During troubleshooting the unraid-server wasn't connected to the network. After connecting the server to the network, I was totally stunned 8-))))))))) that the GUI is accessible and also usable. Everything looks fine and after replacing the license key, everything is up and running again. I can open a working terminal via SSH. On the local screen I still see this weird screen as shown above and no local terminal. I'm not really sure that everything is fine, but for now, I'm pretty happy!!!

I attached the most important parts of the /config folder (removed plugin folders & Key File). Can anyone see something "corrupt"? I don't have another backup of the config 8-(( How difficult is the "recreation" of the config from scratch? Thanks a lot. Frank config_copy.zip

I extracted the /config folder from the current USB-Flash drive, created a new flash drive (64GB) and copied the /config to new usb stick. I ended up with a strange kind of error (see the attached picture). I booted with a different UnRaid stick and the server booted correctly. So, it seems that I haven't an hardware issue but an issue with the usb stick and the config data itself. Any idea what to do next? Thanks

Hi Everyone, today I experianced a fundamental server crash. After reboot I don't reach the point where I can connect to the server via network. Attached you find a screenshot from the local attached screen. Can you help? What is potentially damaged? Thanks a lot!!! Frank

Sorry I have problems to upload the diagnostic file (error: -200)

Hi All, this night my zfs-Pool crashed. I had to reboot the server and now the pool can't be mounted (Unmountable: Unsupported or no file system. I attach the diags. May be someone can help. If I try to import the pool from the command line, I get the following result: root@UnRaid-Server:/# zpool import cache_docker_vm cannot import 'cache_docker_vm': I/O error Destroy and re-create the pool from a backup source. I get same result, if I try to import read only: root@UnRaid-Server:~# zpool import -o readonly=on cache_docker_vm cannot import 'cache_docker_vm': I/O error Destroy and re-create the pool from a backup source. What can I do, to at least safe the data? Thanks in advance. Frank unraid-server-diagnostics-20231008-0802.zip

Sorry Guys, during the "New Config" procedure a lot of other settings were changed to default values. So did the setting to pause the parity run on some temperature levels. I set the value for "Pause and resume array operations if disks overheat" to no and it seems to work now.

I made a mem-test with works out fine. I changed to two new SSDs. Until now, no further problems. I confess, I downgraded from 6.11.0 to 6.10.3.

Hi All, I shrinked my array (removed 3 disks) using the "New Configuration" method. In principle all works fine, but the current parity run pauses every few minutes with the error messages, that a few drives are overheated, which they are not (my first alert temperature is 45°C). But anyway I can't remember that a parity run ever stops because of an overheated disk. Any idea? Thanks a lot. Greetings Frank unraid-server-diagnostics-20221008-1016.zip

No, I didn't perform any memtests.

Hi All, It seems that I have a problem with one of my SSDs. What should be the next steps? Thanks. Frank. unraid-server-diagnostics-20220926-1850.zip

Hi All, currently I'm copying all data from one drive (disk 8 ) to another empty drive (disk 9 ) using unBALANCE. The copy process itself works absolutely fine. What I dont't understand is the fact das all other drives have read activity at the same time. I tried it many times and the read transactions are directely corellated to the use of unBALANCE. I would have expected that I see activity on disk 8, disk 9 and the parity drive only. Do anybody know why that is happend? During a long copy process this behaviour is not desired because all the spinned up drives need a lot of electric power. Thanks in advance. Best Regards, Frank

Hi All, sorry I'm back. Something is still wrong. Everytime I try to copy all the data from my docker ssd I get error messages and the copy process stops. I changed the controller for the SSDs (now all on the internal intel controller). But still I get these strange error messages (11:30am). Why I want to copy all data from the Docker SSD? Because I have two single SSDs, one for all Dockers and one for all VMs. I want to create a Cache Pools instead (for redundency reasons) an run dockers an VMs from this Pool. Any Idea? Thanks! Best regards Frank unraid-server-diagnostics-20220213-1145.zip

Hi, the rebuild on an other spare disc is now running. So far erverthing works fine. During the drive swap, I checked all cable connections, maybe there was a small error there. Additionally - to be on the safe side - I ordered one of the recommanded LSI SAS Contoller. However, I doubt that the old controller type has a fundamental problem, because it has been working absolutely flawlessly for years, with hard drives and SSDs. But anyway, if I can further reduce the risk of failure of my "beloved" UnRaid server with a controller change, then I'm happy to do so. 😉 Best Regards Frank

Sorry, ignore the question how to revive disc 9, I found the procedure. But is it wise to start a rebuild as long I'm not sure, that erverything with the conroller is o.k?

I have 4 SSDs in my setup. I switched all of them to the onboard intel SATA Controller. Everything looks fine for the moment.

Hi All, it's getting worse. My attempt to copy some data from my cache_VM drive to a data-disc using the mover ended in a lot of write errors on the data-disc which is now disabled. Is it possible that my 8port SATA extension card is somehow damaged? As a precaution, I stopped the array. Im afraid that I could really loose data now.

Hi All, I have a single Cache SSD drive in my UnRaid setting where all my Docker Applications are running. In the last couple of month ramdomly sector relacations on this drive took place. Last night I tried to transfer all data to a "classical" data disc to save the data.

Hi All, I have a problem when I try to access my personel banking data (on an Unraid-Share) with my banking application running on a windows VM. I get the following error message (see picture below). Sorry it's in German, it means that the file don't have a valid Win32-FileTime (parameter name: filetime). If I copy the file from the Unraid share to the VM-Filesystem an back, then I can access the file without any problems. If I save the file again on the Unraid share, the problem is back. The only thing that I changed in the last weeks, is to activate the SMB Settings paramenter "Enhanced macOS interoperability". Any ideas? Thank You! Frank. PS: I checked system time on Unraid and the VM. There are identical.

Hi All, I could fix it by using a backup libvrt.img file. I tried to move all the VM "stuff" to a new VM Cache Pool and somehow damage something. 😒 For now the VMs are running again - which is fine - but the plan stands, that I want to move everything related to VMs to this seperate Cache pool. Is there a procedure how I can safely do this? Thanks.

Hi, I have a problem to start the VM Manager, the pathes are all correct, but there seems to be a problem with the libvrt.img file. Can anybody help? I attached the diagnostics files. Thanks a lot!!! unraid-server-diagnostics-20210429-2252.zip

Hi, I have a Windows 10 virtual machine which doesn't work properly anymore. What happend? Somehow I deleted the Virto Driver ISO and the OS install ISO. After this event I downloaded the driver (same Version) and created a new ISO install image for Windows 10. After that I could start the VM again, but the VM stops working after some hours or several minutes.

Hi, today I configured the second nic to be backup (bonding) of the first NIC. The configuration works fine, but now I can't access my VMs anymore. Do I have to change something? The virbr0 device seems to have a problem (see log). But why? Can you help? Thanks! Edit: Sorry, I found the error. In the VM configuration the nic was set from br0 to vibr0. I had to change them back to br0 and now everything is running just fine. Thanks! Greetings Frank unraid-server-diagnostics-20171031-1100.zip
