aaaaand I found an inconvenient but solvable solution after that last error log, I installed it in a different directory outside of Program Files. Done and done. Although I don't know what was going on and I have never in all my years had an issue quite like that.... but now I can't add the license file onto it, presumably because it's in a different directory and file system - thankfully connecting it to the actual cloud solved that, but boy oh boy - that was frustrating

oh - log file, my apologies https://pastebin.com/daRUZhE1

Howdy - So I was trying to load up CloudDrive to add another cloud share on my PC, and I was getting an error where it wouldn't connect, so I checked services and sure enough it wasn't running. Tried to run it, got thought okay, let me try and repair it - no dice. Hangs. Also this error I've gone through tons of troubleshooting regarding the policies, added my local account and all admin accounts with permissions - nothing works. I simply cannot CloudDrive to work. DrivePool and Scanner - no issues. CloudDrive is simply impossible to install. The frustrating thing is the SHUTDOWN service installs and runs just fine, and I don't have an explanation to that.

Thank you Shane! I appreciate the quick answer. It sounds as if I will be reworking my server structure then. Maybe it is about time. Either this or I will be turning off my balancing temporarily.

Hi Mesonto, it's not possible within a single pool. If the requirement is just to avoid having to change shares on the LAN you could consider using nested pools (e.g. E and F supporting D)? Issues to consider would be 1, as the drives are already in use for D it would involve either a lot of background time adding/removing drives or some delicate manual work migrating/reseeding the pool structures, and 2, if you have any exceedingly deep path lengths (over 32 thousand characters!) in your existing pool you may not be able to nest it.

Present Config I have the following: pool 'D' which contains physical drives {U:18tb V:18tb W:18tb X:8tb Y:8tb} Wanted Config I wish to balance pool 'D' with {U,V,W} at a 50% balancing ratio and {X,Y} at a 90% balancing ratio. I do not want to separate the 5 physical drives of pool 'D' into 2 different pools of drives... such as pool 'D' containing {U,V,W} and adding another new pool 'E' containing {X,Y} (however if I did the balancing is obviously easy, but I will have to reset program drive pointers on different machines throughout my home office) Question Is this possible under the default program? If not is there a plugin to do this? All help is appreciated, thank you!

Thanks a lot for your answers, very much appreciated! Waiting for point 1

1. @Alex does the GUI or JSON take precedence in a conflict? 2. I agree there's a couple of parts of the docs that need updating. 3. DrivePool operates on three levels, driver (handles direct file operations) and service (handles balancing, consistency and other scheduled tasks) and GUI (handles the user actions like adding disks, creating pools, etc). The GUI relies on the service which relies on the driver. There's also a command line tool (dpcmd, must be run as administrator) that can talk to the driver (but can only do a small subset of things the GUI can do plus a few others). 4. The advantage of using DrivePool's duplication if you're using SnapRAID is that your entire pool would remain readable during one or more disk failures (depending on how you've organised your disks) without needing to rebuild from the latter's parity, and you can resume writing as soon as you drop the bad disk. The disadvantage of doing so is of course any additional parity computation overhead (depending, ditto) and the additional storage consumption (since every file will take up twice as much - or whatver duplication multiplier you've set - of the available space in the pool, assuming a basic implementation).

Is this active? Any chance of getting an updated invite?

Hello! I'm testing the application since 2 days now, and I've been reading a lot of documentation and tips on various locations including this forum, reddit, and the manual. Still I have a few questions that I was not able to find. 1. When I first installed DrivePool, I saw on the GUI settings (on the title bar) an option "Verify after copy". Since I'm a bit paranoid (probably as a lot of people here), and since I care about my data to some extend, I've enabled this option via the GUI. Of course I know it will impact the performance a bit but this is not an issue for me right now. However a few times later, I went into the JSON settings file and I saw the same option, left to the default (false), and not overrided. So my question is: What is taking precedence here for the same option? Is it the GUI or the JSON setting? I can already see that the documentation https://wiki.covecube.com/StableBit_DrivePool_2.x_Advanced_Settings could maybe be improved for this setting telling about the GUI option as well. 2. Then since I have 10 spinning disks and 4 NVMe, I tried to play a bit and created a pool only with NVMe, but I noticed all of my other drives were continuously spinning, which was unusual. And then I found this thread from... 9 years ago! https://community.covecube.com/index.php?/topic/1674-drivepool-service-making-constant-disk-access/ Telling to disable "BitLocker_PoolPartUnlockDetect" option, which I did, and which worked! No disk spinning anymore. Still I'm a bit sad that 10 years later after the thread I found, someone like me still struggled on that and that nothing was done here to improve the User Experience, like a warning or even a notice somewhere on the doc or the app, telling that the HDD drives will continuously be polled -and continuously spinning- unless the user manually disable this option. 3. Since I had to restart the service for point 2, I've noticed something else. Even with the DrivePool service stopped (via services.msc), I still had the pooled drive active and could even write files in there, and the file was apparently properly write on a disk. How is that possible with the service stopped? 4. Since I plan to use SnapRAID along with it (along with DrivePool Scanner but haven't tested it yet), can you tell me what would be the advantage of DrivePool duplication knowing that SnapRAID would restore my files back as well? Thanks in advance!

So I am in the process of migrating my single pool to a subpool configuration. I added the single pool to a new pool and seeded the data into the new poolpart folder on the now sub pool. Duplication is enabled on the sub pool. After remeasuring and verifying duplication on both pools, the new top level pool is showing half of the total space as "other" data. Everything on the subpool is showing as normal. I'm not certain if this is expected behavior due to the subpool having duplication enabled or some kind of bug that I've encountered with the UI. I've tried resetting drivepool to defaults and remeasuring but it's still the same afterwards. My plan is to migrate my SSD's to their own subpool so that I can store certain file types from within the same folder on either the SSD subpool or HDD subpool each with their own duplication levels. Ideally I would like to see the top level pool show everything as unduplicated data.

