    Back up. We updated the Search feature a few days ago to use "Elasticsearch", not sure if anyone noticed. Searches should be better and faster. However, what happened was it crashed with "java.lang.OutOfMemoryError: Java heap space". We'll keep an eye on it and might have to adjust some settings on Elasticsearch if it happens again.

    In my opinion, about as much as you worry about getting hit by a meteorite on any given day. Yes, these are all security vulnerabilities. Are they likely? Probably not. They are proof of concepts. Are they even likely on a home server? Really doubtful. Sure, in *theory* a piece of malicious software that manages somehow to get itself and installed on your server (very remote odds to begin with) would technically be able to discern through very careful timings the contents of memory (not hard drives, but RAM). But would that information actually be useful? Once again extremely unlikely. These mitigations when push comes to shove are most for data centers because it would allow (in theory) someone to rent out time on a VM running on a server and be able to discern the data that another company has on their VM running on that same server. Intel's recommendation to completely disable hyperthreading is to render yourself safe is ignored by everyone. Personally, I disable all the mitigations for these security concerns that aren't handled via micro-code. I'd rather have the speed of my processor back to what it's supposed to be. But, if you are a member of ISIS, the Black Panthers, or (god forbid) the Mickey Mouse Club then it might not be a bad idea to use all the mitigations and also disable hyperthreading as the NSA obviously has their fingers on you. They are the ones after all who are responsible for the most malicious piece of software ever (Stuxnet)

    Very nice. Similar to what we want to do, except I was also going to back up the LUKS headers first because I'm just that paranoid 😋

    Just my 2 cents on the controller front. If using iOS, iPeng is definitely worth it. For Android I think the options are pretty miserable TBH and no where near as polished as iPeng. I used Squeezer for a while and was reasonably impressed. Then I bought Orange Squeeze and IMO it is not that great... maybe a little bit better than Squeezer but not worth the asking price IMO. However my tip is to install the Material theme/skin for LMS and then point your Chrome browser to that. It has a wonderful responsive design so works equally well on a desktop as on a mobile device. You can get chrome on Android to create a nice little icon and place it on your homescreen, which will then open a chrome-less (app like) experience. Very nice indeed 🙂

    One option - if you can get to the command line, you could type something like this: /usr/local/emhttp/webGui/scripts/notify -e "Your Unraid server is not secured" -s "I found your Unraid on the Internet without a password" -d "You need to secure this before someone hacks you" -i "alert" That will give them a notification on the webgui and send them an email (if they have that configured)

    This could be a cool add on to the web ui. While Krusader is useful, it does have its kinks. A file manage with the ability to open text docs, pics, video, etc would be cool. But even baring something that heavy, just the ability to move files or at the very least rename them would be great. Having to fire up Krusader just to rename files that I had to source elsewhere just so sonarr/radarr can then rename them again so plex can see them is a pain with how finicky krusader can be.

    For those looking for mergerfs for Unraid. I got super lucky on Reddit & the Mergerfs developer saw our plea for Unraid mergerfs. https://www.reddit.com/r/unRAID/comments/eiaq99/alternative_to_unionfs_to_merge_folders_on_unraid/ Result: He made a docker image for us....once you run, it will build a static image of mergerfs for us to use! https://hub.docker.com/repository/docker/trapexit/mergerfs-static-build docker run -v /mnt/user/some_unraid_share/mergerfs:/build --rm -it trapexit/mergerfs-static-build change /mnt/user/some_unraid_share/mergerfs_build_folder ----> an actual location on your unraid OS. After docker run completes and mergerfs is built, you would then likely move/copy it to /bin for active use!

    Tons of posts related to Windows 10 and SMB as the root cause of the inability to connect to unRaid that were fruitless so I'm recording this easy fix for my future self. If you cannot access your unRaid shares via DNS name ( \\tower ) and/or via ip address ( \\192.168.x.y ) then try this. These steps do NOT require you to enable SMB 1.0; which is insecure. Directions: Press the Windows key + R shortcut to open the Run command window. Type in gpedit.msc and press OK. Select Computer Configuration -> Administrative Templates -> Network -> Lanman Workstation and double click Enable insecure guest logons and set it to Enabled. Now attempt to access \\tower Related Errors: Windows cannot access \\tower Windows cannot access \\ You can't access this shared folder because your organization's security policies block unauthenticated guest access. These policies help protect your PC from unsafe or malicious devices on the network.

