Thanks @b-earl for the heads up! I guess I shall not touch it for the time being...

General Discussion / Reinstall OS without NZFS-CONFIG.db backup
« on: January 09, 2019, 10:17:32 am »
I am undergoing a failing OS disk on my NAS that is running Flexraid t-RAID. The current OS is Windows Server 2012 R2, and I plan to reinstall the OS into Windows 10 (because I couldn't run Blackblaze or Google FS on the server OS). The data on the FlexRAID array is still intact in every way.

The failing disk is preventing me from backing up the NZFS-CONFIG.db file -- which is not a big issue as I could setup the array again without data loss -- at most I would only need to re-calculate the parity data. However, would I be able the re-activate the license after the OS install? Can I use the same unlock key that I used to activate FlexRAID on Windows Server 2012 to activate it on Windows 10? There will not be any hardware change -- but the drivers will probably be different.

Thank you.

Removing the browser cache works. Thank you!

I have just upgraded my tRAID from 1.0 to 1.1 and when I try to sign in to the admin portal using Chrome, an error shows on the lower right corner and I'm not able to access the dashboard. However, on Edge and Firefox Quantum the portal works fine.

What could be the problem here? Thanks in advance.

General Discussion / Files randomly left behind on Landing Disk
« on: September 21, 2017, 12:05:46 pm »
I have a 7-disk configuration on tRAID that has been running for a few years, with a 128GB SSD formatted as a single ReFS partition being used solely as a landing disk.

Of late, I notice the landing disk buffer gets filled up very quickly, so I took a peek into the drive and noticed that the available storage is 50-60GB less. I make sure the landing disk is not in use before I took ownership of the hidden folders trying to find out what's hogging the space. To my surprise, there are a few old files being left over on the landing disk, which had already been copied to the array long ago. I am not able to find any pattern because it happens rather randomly - the files that are left behind have different creation dates and during the same period there are many other files of the same type and size which got transferred to the array and removed from the landing disk.

There is no implication to data integrity (so far) and the verify tasks always turn out to be successful. If anything the only compliant is that I need to check the available space on the landing disk regularly.

If anyone has any suggestions on why this occurred, I'd be happy to investigate further. Thanks!

I believe I'm using the latest version (host v1.0.0 2015.11.09 and web v1.0.0 2015.11.12).

However, I must have misread your instructions as I do not see any log settings. After firing up the portal, I double-click on my Host icon when the tree is expanded, and a popup window shows in the lower right corner stating "Operational info: host_name no further details available...". When I double-click on "Settings", it shows the license information with OS, Broker and Kernel version.

When I click "Add a new host to manage", it does show a screen with the "Log Level" setting - but I assume this is to log the web client actions and not the host/broker actions?

Your help is appreciated. Thank you

I am using t-RAID on a 5-disk array running on Windows Server 2012 R2. I have followed the Wiki to add and set the System Environment Variable of "FLEXRAID_NZFS_LOG_LEVEL" to "error". Restarted it of course. But it is still churning out log files at an alarming rate -- 15GB of them in just a couple of days.

After reading the logs, I notice most of the log entries are "OnSetAllocationSize" and "OnSetEndOfFile" events -- which should not even appear under the "error" verbose setting at all. It seems the System Variable entries was not observed and simply ignored by the FlexRAID host service.

Is there anything else I could try? Thank you.

General Discussion / How to quickly identify file(s) in a specific range?
« on: December 21, 2015, 02:35:46 am »
Is there a way I can quickly identify a specific file (or files) that is stored within a range of the storage pool?

E.g. I want to know what are the exact files stored between xxxxx150 to xxxxx166 bytes.

Thank you!

General Discussion / Landing Disk Exclusion Rule for uTorrent *.!ut files
« on: November 21, 2015, 09:37:02 am »
I use a 128GB SSD as the dedicated landing disk for my T-RAID Storage Pool, and would like to experiment exclusion rules to the landing disk as there seems to be some issues with uTorrent when adding a big task with landing disk enabled -- even with the pre-allocation setting enabled.

As such, I would like to have an exclusion rule such that when the file name extension is !ut AND when the file size is >10GiB, the save would go directly to the array and bypassing the landing disk.

After reading the wiki, the closest thing I could come up for the above rule as Exclusion is

The above does not seem to be working. It might have something to do with the "!" being treated as negation but *.\!ut does not seem to work either...

Any help on the topic is appreciated. Thank you!

Performance Tuning / Optimizing Landing Disk for uTorrent
« on: May 10, 2015, 01:31:10 pm »
I am using a relatively large SSD volume formatted in ReFS as a landing disk in a t-RAID config. Is there a way to configure FlexRAID mover thread to leave the incomplete files (*.!ut) on the landing disk and only move them after downloading is completed?

In addition, I am seeing multiple WriteToDisk errors when working with very large (>20GB) torrents, which I suspect is caused by the tiered storage model (landing disk --> array).

Any help is appreciated!
