Random lockups

Hi all,

 

I've been having an issue over the last several days and I'm struggling to find a cause for it. That issue being my server seemingly locking up. I can no longer access it on my network, router loses arp etc.. But the fans are still spinning (hence my belief that it's a lockup).

 

When it started, I was running 6.1.9, Today I figured I'd upgrade to latest (6.2.4) to try and fix the issue, but no such luck.

 

I tried turning redoing my entire docker image, in the hope that this may fix the issue, but it's still happening.

 

Even with the docker image turned off, I was transferring ~11GB of small files, and it froze while doing so.

 

I telnetted in and ran 'tail -f /var/log/syslog' and let it run, fortunately? the next crash happened about 5 minutes later. Reading the log, I have a feeling that it may be saying there's a CPU issue, but I'm not exactly an expert on reading syslogs ...

 

If anyone can assist, that'd be brilliant!

 

Cheers

 

Kharn

 

I'll post the syslog over several posts, as it's hitting the character limit;

Some of that makes me think you need to check filesystem on disk7. But if it won't stay up long enough you can't.

 

Have you done a memtest recently?

Edit on the flash drive config/disk.cfg and change startArray="yes" to be startArray="no" and reboot

 

Then run filesystem checks on disk7  (all assuming of course that memtest passes fine  as per trurl's advice)

  • Author

Awesome, but just wish to clarify before I do anything;

 

Memtest: Grab memtest ISO, plug monitor & keyboard in, run test for 24 hours? or is there a magical easy unraid way to do it?

Filesystem: fsck?

 

I'll wait until I hear back so I don't break anything .. I have it on with the array unmounted, as per your instructions, see if it runs for a while (19ish minutes so far) ..

 

 

 

  • Community Expert

There is a memtest on the boot menu when before unRAID starts.

  • Author

sweet, I'll rip out the old monitor then :) thanks!

 

oh, and what of the file check?!

  • Author

Brilliant, thank you, I'll report once it's all done...

Hey guys,

Any XFS gurus here?

 

I tried running the repair tool, and got an error. System is running in maintenance mode.

 

Phase 1 - find and verify superblock...
        - block cache size set to 639272 entries
Phase 2 - using internal log
        - zero log...
zero_log: head block 1724587 tail block 1719557
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair.  If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.

 

and running "mount" had a whinge;

 

mount: wrong fs type, bad option, bad superblock on /dev/sdb,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

 

and dmesg

 

[16197.347989] UDF-fs: warning (device sdb): udf_fill_super: No partition found (2)

 

I know this is heaps of info, but I don't wanna be that guy who has to be asked 100 questions because I've missed something :)

 

Cheers

Reading a bunch of other posts .. "-L" is my option ... worst case, I have parity ..

Reading a bunch of other posts .. "-L" is my option ... worst case, I have parity ..

Parity does not keep individual files, it's only able to recreate the whole drive as is, filesystem errors and all.

 

Your random lockups may have caused the filesystem corruption, not the other way around, so after you get the corruption repaired, I'd still run the fix common problems plugin using troubleshooting mode for a couple days to see if the root cause is gone.

  • Author

Hey Johathanm, do I "run the system as normal" while running that plugin, or should I leave it in maintenance mode?

 

if I'm to run as normal, should I do a parity check?

 

 

  • Author

xfs_repair fixed all issues (using -L) ... when I do a normal check -nv it is clean now .. Good news there ..

 

 

Hey Johathanm, do I "run the system as normal" while running that plugin, or should I leave it in maintenance mode?

After the file system checks come back ok, you should be able to run normally. A non-correcting parity check wouldn't be a bad idea, it will stress the system and if it fails, the fcp troubleshooting mode will capture the syslog live right until the system falls over.

 

You shouldn't run troubleshooting mode continuously for more than a day or so at a time.

  • Author

Brilliant, I've fired it up normal, and I'm running a parity check with no write .. I've put FCP in to troubleshooting mode .. so .. now we wait :D

 

Hopefully it lasts ..

 

Will update if it borks again, or after a couple of days ..

If the parity check shows any errors, post diagnostics and wait for advice. Theoretically it should come back with exactly zero errors.

If / when you're satisfied the system is running good, you'll have to reboot it to cancel FCP's troubleshooting mode.  (Leaving that running for months on end will cause issues due to the excessive logging it performs to try and locate problems / trends)
  • Author

Parity check is complete, no errors..

 

Nothing on FCP so far .. (other than some warnings about shared folders split between cache and drives)..

 

Cheers for the heads up with the reboot, squid; I'll do that in a few days (all going well) ..

  • Author

Just wanted to say a big thank you to everyone who assisted me on this ..

 

No errors from FCS

No lockups

With no actually metric .. It "feels" like it's running faster..

 

I didn't actually to the memtest, just the FS check .. But that solved it ..

 

:-* :-* :-*  ;D
