Ok, thanks. I will try that out!

So, Ram does not seem to be a problem here. The only running containers the last time /mnt/user got dropped and access /mnt/user were Plex, Sonarr, Radarr, Lidarr, Immich. Stopped all other containers from autostarting.

1st pass Passed. Will leave it running through the night.

Going through memtest now, 40% no errors yet

Hey, thanks for reply. not yet. One thing to consider. Can you see any hints regarding corruption? I am a bit concerned about possible data loss, because since the crash I currently cannot reliably access my backups. To reduce the risk, I already started making an inventory of where important data is already backed up, so I can verify that nothing critical is missing and identify gaps before I make bigger changes to the system. At the moment my main concern is not confirmed filesystem corruption, but that the repeated /mnt/user / shfs failures make access unreliable enough that I do not want to assume my backup situation is fully safe until I verify it manually. Already made mistakes, and i want to prevent more mistakes.

Hello, i had a hard server crash some days ago and since then i have many problems with my server. The crash happened while backing up my most important files over night. Backup procedure: SIA renterd providing a S3 bucket backrest backing up a zfs disk to SIA Primarly shfs crashed on the following operations: Creating/Renaming/deleting files inside a zfs dataset over SMB mounting/rescanning my Media Library in plex Maybe you can see any problems regarding corruption or other stuff in the diagnostics. I did not have these problems before the crash, so for me it seems its the most likely cause for this. Maybe i have to recreate my Cache pools? Right now im transferring files from the server to prevent loss of important data. Heres a summary by codex after analyzing the logs: I am seeing repeated /mnt/user failures caused by shfs crashing, not by an obvious disk, XFS, or ZFS I/O error. Primary crash: Apr 12 12:43:38 Unraid shfs: shfs: ../lib/fuse.c:1402: unlink_node: Assertion 'node->nlookup > 1' failed. Immediate context at the time of the crash: Apr 12 12:43:38 Unraid smbd: Could not close dir! fname=binhex-sabnzbdvpn/Neuer Ordner, fd=-1, err=107=Transport endpoint is not connected Immediate follow-up errors: rsyslogd starts failing to write to /mnt/user/syslogs/... with Transport endpoint is not connected Samba starts failing for shares under /mnt/user, for example: canonicalize_connect_path failed for service appdata, path /mnt/user/appdata vfs_ChDir(/mnt/user/appdata) failed: Transport endpoint is not connected emhttpd later reports: malloc_share_locations ... Operation not supported (95): getxattr: /mnt/user/syslogs Later affected shares included: appdata Cryptomator previously also Documents, Walli, and others This does not look like a one-off event. I found the same shfs assertion crash multiple times: Apr 9 19:11:10 Apr 11 23:29:39 Apr 12 00:35:15 Apr 12 12:43:38 A previous crash at Apr 12 00:35:15 also happened during active file access over SMB and produced the same Transport endpoint is not connected fallout. My current conclusion: The primary failure is shfs itself crashing /mnt/user then becomes broken/stale SMB and rsyslog errors are secondary effects In my case, SMB operations on paths under /mnt/user seem to be a likely trigger Additional note: Array disks, cache, and pool mounts themselves appeared healthy in the logs I did not find matching primary XFS/ZFS/media I/O errors around the crash points unraid-diagnostics-20260412-1300.zip

@elibosley Thank you for picking this up!

I just discovered the OIDC login features. Is there a way to completely disable the User/Password login when a OIDC provider is configured? As an extra, just disable it on specific IP-Ranges?

I know its possible to back up the encryption headers of the disks. But in general it is also possible to delete the headers or even initially set up LUKS2 encryption with detached headers. LinuxConfigHow to use LUKS with a detached headerLearn using LUKS with a detached header for better encryption security. This guide covers header backups, detached headers, and full disk encryption. Would it be possible to set up kind of this in Unraid? I think of either having a USB-Stick, or (without modifying any of the mounting scripts of unraid), run a script to fetch and provide the headers somehow. Or maybe write back the headers to the disk before mounting.

Seems like it was either a connection issue, or it was due to the fact my HDD caddies are metal (idk if steel or aluminium) and the Disk PCB made contact with the frame of the caddie. Last Parity Rebuild went through without any errors after reseating the HDD.

There you go unraid-diagnostics-20250101-1614.zip

Seems like a Hardware Problem, but ill ask here first. Since some days my Parity Disk is randomly "Hot Plugging" which results in a remount of the Disk from sde to sdk. This also disables the disk. What can be the Problem here? The disk is mounted in a SAS-Chassis connected to a SAS-Controller.

SOLVED: If you ever get in trouble, because you have special characters in your Passphrase (maybe in combination with a non-english keyboard): Create a new script with: #!/bin/sh export BORG_PASSPHRASE="your_passphrase_with_special_characters" #any borg command works borg mount /path/to/repo /path/to/mountpoint That worked in my case --------------------------------------------------------------------------------------------------- Long story short, i used to back up my most important files with a borgbackup script found here: https://www.reddit.com/r/unRAID/comments/e6l4x6/tutorial_borg_rclone_v2_the_best_method_to/ Due to some circumstances (long story) i wanted to recover parts of my backups, so i tried to recover them on another (Ubuntu 22.04 and Ubuntu on WSL) system with borg mount. However, borg asks me for the repo password, which is not accepted. My password is randomly generated and has some special characters which should be ASCII: $ # ^ These characters can be typed in with the keyboard. I am pretty sure the password is right: Recovered my flash backup and compared password in the script with the backed up one - both the same Compared the repokey with the one i backed up - both the same I know the script worked fine, because i had to manually start backups from time to time, because borgbackup did not get installed automatically through nerdtools. So sometimes i started the script manually and some times tested with borg create. I am thinking of some character encoding issues, that unraid may use a different character encoding or something else, so the password was encoded different when setting up the repository and using the script. Maybe the character ^ makes problems? Because on German keyboards you have to type in ^ with a following keyboard input, otherwise the char does not get printed out on the screen. Can anybody help me out how i could get access to my backups?

