  1. I see, so then you need the opposite option in the balancer - "Equalize by free space remaining", I think? This should then give you what you want, for incoming new files?
  2. I'm confused - if you have real time balancing turned on, then this option has existed since... forever? Just make sure the disk space equalizer is above all other plugins besides Scanner (if you use that).
  3. No, that won't work at all. You can't duplicate and then force reads to only come from one disk. You would need a second SSD, and some file placement rules so that only your game folders are allowed on those disks. edit: why not just make a scheduled task to run a backup of the relevant game folders on the SSD, and copy them to the Drivepool in a "Game Backups" folder? Just a little batch file with some copy commands, then Task Scheduler to run it once a week?
  4. [1] Yes, it will only move the data from disk 2 if a balancing rule causes it to be moved (if you have disk space equalisation turned on, for example). Otherwise, it will stay put. [2] You could just set the drive-overfill plugin to 75-80%? Then if any disk reaches that capacity, it'll move files out? Personally, I assign a pair of landing disks for my pools. Two cheap SSDs where incoming files get dumped. DP then moves them out later, or if it fills up. Note that the disks should be larger than the largest single file you would put on the pool. If cost is an issue, you could try the following setup with existing hardware instead: Install the SSD optimizer plugin Tell DP/SSD Opt. that Disk 2 is an SSD and un-tick the "archive" setting Make Disk 1 and 3 "Archive" drives Change your file placement rules so that only unduplicated files go on Disk 2, and only duplicated files go on 1 and 3 That way, all new incoming files get put on "Disk 2", then later when your duplication/balancing rules engage, it will move the data off of Disk 2 entirely, and duplicate to 1 and 3. This assumes you do not have "real-time duplication" enabled. If you still need the total capacity of the 3 disks, then perhaps a small investment in a 120/240GB SSD to use as a landing drive might be a good idea, and substitute "Disk 2" with "SSD/Disk 4" in the above setup?
  5. You should be able to pass the iGPU, but I am using old Xeons so I can't test it. Keep in mind that you then lose the host video if you do that. I'm no Hyper-V expert though, I use Proxmox. I do know that all four of these options need to be ticked when adding a PCIe GPU in proxmox: Is the Hyper-V equivalent obvious to you? I've only ever used Hyper-V on my local PC for testing and no passthrough. I have been testing VM pass-through of my HBAs for over a year now, and just moved my bare-metal machines over to VMs as the setup passed my testing to my satisfaction. Remember to de-activate your bare-metal Drivepool/Scanner licenses FIRST though... or you'll end up pestering Mr Drashna to get that mess fixed.
  6. No problem. Here is a somewhat old thread on ReFS: https://community.covecube.com/index.php?/topic/3296-refs/#comment-22766 There seemed to be some concern over different ReFS versions not being compatible (yikes!), so not sure if that is still a concern?
  7. I pass through the HBA for Drivepool. I use Dell Perc H310 cards and the SMART data is all visible, as it should be because my Windows VM has direct access to the HBA. edit: Wrong Chris I know, but hopefully helpful?
  8. Just move the files you see in "E:", to the new drive "K:". You only have one disk in the pool so far?
  9. It's odd that the form isn't working for you - I literally just used it the other day. Try another browser to be sure? But just tag @Christopher (Drashna), or use one of the contact methods in his profile: He will help you sort it out.
  10. It literally duplicates the data, so a 30TB pool has space for 15TB of data if you select 2x, 10TB if you selected 3x, etc. It will still show as 30TB in Explorer though. So yes, if you have 30TB of actual data, you need 60TB of disks for 2x duplication. The files in the pool are stored in a hidden folder in the root of each drive. Change your Explorer options to show hidden files, and navigate into the long-named folder starting with "PoolPart." and you will see all your files and a ".covefs" folder at the top. Simply move everything except the ".covefs" folder out to another location. Where did it used to belong? If the old home of the data is still available, you can copy the content of each PoolPart folder to the same place, and it will all merge in the usual Windows Explorer manner - ie, with that popup to confirm merge/overwrite. If the old home is not available, just copy the file to the root of each disk. When you are done with that part, you can delete any remaining hidden folders. Hopefully that's clear?
  11. These two options leave your data on the removed drive:
  12. Huh? You just tick "fast removal", and it leaves the data on the disk alone.

    Hard Links?

