  1. But then you could:

    1. Attach USB disk and add to the Pool;
    2. Remove one HDD from Pool (through GUI);
    3. Replace that HDD with a big one and add that new one.
    4. Remove USB HDD from Pool (through GUI);
    5. Depending on size and duplication, you can do the other three all at once or one by one.

  2. That it says your drive is full is strange and some screenshots might work.

    Have you set x2 duplication? In that case, two duplicates are stored on the 4 HDDs and no duplicate is stored on the same HDD. So you should be fine with the failure of one HDD. There is no reason, from that perspective, to use a 2x2 config (in fact, it becomes riskier in the sense that if you have 5TB of (unduplicated) data, DP can recover from 1x4 HDD to 1x3 HDD, using 10TB out of the 12TB remaining. In a 2x2 config and one drive failure, there is no recovery until you replace the faulty disk, which you would do anyway but until it arrives you would not have x2 duplication in full and I would consider switching off the machine until a new drive is available. I have a 2(Pools)x3(HDDs) config but ensure that each Pool can miss a drive.)

    That may change, depending on the backup software used, if you want to perform a backup as well and ensure only one duplicate is backed up. In the case, you might think of Hierarchical Pools. The search function should point you to some threads where I explained such setup.

  3. I believe I have the IBM M1015 but called Dell H310. I think it is the same card and I use it in IT/JBOD mode. No issues whatsoever, it drives 6HDDs and I got two more ports available.

    The only thing I can not get it to do is allow for the drives to spin down.

  4. Are you able to add additional drives to the machine first before beginning file operations? It is going to be a somewhat lengthy process anyway unless you have a full backup, then it is still going to take time but it'll be a bit faster and easier. Do you use Server Backup, I am asking because of the 2TB Server Backup volume limit that you can get around a bit cumbersome but it does work.

    Yes, I would upgrade to the latest version but that is unrelated (except for dealing with the 2TB limit) to the issue at hand IMHO.

  5. Well, not incredibly.... ;)

    But it would have been more efficient if, for instance, you set Drive limit options in the Drive Usage Limiter. Removing drives is a serial / single "thread" I think. I don't know how one could have known this easily.

     

  6. Pools behave as if they are regular NTFS formatted volumes. However, any software that uses VSS (which many backup solutions do) is not supported. I don't know Crashplan so couldn't say. Having said that, you could backup the underlying drives. If you use duplication, then Hierachical Pools can ensure that you only backup one instance of the duplicates.

  7. I think you mean errors in the Event Viewer? Anyway, I can confirm that running WSE2016, Server Backup runs just fine with me. I also include some of the underlying Pool drives (not the Pool itself, that won;t work and should give errors such as above).

    I don't know, Christopher might know. What I would look at, again, is the Server Backup setup and really ensure it is not trying to backup the Pool. Can you find out what Disk 8 and HarddiskVolume22 is?

  8. No worries.

    You do want to edit the list (don't do a new post, edit the existing one). Prior to step 2, one should stop the DrivePool service. After step 2, restart the service (or reboot). This is not trivial because while you are moving files into a Pool, DP may start to rebalance.
