  1. For backups, once a week I shutdown all of my VMs which are on my cache drive. Then I create a read only BTRFS snapshot, immediately start the VMS back up and then backup up from a samba share of this read only snapshot. This keeps the VMs in a clean state but minimizes the amount of downtime. The snapshot is removed after the backup is complete. Anyway, this works alright except the samba share for the snapshot will not exist if unraid has been rebooted causing the backup to fail. It seems like the shares are recreated on startup or something and since the snapshot doesn't exist when this happens the share doesn't work. To fix I create the snapshot and then just toggle a user account from read to read/write and back in the SMB share settings. But I don't know how to do this in the command line to assure the backup works every time it reboots. So my question is can I change a user setting somehow through the command line or otherwise restore this state?
  2. I'm not really an active user there, and it seems I've forgotten my login! (It also seems the forum was going to shutdown but might now migrate instead) Anyway, there wasn't really a thread but I recall there being a request mods forum and there were at least 4-5 guys (probably more) that just did custom bios mods in return for donations.
  3. While I haven't used this plugin (my gvt-g experiments were with a custom kernel before this became a plugin) I have something to add regarding aperture size issues. When I was testing things out, I paid a guy in win-raid forums to build me a custom motherboard bios that exposed the aperture size. Most boards bioses have a lot of common code so it's usually just a lazy UI choice what they do and do not show. That allowed me to get access to the higher resolution/vram modes. In theory I could have probably done the bios mod myself, but I had none of the tools or familiarity with them so it definitely would have taken me awhile even with the guides on win-raid. So I just donated to one of the modders on there. I believe it might also be possible to manually tweak these hidden options through the efi shell as well but I didn't investigate that much. It's definitely true that most bioses lack the aperture adjustment setting by default though and motherboard manuals available online often don't even have enough detail to determine this without buying the board. My board was a ASUS z370 prime a ii, but again...it does not have aperture adjustment by default, only with a modded bios. I lost interest in GVT-g when Intel abandoned it personally.
  4. I have a VM that is using outdated software. I'd just disconnect it form the network entirely but I'd like to be able to install some things from my unraid shares occasionally, as well as back up to them. Is there a way to limit the VMs network connection to only certain IP addresses on the network to limit it's attack surface. I'd rather not do any of these things from within the guest, but at the host level.
  5. I have a share to a read only shapshot on the btrfs disk that I use for backups. It's created by first creating the snapshot, then just going to shares in the web admin and setting permissions on the snapshot as normal. If the shapshot is deleted and recreated the permissions persist and everything is fine. However, if I reboot the server or change the permissions of any share then it's broken. I need to go in an manually update the snapshot share (and create it again first) to fix it. Typically I just toggle a user in the list from read only to read/write and back and things work again. Which I often forget to do. I know this is a non-standard config setup but I'd like a way to perform that toggle automatically in my backup user script to alleviate this problem. But I don't know if the unraid share permissions are exposed in anyway like this. I know the underlying linux permissions are, but that is not what I'm trying to change here. It's the SMB share.
  6. Some of my disks had some sensitive documents with personal info on them. The disks were not and are not encrypted. I deleted the files some time back. I'd like to assure they aren't recoverable in the case of theft, drive sales, etc. All the disks in my array are hard drives. From reading around, what I should have done was used shred to overwrite them instead of just deleting them, but I wasn't thinking that far ahead. So I was thinking that filling the empty space on the disk with zeros would accomplish the same task, albeit not very efficiently. Would something like this work? Or will unraid interfere with this in some way I'm missing? dd if=/dev/zero of="/mnt/disk1/filler" bs=10485760 dd if=/dev/zero of="/mnt/disk1/filler1" bs=1 rm /mnt/disk1/filler rm /mnt/disk1/filler1
  7. I reworked the script to instead copy and delete the original since that was a workable solution for this case. I think I figured out why shred was so effective at triggering it all of a sudden. I was using the "-u" option. If you look at the help for shred, by default that renames the file before deleting it! (rather it says it "obsfucates the filename before unlinking". I bet if I drop that option it will be OK. Good ideas on the disk shares, not sure I'll go that route but I think it could be made to work.
  8. I'd rather not disable NFS since it's solving a problem I had with samba shares. I already disabled hardlinks awhile back. Does it make sense that NFS is involved if nothing is interacting with any NFS shares at the time of failure? The share is mounted in a single VM that was not running. And actually...looking back its not even clear if I'd enabled NFS when I first had this problem. I don't use Tdarr.
  9. Well, this happened to me again today. I thought it was running the shred command that did it but that isn't involved into today's case. I believe the trigger is again a script that using "mv" to rename a file and then deletes it. I'll try removing that part of the action and seeing it happens again. The shred command actually probably performs a similar action when unlinking a file name so they might be the same type of cause. Attached are diagnostics in the degraded state. VMs seem to stay running if they were up and I actually still have access to an unassigned device share. Not 100% sure this is the only case, but the files are being changed on a share on my cache drive, with is a SSD and uses btrfs. I only have one docker, a minecraft server, and I haven't actually run it in months. I have an NFS share, not sure that is relevant but I only enabled that in the past couple months and it sort of matches the timeline of when this started occurring. But the files are being edited through samba shares, not NFS. tower-diagnostics-20220112-0934.zip
  10. This issue seems to pop up for me and I haven't seen it before. What I changed recently was I added a script that renames a file, actually a couple of times and then runs shred on it. Not sure if its the shred or the rename. The file remains in the same directory, I'm just changing it's extension. I mention this because I read another post where some one mentioned renames in the same dir related to this issue. I am using 6.8.3. I'm going to experiment with removing the mv (rename really) command.
