April 6, 20251 yr Unraid randomly hard resets after faulty drive was replaced and then freeze at post and replaced flash drive replaced both but something is wrong still cant figure out any clues to what is causing it tower2-diagnostics-20250405-1650.zip
April 6, 20251 yr Community Expert 8 hours ago, hoflande said: Unraid randomly hard resets Do you mean the server reboots by itself? If yes, that's almost always a hardware issue.
April 6, 20251 yr Author what hardware would cause it run fine for days and then just crash randomly and freeze at post just not sure what would cause that. never diagnosed something like that. usually its predictable in my experience its immediate or related to high usage or something. there is no predictability it will run for a week or two with no issues i think there is corruption or something or vm related.
April 6, 20251 yr Community Expert Could be multiple things, does it just crash or actually reboot by itself?
April 10, 20251 yr Community Expert Unfortunately, there's nothing relevant logged, and if the server reboots by itself it's almost always hardware like mentioned, since you have multiple RAM sticks, try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.
April 14, 20251 yr Author have you guys ever seen a 9305-24i IT Mode 24-Port SAS 12Gb/s PCI-E 3.0 Controller Card cause computer to do this because i think that was the issue
April 17, 20251 yr Author ok happend agian my motherboard supports ecc memory and i have udimm ecc memory installed just wanted to see if there is a way to test memory that way or is it just a guessing game it seems to be right around 3 day mark of running fine then boom it reboots to freeze at post.

April 21, 20251 yr Author Ok I've narrowed it down a little it's constantly around 3 Days disabled zfs cache pool changed it to btrfs but didn't format it and now it didn't hang at post when it reset so I formated cache drive going to see if it is software related with that partition. in my experience hardware isn't this predictable trying not to spend 150$ per stick of memory without 100 percent knowing its memory tried each memory stick same issue gonna check if there is a second syslog that might help Edited April 21, 20251 yr by hoflande
April 21, 20251 yr Community Expert There's nothing on that syslog other than syslog server related messages. 7 hours ago, hoflande said: trying not to spend 150$ per stick of memory That's why I recommended testing with one stick at a time, no need to spend money for that.
May 4, 20251 yr Author tested one stick at a time all cause it to crash bought new memory still crashes then unraid is telling me my flash drive is corrupted. orderd new power supply still crashes. so now i ordered new motherboard hoping that is it if not its a bad cpu is my guess its weird with new memory it lasts a little longer before it crashes you know if am5 cpus have isues like this not sure if thats whats next to try tower-diagnostics-20250503-2142.zip
May 4, 20251 yr Author got syslogs from usb and they are bigger hopefully there is some clue syslog syslog-previous
May 4, 20251 yr Community Expert Still nothing logged, see if this helps: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/page/2/#findComment-819173
May 7, 20251 yr Author So I have narrowed it down to being vm related if I don't start vm it runs for days if I start vm it crashes within 24 hours not sure what to do I tried what you posted it did seem a little better maybe like 2 hours longer but still related to vm anything in my diagnostics to show vm related issues
May 7, 20251 yr Community Expert Post diagnostics with the array started in normal (not maintenance) mode.
May 7, 20251 yr Community Expert Unlikely to be the cause of crashes, but your "default shares" have files on the array. https://docs.unraid.net/unraid-os/manual/shares/user-shares/#default-shares appdata shareUseCache="prefer" # Share exists on cache, disk1, disk2, disk9, disk15, disk17, disk22 domains shareUseCache="only" # Share exists on cache, disk6 isos shareUseCache="only" # Share exists on cache, disk1, disk2, disk3, disk4, disk15, disk16, disk19, disk20, disk21, disk22 system shareUseCache="prefer" # Share exists on cache, disk1, disk2 Better if these have all files on cache or other pool, with nothing on the array, so Docker/VM performance isn't impacted by slower array reads and especially writes, and so array disks can spin down since these files are always open. You have a lot of disks. Are you sure there isn't some power problem?
May 7, 20251 yr Author Yes I checked power supply with a cheap tester from Amazon and it says a PG 510ms is the only issue I also bought a new Asus power supply 800watt still crashed so I don't think that is the issue also it's in a super micro 4u server so it has two power supplies. I will try that thanks.
May 11, 20251 yr Author So I've replaced memory CPU motherboard power supply not hardware I had to switch CPU settings in vm to emulated no more hard resets
