Snapshot RAID / Re: FlexRAID Snapshot - My Experiences

As per that wiki page, worry only about the type mapping. FlexRAID will typically handle the path mapping.

.. I know it has been mentioned in other threads that the update will cancel if a missing disk is detected. Does this also hold true for validates and verifies?
Validate is designed to validate what it can and report on what if finds missing. So, by design, it does not abort on disk failure.
Verify/Verify Sync will abort if a disk is missing.
Note that some files can be flagged as restored corrupted when they are actually fine. So, all files flagged as restored corrupted should be manually checked before determining whether they are indeed corrupted.

In just the last week, I had a 2 TB drive go missing, actually a complete failure of the drive. I was able to successfully restore using FlexRAID, and the bulk of the data remained intact. The restore showed successful, however, 75% of the movies files were corrupt. This leads me to believe that an update, validate or verify sent the corrupt data to the parity disks.
Only the Update and Verify/Sync tasks can alter the parity.
One thing to check is that you don't have a Virus Scanner or the likes intruding with the FlexRAID service process. There have been cases where they corrupt the in-memory data. So, do configure your AV to ignore the FlexRAID service process.

One more tip, do set your exclusions patterns when applicable. For those storing media content, most cataloging tools create metadata files and album/movie cover images, which they override every time they do an update. It is best to exclude those files from Snapshot RAID.

Is the error based on the destination or source?
As typical with Windows, there can be an issue of taking ownership of the files. It is all NTFS permission related. It is best to clean ownership information out of files that will be on a NAS.

I think the most critical thing is using Snapshot RAID for its right purpose or Real-Time RAID otherwise.

I see RAID-F being deployed in scenarios where it simply isn't the right solution over tRAID. The allure of the flexibility of RAID-F can be a trap.
If you struggle with the maintenance tasks or they become too cumbersome, then look into tRAID.
Snapshot RAID is designed for data that is static or semi static. The only time parity is compromised is when data is edited or deleted without the recycle bin feature.
When used properly, the worst case for Snapshot RAID are newly added files not being restored since they were not included in the parity.

If you are editing content too frequently or deleting files without the recycle bin feature, then you are taking a departure from the product's primary intended usage.

I highly recommend that Snapshot RAID users setup a staging disk where content lands first before being warehoused in a Snapshot array.

Now, Snapshot RAID absolutely need some improvements as you have hinted. The most critical one being the ability to auto can the Update task on SMART reports. This was not done initially because being able to get SMART is not guaranteed for all disks. Still, it should/will be an option. Please add a feature request to so we can track it.

There have also been many other enhancements, which are pending release. So, those fixes should improve things. No ETA on the release, but should be soon.

Hum... that's quite strange.
Try this, in your Tasks node (in the Host Explorer section), find all not completed tasks yet (if any) and try to delete them.

Then, go to: Advanced Operations -> Configuration Override -> Enable (and then clear the lock tasks).

What OS are you running?
Look into your device manager to see if the NZFS disk controller is properly installed or not. Try stopping and uninstalling the controller from the device manager, reboot, and re-install.

The driver is not running.
Reboot the system.

As adridolf is hinting, the broker service NZFSB is not running. Go to the Windows service manager and start the NZFSB service.

Check out tools such as:

If the Windows event viewer logs have nothing, then it is truly a mystery.

What version of the Web UI are you on?

Did you do the restore with the array online or offline?
If online, you have to restart the array for the restored disk to become available.

If that does not resolve things, do check the Windows event viewer for potential file system errors. Depending on how the original disk failed, there can be cases of file system corruption. If the file system was affected in any way, stop the array, hijack the source disk in question (by bringing it online in Windows Disk Manager), and run a file system recovery tool on it.


Go to: Advanced Operations -> Configuration Override -> Enable Configuration Override.
Then: Advanced Operations -> Configuration Override -> Clear All Locking Tasks.

Points taken.

I share the frustration - specially knowing all the fixes and new features already worked on and not yet released.
I am confident however that things will get back on track by year end.
