    License Issue After Update

    Without having access to the License database at Covecube, the only thing I can suggest would be uninstalling the current version, re-installing the last Beta version you had installed previously, activating the license in it (if necessary) and then de-activating the license right after. If that works, you'd then be able to uninstall the Beta and re-install the new version clean with a new activation.

    DrivePool + Primocache

    I recently found out these two products were compatible, so I wanted to check performance characteristics of a pool with a cache assigned to it's underlying drives. Pleasantly, I found there was a huge increase in pool drive throughput using Primocache and a good sized Level-1 RAM cache. This pool uses a simple configuration: 3 WD 4TB Reds with 64KB block size (both volume and DrivePool). Here are the raw tests on the Drivepool volume, without any caching going on yet: After configuring and enabling a sizable Level-1 read/write cache in Primocache on the actual drives (Z: Y: and X:), I re-ran the test on the DrivePool volume and got these results: As you can see, not only do both pieces of software work well with each other, the speed increase on all DrivePool operations (the D: in the benchmarks was my DrivePool letter) was vastly greater. For anyone looking to speed up their pool, Primocache is a viable and effective means of doing so. It would even work well with the SSD Cache feature in DrivePool - simply cache the SSD with Primocache, and boost read (and write if you use a UPS) speeds. Network speeds are of course, still limited by bandwidth, but any local pool operations will run much, much faster. I can also verify this setup works well with SnapRAID, especially if you also cache the Parity drive(s). I honestly wasn't certain if this was going to work when I started thinking about it, but I'm very pleased with the results. If anyone else would like to give it a spin, Primocache has a 60-day trial on their software.

    Switch from DriveBender

    A - Yes, it is - any OS that can read the file system you formatted the drive with (assuming NTFS in this case) can see all it's files. The files are under a "poolpart..." hidden folder on each drive, fully readable by Windows. B - Yes, it will work with Bitlocker. This is a quote directly from Christopher on these forums: "You cannot encrypt the DrivePool drive, but you CAN encrypt the disks in the pool." (Link)

    Existing drives, how to convert

    Small sidenote from me on the drive letters, since I changed to a defragmenter that requires letters assigned and I hate to see all the pool drives in Explorer. I followed the instructions from this article to selectively hide the drives I wanted. They can still be accessed by Win-R (run dialog) and typing them in there. Not sure if it still works in 8/10, but I'd wager it does. It was the perfect setup for my server.
  5. I use BitDefender, but I set the actual DrivePool itself to excluded (no scans directly on the DrivePool letter or directories). I do this for compatibility, since any files I add to the pool have already "landed" and been scanned on machines on the same network. In other words, if you don't download/save files directly to the pool from the web, you don't need to run real-time scans on the pool. Just have a separate machine or directory that IS scanned, which takes all new content from the web first, and you're pretty safe. I also never run programs directly from the DrivePool. I instead copy them to the C: drive of the machine I plan to run them from. That copy is protected by the AV software, and so anything coming off the Pool is re-scanned then. From that perspective if you can set exclusions in whatever AV you are using, you can pick whichever you like, Defender included. Using this technique and a tuned network layer, I've managed to get my storage server to take network writes to the Pool at around 112-115 MB/s (fully saturated Gigabit). No AV scanning, full speed.

    Existing drives, how to convert

    DrivePool will work (as you found out) with drives that have existing data on them. To get the data moved onto the pool so it isn't just sitting on a drive, give your DrivePool drive a letter and simply move (cut/paste) the files over to it. It'll start distributing those files to all drives in your pool, according to whatever balancing policy you setup - the default is evenly between all pool drives. Any files that started and ended up on the same physical drive just use the NTFS "move" operation, and the MFT is simply updated instantly (like moving a file between folders on the same drive). Once you have just the pool directory left (which is hidden on each pool drive) and no un-pooled files on them, you can un-assign the old drive letter if you like. I prefer to mount them as folders under my C:\Pool_Volumes folder, so I can quickly and easily get to all the drives outside of the Pool.

    Current Pending Sector count 1?

    Editing my post for a bit more clarity: You can use duplication and then simply take the drive out of the machine, and revert duplication to x1. However according to the DrivePool feature list, when you remove a disk from the pool via the software options: Provided you have enough available space on other disks in the pool, then Christopher is correct in that a removal will transfer all files to other disks prior to removing the drive you wanted. I'm not sure which option is faster. Either should work. Christopher's advice is probably the best you're going to get.

    Current Pending Sector count 1?

    Ask someone what the term "spinning rust" means in 20 years and they may look at you funny. Let us know how it goes WickedLlama!

    Current Pending Sector count 1?

    Yep, basically any secure-erase utility writes whatever pattern you want to the sectors. The more advanced will do multi-writes, toggling bits as they go. i haven't had to use one in a while, but it should do the trick here. I usually retire drives when sectors start to go bad, just as a good disaster-preventative practice.

    Can't install oculus games to pool

    Good to know, learn something new every day! Now that is an awesome idea.

    Current Pending Sector count 1?

    If the sector has no data in it currently, a secure erase of all empty sectors on the drive would work. Some tools available to do that can be found here: https://www.raymond.cc/blog/make-your-recoverable-datas-unrecoverable/ If it has data in it, simply finding the file via a block map tool and deleting it (removing it from the MFT) would mark the sector empty, allowing you to then do a secure erase which would force a write to it.

    Can't install oculus games to pool

    Drivepool to my understanding uses a proprietary file system, the CoveFS. It should be fully compatible with NTFS standards, but Oculus is trying to create a temp folder structure, which is where the error in your output comes in: The technical why of this error isn't something I can explain; I'd think Alex or Christopher could. You may be right about Oculus updates, in which case I'd suggest creating that "tmp" directory yourself by hand, which might solve future issues. The symlink you made may cover it however, since the OS generally doesn't care about symlinks vs hardlinks for normal file/folder structures. Do you have a game on Oculus that would typically install, and then need an update after, like perhaps an optional DLC or addon that you could test after moving/symlinking it's main install? That might be a good test, until you get a better answer from the team here.

    help with standby

    Are your parity drives the same make/model as your data drives? Some firmware features aggressively attempt to spin down drives (park heads/sleep) while some are more relaxed. I had to patch my WD Reds since they were parking heads after just 8 seconds of inactivity, raising the load cycle count unnaturally in a NAS.

    Can't install oculus games to pool

    Install the game to your Oculus drive, move the folder to your DrivePool drive, create a Symbolic link on the Oculus drive where you moved the folder from that points to the folder on the DrivePool drive. It's worth a try, since I doubt Oculus requires hardlinks for installed software. If you don't want to do it by hand, you can try software like Junction Link Magic.

    Error: Not enough data.

    Updated the ticket today. I was rather... verbose. Sorry! What I added may change what you guys are testing on the ticket, and where I go with my future troubleshooting. Thought you'd want to know. Trying not to waste your time when what I'm seeing changes.