  11. My parity drive seems like it is kind of slow, so I'm planning to upgrade it to a faster drive. But I have a number of data disks that are of a similar size. But I'm concerned I'll buy a drive that is 3.99TB and have a data disk that is 4.01TB so that it won't work. Is that something I have to worry about? I should note that my data disks are similar to the parity drive that I find is to slow so just swapping them isn't an option.
  12. Did you ever make any progress on this?
  13. Ran into this problem for the first time today. I was renaming and deleting some empty files on the cache drive when I lost access to all shares. I had a script that was adding and deleting in the same directory. I was using a samba share but the script was on unraid so not samba. I'm using 6.8.3. Weirdly (and fortunately) VMs were still running fine and rebooting appears to have restoreed everything.
  14. I'm not sure if this is the same issue since all the hardware is different but recently I was having crashes after reboots with a old AMD card, but only with the drivers installed in the VM. I didn't think it was the reset bug (although maybe in a way it is) since I'd used the card successfully for passthrough tests in the past. What actually solved the problem was ALSO passing through the hdmi audio which I had just left behind before since I didn't need it. I still don't use it but it was stable after this point.
  15. Yeah, we have the GPU drivers built into unraid now so I think we just need QEMU compiled with the right flags?
  16. Now with proxmox: I'm taking a look at that one tonight. I had no real interest in running a Windows server ever again.
  17. If you're looking for a GUI to interact with VM snapshots with today, you can use virt-manager with unraid. That's what I use and I like it a lot. Keep in mind you can't snapshot ovmf machines (that's not unraid's fault its an old bug/limitation with KVM that I'm surprised isn't fixed) and you'll need to change how the VMs are stored because their states will be lost on reboot otherwise. (unraid by default creates its VMs from scratch essentially every time it boots but it has no system to maintain snapshot information). Certainly would appreciate some tools for btrfs though, I have to go all command line with that.
  18. I put mine as "at array first start" I remember having a lot of problems with the chained directories and can't remember if I figured it out. I had to clean them all out before I got things appearing to work OK again though. I think the symlinks were messed up when the script was run to many times so it kept creating redundant ones. Its been to long since I messed with this unfortunately. If I were to improve the script I would make it better handle checking for the symlinks existing.
  19. I would like to have wireguard setup to certain VMs (and maybe some dockers but no use case for this right now) connect to the internet ONLY through a VPN like mullvad and other VMs and existing dockers connect without the VPN. I read the thread but I was a little confused about whether that was possible by the end. Basically I want to offload VPN connections to a single configuration location instead of having to set it up on every potential client.
  20. Thanks, I have it working now. Is there a simple way to constrain the server to only my local network? I'm just playing around with it at this point. Perhaps its fine but I noticed the doctor was aware of the WAN IP in the status page. Edit: Nevermind again. I think I'd have to setup my router to forward ports for this to work so nothing to do.
  21. Hello, I get an error that the java path is missing when I try to start. I tried changing it from 8 (what i starts with) to 16 but it didn't make any difference. This is my only docker. The docker is installed on an unassigned devices disk but not sure if that matters. Attached is a log. Thanks Edit: I see there is a post on the top that probably covers this... log.txt
  22. @jwoolen I appreciate this thread since it seems like its the first info I've seen about the iommu groups on rocketlake. Just to confirm, you do not have ACS override options enabled, is that correct? (In other words, these are the true groups?) If so then Intel has finally fixed the broken ACS separation on the root ports. While rocketlake has a lukewarm response to a lot of people, this and the increased lanes for the DMI and m.2 slots make it much improved platform for passthrough.
  23. I don't know anything about this thread but was pinged because of my gvt-g thread. Its also been awhile since I did that. "All" I had to do to get unraid to use gvt-g was rebuild the kernel used with the gvt-g flags turned on as they were disabled in the default build. The qemu version was fine as is IIRC, although it was compiled without openGL support (not surprising) and openGL is required to allow the gvt-g slices to render to a dma buffer which many people make use of with gvt-g. It still had use even without that feature.
  24. This is a resolved post but I appreciate the data and resolution information. My hardware behaved similarly: On my MSI x470 I noticed that when I used the 3rd slot for VGA passthrough that some of my SATA disks in the array dropped out which sounds like the issue you were having as well. My theory was that the iommu was having some sort of resource conflict or misdirection with devices running off the chipset. Given I had to use the ACS override to force this configuration to work sort of leans on that too, I've always thought people were a bit eager to solve the problem with the ACS override since I've heard it has potential stability concerns. I only recall testing the an older AMD GPU. I believe all tests were with unraid 6.8. Since 3rd slot passthrough was just a test and not required for my use case, I kept using the board and it has worked fine with dual GPUs passed through off the cpu slots. I'm still running the ACS override option to pass through USB cards, it only seemed like the GPU mucked things up.
