Rebuild on a bigger drive, 80 errors, network stack crashed, GUI not reachable, diagnostics fail

[Fireball3]

Hey guys,

I was running out of space and decided to upgrade one 1.5TB drive that was not so healthy either.

During the rebuild it found 80 errors, I was able to see the GUI by that time.

 

2 hours before estimated finish of the rebuild, I fired up a movie but the one I chose was failing after 2 or so minutes.

Tried another one and my Popcorn (media player) ended up in an unstable condition.

Rebooted the media player and tried again, same thing.

Well, I thought I check the issue on my PC.

Browser said something about connection refused.

Checked the shares and I noticed it was laggy when opening the directories. A few seconds later the server did not respond any more.

 

Well, I thought by myself to let the rebuild finish.

Sleep will powerdown the rig after finishing and tomorrow everything will be OK.

 

This morning I checked the server status and found it up and running.

Still not accessible via GUI nor shares nor telnet.

 

Plugged a keyboard and a screen to grab the diagnostics.

Fist issue, see attached pic. What should I do now?

The server is still running and waiting for yor input.

Try to at least get the syslog.

This sounds like memory corruption. I would run a memory test.

 

[Fireball3]

OK, got the syslog already but need to shutdown/reboot to pull it off the stick.

Anything else I should get before rebooting?

Will do a memtest afterwards.

[JorgeB]

Reboot and run memtest, rest of the diagnostics can be downloaded after.

[Fireball3]

OK, indeed a memory issue. Right after start of memtest everything came up red.

 

Server is up again with some other RAM and the movies play just fine.

Rebuild was successful.

Will run a check against my backup server to see what those 80 errors during rebuild were about.

The GUI says now:

Last check completed on Sat 23 Sep 2017 12:04:28 AM CEST (today), finding 0 errors.

Thanks for your quick help guys!
