  2. Meltdown / Spectre Benchmark

    Thank you for your feedback. This should be fixed in 1.0.6592.33749, which I've just put up now (see link in original post to download it). I've tested with 390.65 with a Geforce 1070 Ti running on a Haswell platform and I'm not seeing anything like that. The benchmark doesn't do anything to block other system calls while it's running, and it doesn't elevate its own priority in any way. Other processes in the system should continue to function normally while the benchmark is running. In fact, the OS Calls / Second that is measured is a combined count of what the benchmark is doing combined with all of the other apps in the system. Maybe certain platforms are more sensitive to the high loads that it's generating? You can try to reduce the number of simultaneous threads in Options (little gear). I've seen different numbers quoted, but the truth is, it's workload dependent. If an app is not making many system calls, then it will be affected less, and if it's making a lot of system calls, it will be affected most. This benchmark is measuring the Operating Systems' maximum user / kernel transition rate. With the new patches, every time that transition happens the TLB (translation lookaside buffer) is flushed on the CPU. The TLB is a super fast lookup table that translates virtual memory addresses to physical ones. Without it, the CPU has to go to the RAM to perform that translation (which is much slower). Added some additional text in 1.0.6592.33749. Anecdotally, I've been playing around with this benchmark on my Hyper-V machine, and I'm seeing huge performance differences on the VMs toggling the patches.

  4. Simple Newbie Question

    Thank you for your reply Christopher. Ok... What would be your recommendation to setup this drive array with some protection? Not that knowledgeable with these technologies.... regards, D.
  5. So something like this? Deactivate the StableBit DrivePool license on existing server build Shut down the system Disconnect data drives (but leave them in the box) Power up Install Server 2016 (wiping C during install) Do basic config of new server install and shut down Reconnect existing data drives Power up and ensure data drives show in Disk Manager Create new mountpoints for data drives Install/Activate the StableBit DrivePool (And Scanner) software for new build Let it to "automagically" (automatically) recreate the pool on this new build Continue with rest of server config. Anything else I should be aware of? Sonic.
  6. What if I wanted to upgrade the OS on servers that use Drivepool?

    That should be good. You can add/change the mount points at ANY time. StableBit DrivePool may display these, but the software doesn't actually use them. We use UNC/device/kernel paths to access the drives, and these never change (at least without rebooting)
  7. Best practice to access pool data under WinRE

    You wouldn't. It's not supported. WinRE is a modified WinPE environment. And we have tried setting up a WinPE environment with just DrivePool. It doesn't work. It doesn't like the drivers. So you need a full installation to access the pool properly. So if you're backing up to the pool, then this won't work for a bare metal restore. That's fine. We hide them to make things easier (eg, harder to eff up) But remember that the contents will be spread between the disks, so you may not have all of the data on one disk
  8. Meltdown / Spectre Benchmark

    I'd answer, but most of this needs to be answered by @Alex, I think. But the first two, I think are "expected". As for the rest, I'm not sure. And for the most part, normal usage may not be affected drastically. Browsers are CPU light, but heavy on RAM, for instance. Games, and some processes may be affected, and the values may be "real world" depending on the program. But running as Admin may be a (shitty) stop gap to regain performance.
  9. Drashna, I found this older thread where I asked you for some specifics on migrating disks from one server to another. I am back for more confirmation on what to do with existing disk sets (16TB in Server A and 6TB in Server B) if I plan to install a new OS. Within Q1 2018 - I want to upgrade both of these servers from Windows Server 2012 R2 to Server 2016. I have read a bit about "in-place" server upgrades - but I think I will start from scratch and install the OS clean on each - meaning I will need to power down the storage disks - disconnect them and then power them back up when Server 2016 is installed and ready to go. On both of my systems - I am using drive mountpoints to ensure each Pool - is displayed via a single Drive letter (D:\ in this case). Using your suggested procedure: Deactivate the StableBit DrivePool license, if needed. Shut down the system physically remove the drives Put the disks into the new system power on the new system install and activate the StableBit DrivePool software on the new system Wait for it to "automagically" (automatically) recreate the pool on this new system What other steps do I need to do (and when) within this list with regards to mountpoints etc on the drives without upsetting any data on them - and hopefully being able to recreate the pool and get them back on the network with minimal downtime? Appreciate your insight as always. Cheers! Sonic.
  10. What would be the most natural way to access pool data within a Recovery Environment? I have a simple x2 file duplication pool (WHS2011) made of two identical GPT formatted disks. I save my client as well as the server backups to the pool. Recently wanted to perform a bare metal recovery of the WHS2011 and was surprised it wasn't that straightforward. Using the WHS2011 recovery flash drive it was impossible simply because it just offers the system recovery wizard. Of course it's unable to locate the backup files automatically so it offers manual selection through a file open dialog box. I can see that both pool drives are recognized correctly (total and free spaces are correct) and as expected I can't see the hidden PoolPart.* folder so am unable to access the files stored in the pool. Booting from the WHS2011 installation disk as well as using more recent WinRE versions I have access to a DOS shell so I can change the attributes - unhide the PoolPart.* folder on any of the two disks and thus access the server backup files. Now what would be the "correct" way to access server backup files from within a Recovery Environment? If I unhide the PoolPart.* folders on (all) pool drives can I leave them unhidden? I actually have the physical drives that compose the pool hidden so in Explorer I see only the virtual Pool disk drive. Don't need to access the disks "outside" of the Pool. Thanks in advance. Cheers.
  11. Meltdown / Spectre Benchmark