    Worst thing: system instability, dataloss if you're writing to the array when it occurs but with that said, I've run most of my servers that way for several years and it hasn't caused an issue (knock on wood)

    In disk settings make sure its set to read/modify/write (default) rather than reconstruct write. If you never changed this then its already set like that.

    The ones that you want to monitor especially are the Reallocated Sectors and Pending Sectors. reallocated Sectors are not necessarily a problem as long as the number stays small and stable, but a large number or a continually increasing number are a bad sign. Pending Sectors can be intermittent, but they are always working as they indicate there are sectors that may not be read correctly if another drive fails and a rebuild is necessary. However they not infrequently get cleared when the sector is next written so again not necessarily fatal if they only happen occasionally. The CRC count is one to monitor as it indicates a connection problem (typically cabling) rather than a disk problem, but they can still cause a read or write to fail causing Unraid to disable the drive. CRC count never gets reset - it only increases so keeping it stable is what you aim for.

    You can only rebuild as many disks as you have parity disks, so no you can't do 3 at once. Parity doesn't contain any of your data and can't rebuild any of your disks by itself. It requires data from the other disks to do the calculation. Really it's best to only try to replace them one at a time so you still have some redundancy during the whole process.

    Sorry...should've explained! I was lucky enough to have recently migrated the VM in question to a second, non-Unraid box to use as a template for another project, so I was able to simply go grab a copy of the OVMF_VARS.fd file from there. Had that not been possible, I suppose I would've grabbed a clean copy of that file from here or here, the downside being the loss of my customized NVRAM settings. I didn't notice if any cores were pegged with this happened, but I rather doubt it, because in my case there was no boot activity--I didn't get to the Tianocore logo, nor even to the point of generating any (virtual) video output for noVNC to latch onto.

    Thank you so much @johnnie.black and @trurl for all your help! I am back up and running with all my data fully parity synced and now just working on getting it all backed-up through a VM back into the cloud! While initially this all made me feel like my array was fragile, I now know that it is even more robust then I realized and have learned so much for going forward! Thanks again for stepping in and making that the case!

    I don't have active cooling on it, next I pull it out I'll see what I can do about adding some cooling. I have airflow as it's a SuperMicro chassis but it's not ducted over there. Watching things further I think the main issue could be the Mover process destroying performance when it runs. My cache drive is an M2 PCIE4 drive but when Mover fires the system becomes nearly unresponsive. Just frustrated I suppose as I bump the space limits on the 1TB cache drive moving videos around of late and performance tanks hard. I'm on 6.8 RC7 which has been stable but it looks like I'm two revs behind so perhaps there's help to be had there. I don't think I want the release 6.8 though as I think that was a kernel step backwards! Parity checks seem low as well with a speed of 113MB/s - 100+TB of space with a 10TB parity drive. Takes a day to check but other than being "slow" it doesn't impact things too badly.

    If you are parring through a GPU to a VM then it cannot be shared with another running VM. You can only use the sane GPU in two (or more) VMs if they will not be running at the same time. Hardware pass-through is always a bit of a hit-or-miss scenario as it is highly dependent on your exact hardware, BIOS, Linux kernel and KVM versions (most of which are outside Limetech's control) Until you actually try it you can never be sure if it will work for you.

    did you try to start it as mentioned in the github repo? docker exec -u nobody -t binhex-minecraftserver /usr/bin/minecraftd console For me that works, but only one time. I'm somehow not able to detach from the screen session and have to close the window which leaves me with no way to attach again. I have to restart the container to regain that ability. So i switched to not using the console command, instead I'm using the command command which works way better for me. docker exec -u nobody -t binhex-minecraftserver /usr/bin/minecraftd command <some minecraft command here without leading slash> For all commands u can visit the Arch Wiki.

