Thank you.. That helped.. I fixed my Flash. Then i also tried to update code to stable version and was getting MD5 error. Suspected Ram issue. Ran MEMTEST and Ram failed it. I took out the sticks and tried to test each one separately and they both passed on their own :). I put back both and tested again and MEMTEST passed. Strange. Maybe Ram is about to fail soon or maybe was not very well seated in the slots. After starting OS , i am able to update to highest stable level and VMs started as well after a little repair of the bad shutdown. Thank you again for directing me in the right direction.

I shut down docker and restarted the array. Now I can see my shares. I am guessing an auto update happen on docker and maybe it screwed up my array. my VMs having issues now as well. They keep crashing and going into recovery . Array parity started I figured i let it run to make sure all my drives are ok. Then i will enable docker one at a time to see which one is crashing the array. Also probably need to rebuild my VMs? tower-diagnostics-20231017-2159.zip

Hello, I am not an expert. Not sure what happen. Array was running for a long time without any issues. Today in AM, noticed that I cant connect to a VM. Check array and it was shut down with error for a missing drive. I rebooted and it found the disk and came up fine after that. But now I see that shares are not showing. Not sure where to start. If this happen before, maybe someone can direct me to another thread for this issue. I saw a few about permissions issues on mnt/user but I did not touch anything. Thank you tower-diagnostics-20231017-2025.zip

Thank you.. Is there a recommended combo for CPU/Mobo for good performance like running multiple VMs, Dockers (Plex) etc..? Thanks

I upgrade to ASUS PRIME X670-P with AMD RYZEN 9 7900X a little while back. My Unraid started crashing every 15-30 min. I upgraded BIOS and UnRaid to 6.12.0 rc1 based on recommendation in attached thread and it seems to stabilize. Today it crashed again. First time from March 24th. Unlike before, now i was capturing logs on flash so attaching with diagnostic. I just upgraded to 6.12.0 rc2 (latest possible) as well Was hoping the experts here maybe can spot something in the logs that I can do to make my Unraid stable. Crash happened 4/1/23 I think around 18:xx or so. Thank you in advance. syslog 4.1.2023 tower-diagnostics-20230401-2146.zip

Its been stable since my last post. till running 6.12rc1 and the only thing i did was change IP to static. dont know if that helped somehow but only change i did after i upgraded BIOS and unraid to 6.12rc1

Spoke too soon. Crashed again. Run for a 5-7 hours. It completely goes dead. Even keyboard and monitor connected directly to the server have no response or even display. And it somehow kills my home network. Not sure what it is doing with the ethernet but a bunch of devices on my flat home network go down every time server crashes and cant even connect on their ethernet ports (few ethernet connected PCs, Wifi Mesh router, etc) . As soon as I unplug the UnRaid ethernet port, all devices instantly reconnect. Not IP confict. Some sort of LAN broadcast storm or something. I figured out how to save logs to flash. Will see if I capture anything that way

Thank you for the feedback. I had the latest ver of BIOS running and upgraded to Unraid to 6.12 and so far the server running the longest without crash. I hope that was it.. if i make it for a few days, it would mean problem solved. On a side note. what is C-States as I could not find that in my BIOS settings. Power efficiency feature?

Hi. hopefully someone can help me out with what i can do to recover. I had an Unraid running 6.10.3 and wanted a faster CPU. I initially updated the software to latest 6.11.5. Then I swapped my mobo and cpu to the new hardware (ASUS PRIME X670-P with AMD RYZEN 9 7900X) and started the array. Everything came up fine and i used it for a day but during normal use, my shares disappeared a few times, some strange container issues. Some posts suggested an it worked to reboot to fix that. I figured I have an issue with 6.11.5 and reverted to 6.10.3. The situation now my array runs and then just crashes. Can not connect, console as you see in the attached pic shows kernel crash it seems. the strangest thing is when it crashes it takes out my home network until i pull out ethernet cable which restores connectivity. I dont think that is critical but wanted to mention. Attached are some files i can capture while array stays up. Also started to get USB error for USB stick with config. I think USB is fine, it was fine for a few days with this array and it starts fine but then I guess gives this error. USB flash drive failure: 17-03-2023 03:17 Alert [TOWER] - USB drive is not read-write Cruzer_Fit (sda) When its down i cant connect and nothing responds. Snapped a pic of the screen. I am not an expert on UnRaid or linux but it was a very stable system for a long time. Maybe an issue with the Mobo or CPU? Any thoughts are greatly appreciated tower-diagnostics-20230316-2214.zip tower-syslog-20230317-0215.zip

Hello I noticed an I/O error for UnRAID boot USB flash card Feb 12 16:29:37 Tower kernel: print_req_error: I/O error, dev sda, sector 15653872 does this mean flash card is failing? tower-diagnostics-20190213-0527.zip