    Having tried this benchmark on my patched Win10 Pro 64Bit 6700k - no overclock - just xmp applied to the ram there are a few issues 1. disabling Spectre - actually disables Meltdown as well after a reboot 2. approx half way through the benchmark the screen goes blank and then corrupts (monitors go into standby) - most times it does come back - sometimes it does not - needing a hard reboot to get the machine working again. Possibly the nvidia drivers (390.65) which i think are the ones patched for M & S? - You can see the drop in capture3 when this occurs - in this case it came back as i was able to get the screen capture. 3. With both patches enabled i get a score of approx 8.5m - with both patches turned off i get approx 83M - is this realistic as i thought the effect was approx 30% from what i read in the press? Or is this a specific test - worst case if you do say a lot of database work?? 4. Maybe you need to make it clearer on the interface that a reboot is required to change the enabled/disabled state of the patches prior to clicking on them? Like the idea of this tool so thought i would report the issues i am seeing
  12. Drives not appearing in "This PC"

    I had a crash and had to reinstall Windows 10. After the installation my 2 Cloud Drives didnt show up in the usual "This PC" section where all my physical and virtual drives are. The only thing I have done (besides reinstllation of the OS" was changed the size of both drives from 10 TB to 100 TB to which DriveCloud informed me that it couldnt change the volume size and that i would need to do that manually. I tried resizing the volumes using a partition manager with not success. I ended up destroying one of the drive but have one left with7.40 TB of data on it. It has finally showed up in This PC but when trying to access it i get a message popup telling me the drive needs to be formatted. What have i done wrong and how can i fix it? Cheers

  14. Box Account, uploading FOREVER, cannot STOP/PAUSE

    Well, as for the CPU usage, I/O access is "expensive". So if you had a LOT of drives, (and 44 is a lot!) that could potentially bog things down, especially if you have a lower end CPU. And yeah, even with it paused, it's still downloading from the provider, and it's still reading and writing data locally. So, a lot of I/O still. As for the script, no, that's fine.
  15. Simple Newbie Question

    You mean adding a RAID5 array to StableBit DrivePool's pool? As long as it shows up as a normal disk, absolutely! And any "hardware" controller will do this. (show up as a normal, physical drive, that is) StableBit DrivePool doesn't do parity (RAID5) itself. It's more like a RAID10, but even that's not quite accurate. That said, you can add and remove drives at any time. And unless one or more drives is very full, it shouldn't need to rebalance (redistribute) the data. So again, StableBit DrivePool doesn't do parity, at all. It's not a RAID5, but closer to RAID0/1/10, or a JBOD. And this depends on what you've set the duplication to. But you can use other software like SnapRAID to add parity protection, if you'd like. Unfortunately, I don't see that email or ticket. Where did you send it at/to?
  16. Box Account, uploading FOREVER, cannot STOP/PAUSE

    Chris, Thanks! I'll check this out soon. For now, I just removed all the BOX drives and it seems to have made everything happy again. It could have also been causing a LOT of pool inconsistencies (where formatting or just purge and re-add was the only way to "fix" the Drive Pool issues with these cloud drives). I cannot be certain, as I never saw "I did this thing" then Drive pool went wonky. So, I have not posted about it. For now, I have been using ONLY Google Drive and removed ALL other drives. That means my space dropped quite a bit, but I see with only 11 drives (as few SMB as well), my processor use has dropped from being pegged to 100% for DAYS on end, to rarely getting over 10-20%, and when it does, it is for seconds. I think in total, just to push things, I had 44 drives in there. That was unhappy. I am thinking even with the UPLOADS paused, there was something else going on all at the same time? Pinning data maybe? For now, with the 11 drives, I have not had to run my script (which I never uploaded to you as I've found issues when the processor use is HIGH...the script fails in a strange way). Maybe I should post it privately to you just so you can see what I was trying to accomplish (and seemed to help quite a bit)? Thanks!
  17. Simple Newbie Question