    The normal recommendations are a USB2 drive and if possible use a USB2 port as they seem to be more reliable, and Unraid gains no perceptible performance gain from USB3 as it runs from RAM. 16GB is plenty of space.

    There is indeed a network conflict, because eth1 is configured to be a member of both bond0 and bond1. Easiest, delete the file "network.cfg" in the /config folder on your USB device and reboot your system. This will let it start with default network settings.

    I totally agree with the concept of using shucked drives. All of my 8TB drives are shucked mybooks. NAS / RAID drives are designed with drive cooperation in mind, things like timeout and vibration tuning. Since unraid can spin down unused drives, many of the NAS specific features aren't utilized or needed. As long as you fully test the drive before putting it into service, by whatever means gives you confidence in the drive, warranty and MTBF numbers are pretty meaningless for the quantity of drives 99% of unraid users interact with. Both warranty and MTBF are statistical constructs based on almost nothing to do with actual single drive reliability.

    To be pedantic, it can not recover at the file level, it is at the device level that just happens to contain files. Unraid and Parity is not able to recover previous versions of files. One still needs to plan for backups accordingly.

    I'll answer in a slightly different order since it makes more sense that way. Yes each disk is an independent filesystem containing complete files that can be accessed on any linux. Each disk is an independent filesystem, so each disk contains complete files. But folders can span disks, and these spanned folders are presented as network shares. 1 (or 2) parity disk allows Unraid to calculate the data for 1 (or 2) missing disk to be calculated from parity plus all remaining disks. Here is the wiki on single parity: https://wiki.unraid.net/UnRAID_6/Overview#Parity-Protected_Array Dual parity is similar but the parity2 calculation is independent and somewhat more complicated. But, parity is NOT a substitute for backups. Plenty of ways to lose files besides disk failure, including simple user error. You must always have another copy of anything important and irreplaceable. Not familiar with that solution so I will just mention some advantages Unraid has over RAID. In addition to each disk being an independent filesystem which can be accessed by itself on any linux, Unraid also allows different sized disks to be mixed in the parity array, and you can easily replace or add disks without rebuilding the entire array. The tradeoff vs RAID is exactly that each disk is an independent filesytem, there is no striping so each file can only be accessed at single disk speed instead of striped RAID where multiple disks are accessed in parallel. Writes are actually somewhat slower than single disk speed since Unraid maintains parity in realtime. There is also cache or cache pool, optionally SSDs, which can allow faster I/O, including writes which are later moved to the slower parity array.

    Aren't these software (CPU) transcoding recommendations? The i5 8400 has Quick Sync Video support and an iGPU so he can use hardware (GPU) transcoding with Plex, Emby or Jellyfin. The Coffee Lake CPUs can do 4K/HEVC 10-bit hardware transcoding. I don't know what the impact is on the CPU/GPU as I only have a Skylake CPU which cannot do 10-bit HEVC in hardware and software 10-bit HEVC transcodes brings it to its knees. For 1080p transcodes, with my 4c/8t Xeon, I have had as many as 6 going simultaneous without issue. I support 4 additional households from my Plex server and have it configured to stream in 4mbps 720p quality remotely. Everyone seems satisfied with this. Also, with the recently released unRAID Nvidia plugin from Linuxservio.io, discrete Nvidia GPUs can be used for hardware transcoding as well. I have not seen any benchmarks/specs on hardware transcoding with a P2000 Quadro for example, but that GPU does support unrestricted transcodes and, is capable of HEVC 10-bit HDR.

    The error Unknown PCI header type '127' is because the card isn't resetting correctly. This is a problem that can happen with some AMD cards. However, you have no problem with the windows VM. So why is this? Well by default there is a difference in a Windows VM and a Linux VM. The Windows VM will use a machine type of i440fx whilst the Linux VM will use a machine type of pc-Q35. I have found that you can start and stop as many VMS as you want using machine type i440fx without this error occurring. However, if you start and stop a VM using pc-Q35 then you will get this error and only a reboot will fix it. You could make a Linux VM using i440fx so then you could stop your windows VM then start the Linux one without having to reboot the server.