Hi surfercool, it's unfortunate that you've had no response to your ticket since there seems to have been a small rash of BSOD issues with ~2.3.11. You mention 2.3.9.1612 does not crash on your system, is there any reason not to stick with it? That you're getting such poor rates and constant crashes, and that DrivePool is being triggered to constantly perform balancing operations (I might suggest you turn off automatic balancing to see if that helps), does have me curious as to what hardware you're running DrivePool on and what software you're running alongside it. Is it something really heavy in terms of disk IO?

Despite waiting nearly a month, I have yet not receive any updates or responses from Covecube regarding this matter. It appears that my problem are not being addressed. Windows Spaces is currently storing approximately 18 million files, totaling 3TB. I have not experienced any issues thus far. There has been no file fragmentation, even though StablebitPool has continuously generated a significant number of file fragments through its constant balancing and moving operations. In some instances, a 200kB file contained up to 100 fragments. The SSD cache performance is underwhelming. The utilization of the SSD cache alone results in extremely slow copy speeds. The observed slow copy speeds can be attributed to performance limitations within the DrivePool software. When utilizing PrimoCache in conjunction with Windows Storage Spaces, a substantial performance improvement was noted, with copy speeds exceeding 200MB/s for identical files. Conversely, Stablebit DrivePool exhibited significantly lower transfer rates, averaging between 10 and 20MB/s, and was accompanied by frequent errors. It is important to highlight the pervasive instability of Stablebit DrivePool, which manifested in frequent system crashes occurring every 5 minutes or less. These system crashes, commonly known as "blue screens of death," occurred hundreds of times daily, measuring impossible.

Thank you for this, I spent like an hour fighting with it and then came here, the CloudDrive works perfectly, 10/10 loving this software.

Hello everyone, Can confirm this is a real concern. I recently experienced massive data corruption with files stored in OneDrive, and assumed OneDrive was at fault. Opening one file often resulted in viewing a completely different file, or losing the ability to view the file altogether (presumably because the extension had been changed to the wrong filetype). The source of the problem was installing a copy of OneDrive on each of my personal PCs, and a copy on my storage server with the intention of synching each instance together. The problem, as it turns out, was OneDrive being mapped to a pool on my server controlled by DrivePool. Unfortunately, I have lost some files completely, as OneDrive proceeded to overwrite all of the synched copies as well as the online copy. Since they weren't deleted, they weren't placed in the OneDrive recycle bin. Lesson Learned: Do not use any two-way synching service with Drivepool. I don't fully understand the mechanics of all of this, but I will only perform one-way syncs to my pool from now on. Edit: I was fortunately, able to roll-back my OneDrive account to recover everything.

works perfect have now top speeds like 240mb per sec

Ok thanks, shame it would've been really cool if I could diskless boot it.

Hi denywinarto, it's not possible to shrink the DrivePool disk/volume. You can only reduce the reported capacity (but not the reported 2TB "physical" size) only by removing disks from the pool.

Will Covercube ever release a Linux port of Drivepool and stable bit scanner? I would love to use my pool with Ubuntu server or better yet a Drivepool docker setup would be awesome. I know I could move everything over manually but moving 150Tb it would be a major hassle with the way Drivepool stores data and would require me to buy more drives and hardware which I really don't want to do. Thanks in Advance for your time.

So As we all know drivepool created a separate large disk in disk manager, in my case it's N, which seems to maxed out at 2047,97 GB Now I got this diskless program called ccboot which can boot the drive in disk manager to clients as long as it's below 64 TB. https://www.ccboot.com/64t.htm And since my pool is over 300TB it's no longer possible to do that.. My question is simple, is it safe to shrink drivepool disk in disk manager, and then maybe creating a smaller partition so that my ccboot clients can diskless boot from that drivepool partition?

Thanks for the reply. I've spent some time now trying various options, with different pool configurarions and trying to block unduplicated files from going on one pool and using the Ordered File Placement balancer, and disabling "Real Time Duplication", but I can't get it to behave exactly as I want. Not a knock at all at Drivepool as it's great, but doesn't have the duplication schedule options I'd need for this setup. I was using a windows tool do do my dive pool mirroring before, but I may put together a robocopy bat file to simplify it further. Thanks again for your help, Ian

Hi Ian, the short answer is I'd recommend keeping Pool A and Pool B separate and using a clickable or scheduled script/task to do the backup (e.g. via robocopy, FreeFileSync or similar).

Hi, you'll need to open a support ticket.

Hi, I recently reset my pc without deactivating my license, Now when I try and activate my license, It won't work. Any help to fix this?

Very simply, I have drives within my server called pool "A". I have drives outside my server in a NAS box called pool "B". I would like all content saved to Pool A, to be backed up after hours onto Pool B. Based on my limtited understanding, I can have balancing enabled for Pool A, and Pool B, and then put both those pools into a parent pool called Pool "C". Pool C can have folder duplication enabled where I can have it create a duplicate of specific Pool A folders, and since there is only one other drive in the parent pool (B) it will all naturally backup there, at whatever time or interval I set in Pool C's settings. I attached a super complex graphic to really bring this home To add some rationalle, I want Pool B (main backup) to auto-shutoff when not in use. In a perfect world, it would only duplicate/backup every 2-3 days as only a few gigs of content will be added to Pool A on any given day. I would rather keep the spin times low on Pool B and only fire them up every few days for 5-10 minutes rather than having them duplicate as the files come in. Does that sound possible, or is there a better way to accomplish this that doesnt involve new hardware? Thanks for your help, Ian
