cybersteel8 Posted October 29, 2021 Share Posted October 29, 2021 Hello all! This is quite a convenient thread, though I didn't find the answer to my question so I hope I'm not asking the same thing as somebody else. I experienced an unclean shutdown due to a power outage, and when the power returned and the server came back online, it mounted the disks and began a parity check automatically (as expected). I would like to ask - when starting a parity check manually, the "write corrections to parity" is ticked by default. When the parity check starts automatically, is it starting with this ticked or unticked? How do I found out and control this behaviour? Furthermore, I am under the impression that unless I want to correct the parity data, I should untick this option when doing parity checks. This is so that any corrupt data on the data disks can be fixed using the parity data. As this is likely when there is an unexpected power outage, I believe that it would be proper practice to perform the automatic parity check without writing corrections to parity. Is my assessment correct? Thank you all! Quote Link to comment

So there's is nothing I need to change! Thank you! Quote Link to comment

ataman Posted November 16, 2021 Share Posted November 16, 2021 My unraid was off for a few weeks, yesterday I have installed a new HDDs to rebuild (create a new) array and suddenly I started receiving unclean shutdowns. Before it was stable, no issues running for a month or more. Installed HDDs are a brand Ironwolf NAS 4TB, SMART didn't report any issues. Can you please take a look at my logs and advise what could be the reason of my issues? unraid-diagnostics-20211116-1308.zip Quote Link to comment

ataman Posted November 16, 2021 Share Posted November 16, 2021 (edited) Well, difficult to say. My server is running headless thus I don't know exactly what's happening there. But when I'm logging in after such a random 'restart' I see that parity check is in progress. Also in the Fix common problems I see: Your server has detected hardware errors. You should install mcelog via the NerdPack plugin, post your diagnostics and ask for assistance on the unRaid forums. The output of mcelog (if installed) has been logged EDIT: I have connected a GPU to see what's happening with unraid once it's crashed but there's nothing displayed on the screen. Also now the system doesn't reboot itself I need to use power button to turn off and on again. I have configured a syslog however not sure if there's anything interesting here. syslog Edited November 17, 2021 by ataman Quote Link to comment

Can you get that syslog server to put dates on the timestamps? Or just send it to somewhere on Unraid, it will look more like the syslogs we are familiar with. Quote Link to comment
ataman Posted November 17, 2021 Share Posted November 17, 2021 6 hours ago, trurl said: Or just send it to somewhere on Unraid I've managed to save the logs to the flash drive. I brought the server next to my desk and connected to the screen so I can better troubleshoot it. Another restart/unclean shutdown happened around 22:13. What is interested that server didn't reboot, it just stopped responding in the WebGui (or ping, shares etc). On the connected screen I was still able to see the boot up lines with flashing unraid login: After 2 or 3 minutes, I was able to login to the WebGui again, and as always I saw the message about unclean shutdown and parity-check in progress.. Is it possible that it's more a software issue or maybe flash drive which is failing? syslog_flash.txt Quote Link to comment

What is interesting that unraid was working fine for a couple of months and just after installation of new HDDs and applying "New config" the problem started. btw. is it normall to see below lines in the logs? I've noticed them each time when unraid doesn't respond 192.168.1.222 Nov 17 22:14:21 unraid user info emhttpd shcmd (38): /etc/rc.d/rc.samba restart 192.168.1.222 Nov 17 22:14:21 unraid daemon err nmbd[4207] [2021/11/17 22:14:21.962095, 0] ../../source3/nmbd/nmbd.c:59(terminate) 192.168.1.222 Nov 17 22:14:21 unraid daemon err nmbd[4207] Got SIGTERM: going down... 192.168.1.222 Nov 17 22:14:21 unraid daemon err winbindd[4217] [2021/11/17 22:14:21.962147, 0] ../../source3/winbindd/winbindd.c:244(winbindd_sig_term_handler) 192.168.1.222 Nov 17 22:14:21 unraid daemon err winbindd[4217] Got sig[15] terminate (is_parent=1) Quote Link to comment

Since you are running a first gen Ryzen chip, might we assume that you have gone through the BIOS settings to ensure stability with Unraid. Quote Link to comment

That sounds like a bug although not at all clear what could trigger it. Maybe the flash drive had dropped offline so that Unraid could not update the array status on it to say it was successfully stopped? Quote Link to comment

smaster Posted January 20, 2022 Share Posted January 20, 2022 Hey guys, I've been dealing with unclean shutdowns for a while and I'm not sure why. In all honesty, I haven't really had the time to deal with it. However this last time it caused one of my SSDs xfs to become corrupt and it ended up being my plex sdd, so now I'm making time. I have attached a diagnostics file (that is where I saw which SSD is corrupted - sdu), but I have yet to find the root of the problem. To be clear, I've fixed the SSD drive and plex is back up and running, fortunately it wasn't the DB that was corrupted, however I REALLY want to avoid this again. Thank you. Any help is greatly appreciated. tower-diagnostics-20220120-0514.zip Quote Link to comment
trurl Posted January 21, 2022 Share Posted January 21, 2022 When you get a clean shutdown, the array stops first, then Unraid updates the flash drive to indicate the array had stopped, before shutting down. If for some reason that doesn't happen, you get an unclean shutdown. If you do a hard powerdown, or if the shutdown timeout expires before the array stops, then the flash drive doesn't get updated. Or a problem with flash prevents it from being updated, such as readonly or disconnected. Quote Link to comment

Or a problem with flash prevents it from being updated, such as readonly or disconnected. By looking at my diagnostics, is there any way to see what exactly caused the error? I'm almost certain it's not a problem with the flash drive being read only and definitely not disconnected (at least physically). Quote Link to comment