Ok, fine. Looking forward to your work on the dynamic port forwarding.

Question about routing other containers related to VPN ports: So i am running the qbittorrenvpn docker which automatically assigns a VPN port to qbittorrent. So i can not use this port anymore for nicotine. The same should apply for PrivoxyVPN. If i already use that port for one application, i can not use it for a second one, right? So in this case, i would need to spin up another VPN container? Or would it be possible to run 2 different VPN connections inside a VPN container?

This problem exists since I have equipped my server with a HBA card and connected all Disks via SAS cables. The specific Disk Model: ST8000VN0022 After first investigations, this model seems to have a bug like mentioned in this thread: 6.9.x, LSI Controllers & Ironwolf Disks Disabling - Summary & Fix So i tried to set up the workarounds by disabling EPC and Low Current Spinup, but this did not fix the Problem. My mover is set up to run at 00:30 daily, the Parity check is set up to run at 00:30 monthly. In the syslogs i could sse that parity check got paused while the mover was running and after resuming, i had read and write errors for that disk which then in turn disabled it. The disk itself is totally fine, the smart readings are also totally fine. I will put this disk in my 3.5" cage today and connect it directly with a SATA cable. But maybe something else is the Problem? unraid-syslog-20240801-1157.zip unraid-diagnostics-20240801-1357.zip

Cables are SAS to Backplane, the server has been restarted several times since then. My PSU is 500W (if i remember correctly) with no graphics card: - i9 9900k - HBA Card - 10gbit Dual SFP+ Card - 9 Disks for the time being. It "should" be fine in terms of Power. Issues started after I put the HBA card in my server, and it is only that one Disk which gets disabled. The disk Smart readings are totally fine. I will put that disk in the 3.5" cage today and directly connect it with a SATA cable and will observe. I will set up an automatic parity check after that and look if it happens again. Because it ONLY happens when starting the parity check. Maybe a crossover issue with the Mover, which starts at the same time like the parity check. Parity check will get paused as long as the mover runs and resume after that. After resuming the parity check i have read errors on my system logs. I will open a support ticket for that. When it happens again after my modifications.

Coming back here, so i disabled both EPC and Low current Spinup. But today when starting the parity check, the drive got disabled again. Will switch the drive now out of the sas controller and connect it directly to the SATA onboard controller. Hope it will fix this issue. Otherwise i will replace the disk sooner or later. Maybe someone has another workaround. Disable spindown for that drive? IDK, because the drives seem to be running all the time and dont spin down.

Fine, will try later as soon as i am home. Thanks.

Hey guys, my second stick seems to be corrupt. I already prepared a new stick for replacement. As i saw on my License Information, i replaced the other one last year in October. However it says Eligible to transfer license (see Picture). So my question: can i just replace the stick and transfer the license without contacting support? That would be VERY GOOD right now, since i will leave for Holidays in 2 Days.

In case anybody has problems finding the right tools. Theres an open source alternative "openSeaChest" on gihub which seems to work too. It has releases for different types of platforms: https://github.com/Seagate/openSeaChest

Hi, so at the end it seems the problem was running Duplicati with external Backup in parallel to any other Copying/Backup inside of the array. It was causing long CPU and RAM spikes which made my system unresponsive. Docker Apps and VMs were still reachable and responsive, but Unraid itself was not. I changed to Borg Backup now for the external Backups, did not have any error or hiccup anymore since then. CPU and RAM spikes went away. Still have to do the MEMTEST, did not do that yet.

My new cache disk is always at "high" reading bandwidth. Is that normal (for a ZFS drive)? My other ZFS drives dont do that. This one is hosting my appdata and domains folders

Yea i can understand this. There is some trust you have to put into this from both sides to either not try to decrypt the backups or to not store any criminal stuff on the other side. You have no control over the data other than encrypting it. But i really like the idea of solutions like SIA, store your data decentralized all over the world in a Raid-Like protected storage. The problem is, there is no solution yet to natively bind your storage as a volume or disk. Like mounting via rclone or fuse.

Just had this idea, could not find this anywhere. Some of you maybe know SIA, a decentralized cloud based storage, where everybody can rent and provide decentralized storage. I like this idea. Maybe there are other people around, which want to back up some stuff, but dont want to rely on one provider. I back up my stuff externally on a Storage Box at Hetzner. But its like a "single point of failure". Sure i have backups locally too, but i would be more calmed, if i knew, there is some backup somewhere else. For example my Bitwarden-Safe and very important documents. I already spread them a bit (locally, encrypted USB drives, external backup), but what if everything close would get lost? So maybe there are ppl who like to share some GB of their storage to each other?
