI volume to another - moving folder redirection contents from the old to the new location. There was about 600-700GB worth of data that needed to be migrated.

I'm not sure what happened but I noticed that no domain system could access the redirected folders. I checked my TrueNAS target to see that the iSCSI share was at 100%. I looked at the Win2k22 initiator which showed the iSCSI volume as offline. I tried to get it online using disk management, but I had no luck. So, I used "diskpart" to bring it online. The drive properties show that 1.174T was used out of 14T. I used "shrink querymax" to see how much space I could reclaim, which was around 12T. However, when I used "shrink" I was told the disk was write-protected. I cleared that attribute from the disk, but as soon as I do that, the volume goes down. When I bring it back online, it's write-protected again, removing the write-protection causes the volume to go offline again, and so on and on and on - a cycle.

So, I'm a bit stuck. As you can see, I can't clear the attribute without having the drive and volume go offline, but whenever I bring the drive and volume online, the attribute goes right back to read-only.

Any help will be greatly appreciated to help me solve this problem.

Likely, your iSCSI target has messed up that volume. What kind of hardware does that TrueNAS run on? I'd simply format the volume and restore from backup.

I've been told that I messed up from the inception of the ZFS volume. I should have limited the capacity to 80%, not the full 100%. I am just wondering why things broke. This was working perfectly for months. The backup is another massive issue. I tried using Windows Server Backup (WSB) to backup the 1.75TB, but it WSB will not back-up read-only volumes.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