    Just configure the metadata to be stored elsewhere - it should really be on an SSD anyway, for speed. It should be defaulting to using the system (C:/) for metadata. Personally, I use a dedicated cheap and small (120GB Sandisk Plus) SSD for mine.
  14. Disk manufacturers use the definition of a kilobyte as 1000 bytes vs 1024 bytes on the computer side. That's where your "missing" space is. There is no way to unlock more space, nor has there ever been a way.
  15. Yes, Drivepool creates a new drive for the pool. It's auto-assigned a drive letter but you can change it using the usual Windows method. It appears as a (mostly) normal drive, though disk management might only show it as "2048GB", as it has to report a value, and since the pool can grow and shrink, it supplies a fixed value. You still see the correct values in anything that isn't a partition manager though. The physical drives can have their letters removed if you want, or mounted to folders instead - I use C:\DP\ to mount all mine in case I want to access them (unlikely). Keeps the drive letter clutter down. I have no idea about ReFS, I will tag in @Christopher (Drashna) for that part Or maybe someone else can answer.

    Lost pool

    ah ok, and the 3 drives that were in the pool are now completely empty? (both hidden and system hidden files visible)
  17. I do not think you can tell which disks contain a certain file from within DrivePool, but they are stored as normal files and visible in Windows Explorer (if you mount the individual drives to a folder, or give them drive letters) - so using Search would tell you. I am not certain that Scanner helps with BitRot - that is why many people use SnapRAID in combination with Drivepool. It's a free software tool that allows you to add parity to your DrivePools. I don't use it myself though.

    deleted disk

    When you say "deleted" the drive, what do you mean exactly? Deleted how, and where?
  19. What do you mean by skip existing? Surely they are empty if they are new?

    Lost pool

    Wait, you deleted the parts folders? As in "PoolPart.[ID]" on each drive? That's where your files are... (were?) So what is the status of the individual drives now?
  21. Windows 10 can be prevented from creating thumbs.db on network drives using gpedit.msc - but on local ones, it should not be creating them, as W10 uses a central thumbnail and icon cache located at C:\Users\[USERNAME]\AppData\Local\Microsoft\Windows\Explorer So no need to turn off caching, just fire up gpedit.msc (from [WinKey]+R ) and change the following entry to "Enabled".
  22. Where are you uploading to? Is there a daily/monthly bandwidth cap? eg, Google Drive has 750MB/day IIRC.
  23. It's a bit too simple for a guide... just remember that you need more than one SSD if your pool has duplication. 2x dupe needs 2x SSD, 3x needs 3 etc. Also, keep in mind that the size of the SSDs determine the maximum filesize you can move onto the pool. I once had a pool with some 64GB SSDs as landing drives, and spend a while scratching my head when I couldn't copy across some large disk-image backups despite the pool having plenty of space.
  24. Dell Perc H310 or one of the variants are generally very cheap now - I use three of them, flashed to IT-Mode. They are essentially transparent interfaces now. I got them from ebay, and one from AliExpress IIRC. All under £30 delivered. You will need some of these cables: https://www.amazon.co.uk/Cable-Matters-Internal-SFF-8087-Breakout/dp/B07QFSLP6F The cards have 2 SFF-8087 ports, with each one having 4x 6Gbps SATA lanes for 8 drives at full 6Gbps speed. However, that is not the limit on drives. Each card can handle up to 256 physical disks using SAS expanders - so adding more later on doesn't need HBA replacement. The H310 comes in another version, with external SFF-8088 connections instead, to allow for an external JBOD drive enclosure to be connected. Definitely avoid the 8-port SATA PCIe cards on ebay and Amazon that have 8 actual SATA ports, but only a x1 PCIe interface. There are *some* with x4, but very few. I have one with 6 ports and x4 PCIe, and that works nicely.
  25. A really hacky/homebrew way to achieve this might be with some sort of Arduino setup that controls power to the HDD power connectors. You'd have to make a custom power cable loom... but the Arduino could be set to stagger 16 relays (or maybe 4 or 8 to bring the disks up in groups) when it's powered up? It's something I've considered myself, as I have a VM box with 12 spinning disks, and the peak power draw when they all spin up at once is... yikes. Had to carefully distribute them over the power rails. I'm using an older 1000W PSU that has 6 +12v rails. However, the thought of the wiring loom I'd have to make kind kills the idea for me as my old arthritic hands are not up to it anymore