Thank you. I was just focusing on errors for preclear not the array so did not think diag files would be needed to understand if errors is critical. Anyway, preclear just errored out with a message : Preclear: 30-01-2019 21:38 FAIL! Pre-read verification failed. Drive is brand new and i changed the cable. I can RMA it but my only concern that out of total of 6 Drives (5 plus Parity) , 2 started having errors at about the same time and if that is maybe an indication of MoBo issue? tower-diagnostics-20190130-2145.zip

I stopped the preclear and swapped SATA cable with brand new cable and started preclear again.. Still getting these errors. blk_update_request: I/O error, dev sdb tower-syslog-20190130-2108.zip

So I I stopped my array removed disk 4 (dont really need any data on it), Added new Drive (sdb) that i will use as parity drive with new config started preclear and right of the start i see the following in the logs and SMART 197? Does these error means drive is bad? tower-syslog-20190130-2033.zip

So I stop the array, remove disk 4, add new drive build new configuration with remaining disks 1,2,3,5 keep old Parity Disk as unassigned assign new disk after preclear as new Parity Disk start array to rebuild party on new disk. Question: the data and folders and shares i have now on old config and on disk 1,2,3,5 will actually be seen in new config array??

Well copied the data to disk 5 as soon as i saw errors on disk 4. Thought was if disk 4 fails i would still have the data and I can always rebuild parity disk. And i was not sure about rebuilding just disk 4 as Parity disk also started to have read errors. I have a feel that if I just replace disk 4 with new drive and try to rebuild it, with parity disk having read errors, that would fail. If that happens, what would i do?

Thank you guys. That is the reason for my question as both my single parity and one disk showing errors and i was not clear which order to use to recover both disks. I actually dont care for disk 4 data as I moved it to disk 5 via Krusader ( it was empty) . So I am willing to simply remove disk 4 out of the array and replace Parity Disk with new drive and rebuild parity. I was just not sure how data i moved to disk 5 will show up as part of array. will UNRAID find that data/folders on disk 5? Also, Alternatively, i already moved data to disk 5 so i can replace disk 4 with a new drive and copy data back from disk 5 to disk 4 manually without rebuilding array and relying on parity drive? will that work? "Are these parity sync errors reported at the end of parity check? Or are you talking about numbers in the Errors column on Main?" Yes i see errors on Main screen after i run by weekly Parity Check "Was it an Extended test you ran?" Yes i run extended but both showing completed without errors. a bit confusing as in logs i see read errors.

Thats right.. forgot.. added.... tower-diagnostics-20190128-1637.zip

)I posted for support help a while back for one drive (drive 4) and the solution was to swap cables. That seemed to help but now i am getting errors on same drive and now on parity drive after i run parity check. I swapped cables to both drives but it did not seem to help. I run SMARTs test but it seem to complete without errors (Last SMART test result: Completed without error) Regardless, i wanted to swap the drives but wanted to know the right order of swapping drive (Drive 4 in my case) and Parity drive so that I will not loose any data. I already copied my data from Drive 4 to Drive 5 just in case.

There were some read errors I think I saw in sept.. so what do you think this could be? Cable? i get this errors once a week or so but drive seems ok and SMART has no other errors when i run long checks.

Hello, Hopefully, someone can answer this question. I started getting this error for disk4. I run SMART both short and long tests without errors. Is my disk 4 really failing? I do see some errors in logs. Event: unRAID Disk 4 SMART message [198] Subject: Notice [TOWER] - offline uncorrectable returned to normal value Description: WDC_WD20EARS-00MVWB0_WD-WCAZA0729060 (sdb) Importance: normal tower-smart-20181011-1720.zip tower-syslog-20181011-1717.zip

Yes .. I/O error.. ok.. you might be right.. going thru this whole effort and then VM crashing all the time because it is missing some files might not be worth it. Thank you for your support.

I recovered all by 1x30Gb file (VM vdisk). Should i try running reiserfsck on failed disk? any other options within unRAID to get low level access to the disk? I am willing to try anything drastic. VM was not important but a pain to reinstall OS.

Was thinking to upgrade but could not find time.. good to know.. thank you

I totally say it is my fault as I was not reading descriptions as i was going thru rebuild and it is my first failure/rebuild (plus i am not an expert on UnRAID), but to jonathan's point, i do think Formatting a drive would not make sense to have anywhere near array operations. I think it belongs to disk operations section or something like a utility like "preclear"

Trurl.. things are never easy so as i am copying the files, one vdisk for one of the VMs i had does not read on old drive (30G file). You mentioned there is a way to get data after format. If I want to just get one file, how complicated is that process?
