  1. I didn't name a brand, but the MediaSonic was the USB 3.0 JBOD I was having trouble with. I got rid of that and built a small ITX PC with internal drives. That was about 5 years ago. I agree eSATA was more stable, but isn't an option in my current setup. I don't have any experience with Thunderbolt (JBOD or otherwise) so was looking for some input in that area. Glad your USB 3.x setup is working for you.
  2. Can anyone comment on how well DP would work with a Win 10 laptop and a 4 bay TB3 JBOD? I've used DP for quie a while, but had most success with internal drives. I did have an external USB 3.0 JBOD some years ago but it was rather flaky, often dropping the pool under sustained load (say copying a few hundred MB in one operation), which would then (as I remember) lead to needing to reboot the computer (I don't think re-plugging the USB cable or power cycling the JBOD was usually enough) and DP wanting to rescan the pool before I could use it again. I blamed that mostly on the JBOD hardware/firmware though, and not DP. Will TB3 provide a more stable pool, or am I likely to face similar issues?
  3. Sorry, I haven't been working on that system in a while. When I left it it was still a sporadic issue. I never got to the bottom of why the system would hang, nor why when that happened DP felt it needed to re-scan all 150TB. I would suggest you collect the logs Chris asks for above and submit a support ticket specific to your situation.
  4. .I don't normally keep a keyboard connected to that server and access it through VNC. I'm still trying to get a dump from when this happens.
  5. In the wiki it mentions rebooting after turning the key combination on. You should also mention that "After you're done, you can disable the manual system crash key combination by double clicking on bugcheck_off.reg." you also need to reboot for the change to take effect.
  6. Ok, sorry. They did work for me.
  7. Occasionally my server does not shut down completely. It gets to a black screen but the power never actually goes off without holding the power button. When this happens, on reboot DP goes through the lengthy re-measuring/checking of the pool(s) again. I have not determined the root cause of why the system does not shut down cleanly; I don't see anything obvious in the logs, and don''t make any software updates I can relate to this; Windows Update is turned off. Is there something I can do before shutdown to ensure DP gets stopped cleanly? Can I stop the Stablebit service then shut down? Would that help? I'm guessing not? Is it the file system itself that is marking that the pool needs re-measured. Win 7 x64 SP1 DP

  9. It isn't really about the login account(s), it is about the owner and permissions that have been assigned to each folder/file. NTFS tracks this as part of the file system. Some users and security groups are built-in to Windows with predefined Security IDs which are the same on all machines (such as Everyone), other users and groups have SIDs derived from the machine they're defined on. By default the owner and permissions NTFS assigns are at the group level and for built-in groups. If the old files were always on a single-user system where that user was in the Administrators group you should be fine. But, if any of the pool/files were exposed on a network share, multiple-account computer, copied/moved via a removable NTFS disk onto the current system, etc. then they may have stray unexpected permissions. Some software, e.g. where security is important, may also create files with special permissions. I found NTFS Permissions Reporter (http://www.cjwdev.com/Software/NtfsReports/Info.html) useful in tracking down files/folders that were not set with the default permissions and inheritance.
  10. I just did this, no problem. You should just be able to install DP, migrate or buy a new license, attach the drives and DP should recognize the pool. Someone else may know a few caveats like perhaps if you have complex duplication, placement, and balancing rules.

    Well it looks ok on my box now. Maybe something changed between *.848 and *.852. Gremlins.

