Storage Pooling / Re: Question On External Drives
« on: Today at 07:52:39 am »
Nothing will happen if using RAID-F outside of the maintenance tasks (Verify/Validate) aborting.

This can happen if there is a file in the array of the same name and path as the landing disk file.
That or the files could potentially be locked by other programs.

There should be entries in the logs relating to the errors in moving the affected files.

General Discussion / Re: How To Pool External USB Drives?

USB disks are pooled the exact same way internal disks are.

The one thing to remember is that you should avoid using USB disk in a tRAID parity RAID configuration since USB controllers are not designed for heavy and prolonged loads.

Please see this topic in regard to the forensic plugin:,4175.msg26989.html

In the most likely case, you will just run the Verify & Sync task, which will correct the parity.

Block failures are not the expectation. However, they are not critical if they happen once in awhile. Frequent block failures are what you should worry about.

Block failures can come from a variety of sources including memory errors, which you have no control over. This is why servers typically use ECC RAM.

I get a similar error on a new set of disks after initial build. While I know it's not out of the realm that a disk has a problem no smart indication of issue.

Is this expected? Or should a freshly created / sync'd storage pool return zero bad blocks?
You should post the exact error you are getting. A "similar" answer will likely not do any good to your specific issue.

Negative error codes are Windows error codes:
A positive code (Error Code = 999999999) is a parity generic code. It simply means that the parity is out of sync with the data. You should therefore run the Verify & Sync task.

Snapshot RAID / Re: Second Array Different Than First??

You can only have a single Cruise Control configuration. This is because RAID-F currently limits you to a single storage pool per system.

Storage Pooling / Re: DRU Setup

A spanned PPU is a bad idea. If your largest disk is a 4TB drive, make it the PPU.
I thought you had a 8TB disk being used a PPU and why you were spanning the data disks.

I would go with option 2 as it evens out the disks. This evens out the risk level but also should give you slight more consistent performance during RAID tasks.

Snapshot RAID / Re: BSOD or reboot when initialize raid
« on: September 11, 2017, 05:40:50 am »
The issue is the maintenance tasks (Verify and Validate) will have similar power requirements.
So, address the PSU issue properly.

If you can find the deleted files (backups, re-download, etc.), that will do the trick. The more of the missing files you can find, the more you can restore of the data.

Snapshot RAID requires that you Update the parity after big data changes. This is unless you have the recycle bin feature enabled.

The fact that the RAID was not updated since "last year"  means the parity has not bee valid for just as long.

Analyze your crash dump:

Likely, you have power issues for the load.

General Discussion / Re: Flexraid tRAID with bunch of single Raid0 arrays
« on: September 07, 2017, 01:49:49 pm »
It is up to you to formulate the advantages/disadvantages. It is all about what you are trying to achieve and willing to contend with.

For as long the RAID0 volumes are hardware RAID, it should work minus being able to use SMART from the tRAID Web UI.

Make sure those shortcut are disk mounted.

The logs clearly spell out what data it sees as missing. Just look at the files flagged and make sense of them.
It could be that you moved or deleted too many files from those DRUs causing the parity to be invalid for restore purposes.
