All fine now, thank you for the help. I'll have to read up more on this and it's the first time using this command. Appreciate the learning experience. Thanks!

disk check done again without the -n, see bwlo:

The file check on disk 15 was this output: Not sure what the above means. The drive is powered up and the cage it's in is powered on. syslogs are attached. syslog syslog-previous

Hi JorgeB, Happy Holidays and new year is just around the corner, appreciate the help so far. I've attached the new diagnostics data. The machine was restarted a few times and managed to get a rebuild going but then the server becomes unresponsive after a few hours. Now the array is seeing lots of errors on the disks. Not sure what the cause is, help will be appreciated. htpc-vault-diagnostics-20231227-1534.zip

1 of 2 parity disks is disabled as is one of the data array disks. happened all of a sudden, not sure why. last action was to rebuild a bad disk just a few days prior. htpc-vault-diagnostics-20231223-1713.zip

array seems to be fine now, what a relief. Also, I have added a ssd to the pool (I think this will be automatically placed in RAID 1) but it says the device is disabled. What is the proper way to troubleshoot? Any help here is again appreciated.

I'm rebuilding parity now. HBA went from 70mb/s to 110mb/s just with new grease. Thanks for the help, will update more later.

That's correct, Parity was never achieved as the server reboots. I'll follow your suggestion and provide an update later.

Short update. Reboot in safe mode and then try to start the array, it performs a read check. All drives connected to HBA are reading errors in the millions. Drives attached to mobo are fine. Removed HBA (LSI 3100 I think - 16 port) and changed the thermal grease on the chips. They were all completely dry. Reinserted and now performing another read check - no errors this time but parity drives are now disabled. One is Toshiba and the other Seagate Ironwolf, both new. Tried to get syslog from last reboot but the syslog was 4gb is size, tried to d/l but system rebooted again and came with a blank syslog. Changing the settings to have syslog rotation so it should keep more than one now.

Hi, Server has been working for around 2 months without issue. Removed a disk and am now shrinking the array. Upon rebuild the server reboots at random intervals. Sometimes I get to 7%, 15%, 22", 45%, 70% and then I find the machine has rebooted. I have thought it to be a cooling issue and have server panels removed, included a floor fan, and opened windows. Ambient temp is 22C and the hottest drive is 40C during rebuild. it could be a hardware issue but everything is less than 3 months old. PSU is 850W Corsair, Intel i3, 16gb ram, all branded. The LSI HBA card might be over heating too, but hard to say but I've given as much ventilation as possible. I have one bad disk in cache pool but I don't think that could cause a reboot. htpc-vault-diagnostics-20230918-1357.zip