    I'm new to this so here goes... Running Plex buying 5 Drive Bay StarTech S355Bu33ERM USB 3.0/eSata Enclosure with UASP. https://www.newegg.com/Product/Product.aspx?item=N82E16817707373 Plan on putting 12TB Drives in however only a few at a time. My question(s) 1. Can Drive pool function over a Raid 5 configuration? 2. If I start of with 1 Drive, can I add later and build raid 5 over time or will the array have to be rebuild? (Just looking for a bit of protection) Sent an email to support. It's been a week. Kind of don't want to wait. Thank you in advance.
  18. Meltdown / Spectre Benchmark A free standalone tool to assess the performance impact of the recent Meltdown and Spectre security patches for Microsoft Windows. Download: X86: Meltdown.Spectre.Benchmark_X86.exe X64: Meltdown.Spectre.Benchmark_X64.exe System Requirements: Windows 7 / Windows Server 2008 R2 or newer .NET Framework 4.5 or newer Visual C++ 2013 Redistributable (most systems should already have this) Feel free to share this tool, updates will be posted to the URLs above as necessary. (both files are signed with the Covecube Inc. certificate) FAQ Q: What is Meltdown / Spectre? A: Meltdown and Spectre are the names of 2 vulnerabilities that were recently discovered in a range of microprocessors from different manufacturers. In order to protect systems against exploitation, Operating System and hardware firmware patches will be necessary. Unfortunately, these patches will inflict an overall performance degradation, sometimes a severe one. In general: Meltdown is Intel specific and does not affect AMD processors. It's mitigated using a Windows patch from Microsoft. Non-elevated processes will be affected most by this patch. Spectre requires a Windows patch and a CPU microcode update from your motherboard manufacturer (in the form of a BIOS / firmware update). For more information on these exploits, see Wikipedia: Meltdown (security vulnerability) Spectre (security vulnerability) Q: What is this tool for? A: This tool allows you to: See if your Windows OS is patched for Meltdown / Spectre and if the patches are enabled. Benchmark the OS in order to get a sense of how the patches are affecting your performance. Enable or disable the Meltdown / Spectre patches individually in order to assess the performance difference of each. Observe the number of system calls that your OS is making in real time, as you use it normally. Q: How does the benchmark work? A: The benchmark will measure the peak rate of user to kernel transitions that the OS is capable of using all of your processor cores. This is not the same as measuring the CPU utilization or memory bandwidth. Here, we're actually measuring the efficiency of the user to kernel mode transitions. While the patches may affect other aspects of your system performance, and the performance degradation is workload dependent, this is a good way to to get a sense of what the performance impact may be.
  19. Icy Box IB-3810U3 JBOD + Drivepool

    Yeah, I definitely understand that. However, adding a utility to do this wouldn't be a small/simple thing, and we're nor really ready to add something like that, right now. In the future, maybe. it's bee something that I've been pushing for, for a while, as well. Otherwise, "enable duplication on everything", and it's not a great answer, either.
  20. Down sizing my server

    Okay, glad to hear it, then! I just wanted to make sure that you were aware of this beforehand. it's easier to change specs before you buy and build the system!
  21. Disks don't turn off in Windows 10

    I hope, that nobody is thinking the problem is solved now...
  22. x-post Hi Christopher, I am aware of the command line options, but deem it an ugly solution since the reason for using Windows for NAS is to get away from the cmd line hassle Since Drivepool already scans the filesystem like all the time, I would like to propose creating .txt files as place holders every time Drivepool moves a file. BR, A

  24. Down sizing my server

    Good points but this CPU should be more than what I'll use it for. khr2011 is showing stats for Emby and this CPU. "I tried Emby with different videos on the same DS918+ and it transcodes 10bit 4k HEVC 60Mbps to 1080p h264 30Mbps perfectly with 25% processor usage" https://forums.plex.tv/discussion/296528/ds418play-hardware-transcoding. It will mostly be a DLNA music server, file server and a backup end point with the occasional transcode of 1080p to our Ruko in the bedroom. . The FireTV direct streams everything I have.
  25. Can´t access my HDD on another PC

    If it is taking a while to load the permissions, then it sounds like it may be a network configuration issue. On both systems, try running this and rebooting (from an elevated command prompt) netsh interface tcp set global autotuning=hoghlyrestricted And in device manager, for the network adapter, try disabling any feature with "checksum" or "offload" in the name.
  26. Down sizing my server

    Just be careful. A low power CPU is, well ,low powered. You may have issues with transcoding still. Or multiple streams. You'd want to direct stream, as much as possible.
  27. List of missing unduplicated files when drives crash ?

    For the list stuff, check out this thread: https://community.covecube.com/index.php?/topic/746-drive-must-have-died-is-there-a-way-to-tell-what-was-on-it/
  28. Device Timeout Fix?

    Not just "no cables", but it also doesn't include a bracket, so you'd want to mount it somewhere in the case, and run molex power. Rather than using a PCIe port. Is this disk cloned? And are you running this in a VM? Also, run the StableBit Troubleshooter, and use "3398" as the Contact ID for it. Make sure "collect system info" is enabled/checked.
