  1. Not sure how the transferspeed would be higher and if you were to copy files to the Pool then, by default, DP would write to the drive with most free space available...
  2. In principle, yes. Not sure how to guarantee that they will stay there due to rebalancing, unless you use file placement rules.
  3. No, you only need a license on Server and then allow PC and laptop to access a share that points to the virtual disk DP makes for you. On Android, no clue.
  4. You could use Hierarchical Pools. Say you have disks A, B internal and C is the external one. You can then: 1. Create a Pool Q consisting of A and B, no duplication 2. Create a Pool R consisting of C, no duplication (*) 3. Create a Pool P consisting of Pools Q and R, x2 duplication. However, I don't think there is a good way to deal with temporarily removing drives. AFAIK, if you then (physically) remove/disconnect drive C, DP will put Pool P in read-only mode. May be what you are looking for but I'm not sure that will always work out well. Moreover, is that a USB connected drive? AFAIK, using USB-connected drives is not considered best practice and IIRC, it has led to problems, including data loss, due to connections over USB sometimes dropping for a bit (which I think is still within spec for USB). (*) you could also create Pool P with Q and C, so without the intermediary step of Pool R but I think it makes it a bit harder to manage when removing/adding.replacing drives.
  5. I think https://stablebit.com/Contact
  6. Then perhaps you need to follow Terry's instructions on the other underlying drives first.
  7. Actually, I think you are right. Once DP has worked-out which files should go where (I think that happens when DP status bar says "building bucketlist"), it should at that point be easy to see if there is space enough. I would still want DP to go ahead, because it has to happen anyway, but perhaps send out a mail or somesuch indicating that more space is needed. Then again, it is coding for something that is, I think, rarely an issue. Once you need to replace a drive, insert on of at least equals size. That is, I think, by default what most would do anyway. I run DP one a WSE2016 server BTW.
  8. Yes. I think there is a stting in DP to try to recognise the Pools after Bitlocker has been started or somesuch.
  9. Actually, once a drive is lost, it would take quite some time to determine how much would be needed to re-establish the required duplication. DP would not have been aware or remember what was stored on the lost drive. The first step is called re-measuring (try it). And yes, as a result of that, DP might be able to give a recommendation on how much, if any, additional storage is needed. But practically, if you know the size of the lost drive, then all you need to know is: how much data was on it and how much do you have available now. Your math does not work out BTW. After the failed drive, you have 4TB of duplicated data (using 8TB) and 4TB of unduplicated data and you would need a 4TB drive.

    DIsk duplication

    If you want to replace, the best way, IMHO, is to: 1. Add a new drive to the machine and Pool 2. Remove the faulty drive through the GUI of DP 3. Let DP do its magic (may take a while) 4. Remove the faulty drive from machine.
  11. Sorry, I am at loss here. Can you access the backup folders on the underlying drives?
  12. But imagine you are going to write a new file to the pool. How would DP know whether it will have to write two or three duplicates? That is not deterministic. Put otherweise, imagine you have two folders only, one is x2 and the other is x3 duplication and 3TB of (gross / real) space available. What should DP show? 1.0 or 1.5TB free?
  13. There is always this: https://wiki.covecube.com/StableBit_DrivePool_Q5510455
  14. No. If, and only if, the entire Pool had a fixed duplication factor then it *could* be done. E.g., 1TB of free space means you can save 0.5TB of net data with x2 duplication or .33TB with x3 duplication etc. However, as soon as you mix duplication factors, well, it really depends on where thre data lands, doesn't it? So I guess they chose to only show actual free space without taking duplication in mind. Makes sense to me. Personally, I over provision all my Pools (a whopping two in total ;D) such that I can always evacuate the largest HDD. Peace of mind and coninuity rules in my book.
  15. Not entirely but pretty sure DP will not be able to tell whether there is enough space, nor how much will be available afterwards. But yes, if the Pool had over 8TB free prior to the failure of one 8TB drive then there should be enough space available (probably rare exceptions excluded).
  16. I must be missing something obvious. The two 7TB drives, those are G:\ and L:\, no? I am tempted to say you simply have an actual 14TB HDD in your machine You see, with me (and AFAIK others), DP Pools show up in disk management as 2TB HDDs, regardless of their actual size. If in disk management you right click -> Properties -> Hardware, in the list you then get to see, do you see Covecube Virtual Disk as one of the names? If you write a file to F:\, does that file appear on G:\ and\or L:\ somewhere within the hidden poolpart.* folders on G/L? Do they have hidden Poolpart.* folders?
  17. Wait, you tried to format the F:\? The Pool? And that worked?? Just uninstall DP then.
  18. @OrozarBE: No, I don't think you can use the ordered placement pluging to direct duplicates that way. Hierarchical Pools will allow you to do that though. @OP: This is weird, and I wouldn't know how to help with this for sure. I *think* it is caused by the fact that the external drive is larger than all the rest of the Pool. To be sure, you can only store 3.6TB of duplicated data (net basis, 7.2 total) and 0.9TB of that external drive will not be used for duplicated files. I suspect that is where the issue lies. DP will try to maximise storage capacity but will never be able to use that part. If you could attach another drive to the Pool, even if just a 1TB HDD, then I suspect it will resolve.
  19. Yes, DP not need/use the drive letters of the underlying disks.
  20. When you click on F in drivepool, where exactly do you click? Not sure how you are going about here but without somde detailed info on what DP looks like there is no way I can think of to help. I would consider though to (and assuming there is NO data on the actual HDDs): 1. uninstall DrivePool, reboot 2. Format the actual HDDs, reboot 3. install DP 4. Add the two HDDs to a Pool according to the instructions.
  21. Could be any of those things, without more information it is impossible to tell though. Just a heads up: Is the external drive connected through USB? AFAIK, USB-attached HDDs are not advised by Christopher and IIRC there are a few threads/posts here from people who got the Pool messed up due to USB-attached HDDs. The issue is, I think, that USB connections may drop sometimes.
  22. Well, you got it. I would also physically disconnect the pool drives before installing the os, just to be sure you don't mess up during OS installation.
  23. If DP does not show any drives being pooled, then perhaps you do not have a pool at all? Could you show screenshots Explorer just to show which drives Windows sees and DP?

    Not auto-balanced

    Seems fine with me. As I understand it, you want to have files that belong together to be saved to a single HDD if possible, no? In that case, this works. Once the HDD is 90% full it will continue writing new files to the other HDD so you may have a bit of a break there but after that new files will be written there. You might want to consider using duplication. Now, if HDD 1 fails, you loose everything (unless you have a backup solution which is always highly advisable). With duplication, you have at least a bit of protection.