    My Storage Server

    I bought the Q30 including the mobo, raid card and power supply from them. They list a few sample configurations on their site, and have a configurator for more choices, but when I dealt with them they were super flexible in working with each clients' specific needs. The configurator can be a starting point but then you can order off the menu. In my use case I wanted a different CPU than what they had on the configuraator; they could not source the specific one I asked for but understood my requirements and suggested an appropriate alternative they could source. You can check out these articles if you are not familiar with storage pods; https://www.extremetech.com/computing/178757-how-to-build-your-own-180tb-raid6-storage-array-for-9305 https://www.backblaze.com/blog/open-source-data-storage-server/ or search the web for something like "backblaze storage pod" and maybe add "open source" if you really are interested in just acquiring a case from a metal shop and not all the internals. For some history as I understand it; 45Drives was an early supplier to BackBlaze but is no longer. I think BackBlaze is up to version 6 or higher of the pod. Around version 4 or so, BackBlaze switched to BackupPods.com and possibly others as suppliers of the pods. However the pod designs are open source and can be bought and put together from a parts list if one desires. I needed something that arrived working and was not a server build learning experience, so I bought a system assembled and tested sans drives. I then just dropped my drives in, installed Win 7 and DP and was basically ready to go. Most drives were moved from some other computers, one of which had been running DP, and I added a few blank drives, so I did have to move some files around to get them into the new pool and duplicated properly. http://www.45drives.com/ https://www.backuppods.com/ http://protocase.com/products/electronic-enclosures/45drives-storage-pods.php My perhaps faulty recollection was that 45Drives wouldn't necessarily sell you all the nuts and bolts and individual parts one by one like at Radio Shack of old but would be very flexible in putting together (or leaving out) the major electronic components that go into a server to a clients' needs, and that BackupBods was the opposite on either ends of that;.they would either sell you a completely built working machine with all the drives and little customization, or they would sell you all the nuts and bolts and individual parts a la carte to assemble yourself. I'd contact both companies and explain what you are looking for. (metal case, metal case with backplanes, etc.) Protocase is the metal fab shop for 45Drives, so if you really are just interested in the chassis and not the backplanes, etc, you could contact them. This info may have changed in the past 1.5 years. Cheers, David

    Sort Pools by Name

    OK, I see that now. But when I open the UI, how does it decide which pool to display the graphical info for first? I think that is what threw me off. it always seems to default to displaying the graphical info for the second of my two pools on the popup list (it may be the first or last created or something) I guess I would expect it to not just sort the popup list but also either default to displaying the detailed pool info the first item in the popup list (my preference), or the last one displayed when the UI was closed.

    Read and write speeds probably aren't that great, especially from the HighPoint card, but luckily most of the time I don't need them to be. In a quick unscientific test right now copying a 9GB file between two drives (mount points outside the pool) averaged 130MB/s. Copying that file into the pool (eg, from one of the 10TB drives into the 142 TB pool) averaged about 90 MB/s. I've seen some tasks run a lot slower though, like 30MB/s. I'm not sure what my expectations should be in this area and haven't been geeky enough to learn to benchmark and twiddle, but it certainly isn't performing at 600MB/s headline speed of the 6Gbps SATA. Perhaps I'll look into that sometime, as I would like the task that measures the pool organization of the large pool to run more quickly, as it takes a half a day or something and leaves the system very sluggish while it is happening.

    My Storage Server

    This is the machine I use Stablebit DrivePool on. It is not strictly a "server" as it gets used for workstation tasks as well and thus has a desktop, not server, OS. Case: 45Drives Storinator Q30 OS: Windows 7 Pro 64-Bit CPU: Intel Xeon E3 1275v2 MoBo: SuperMicro X95CM RAM: 2x8GB ECC GFX: NVidia GeForce GT 710 PSU: Corsair HX750i OS Drive: SanDisk X300 128GB SSD Storage Pools: 142 TB: 10x 4TB (WD40EZRX) 14x 6TB (WD60EZRX) 4x 8TB (WD80EFZX) ~ About 3.5 million files (7 million with x2 duplication) 18.2 TB: 2x 10TB (ST10000VN0004) ~ About 155,500 files (311,000 with x2 duplication) * Pool sizes as reported by DP. Drive sizes as marketed. Both pools configured with x2 full pool duplication. Misc Storage: 750 GB (WD7500BPVT) HDD Controller card: HighPoint Rocket 750
