Hi, we are facing an issue where we can't figure out if its XFS software related, or actually related to hardware, and can't quite figure out why we are facing the issues, though is doesn't seem hardware related.
The issue is with a 102Tb array on a Dell branded LSISAS 3508 (Perc H840).
Running Ubuntu with a 4.15.0-32 (Ubuntu branded), but we have also been running a number of 4.4.0-x with the same issues.
The XFS filsusyem is on a very busy NFS server, and when the issue occurs we see strange issues with NFS, while the system seems healthy on the local server, but at the same time some programs are having problems accessing the fs.
It occure roughly every 14 days, where we have to restart the fs to come back fully working.
Sometimes refusing to unmount cleanly during shutdown, forcing us to fsck the fs on startup.
It looks like its hanging in xlog_grant_head_wait, but I don't know enough to determine what can make it hang there.
Hoping someone in here could have a look and point me in the right direction.
Below is a trace from the last crash we had:

It's a long shot, but can't do much without more information. At first, your
filesystem is waiting for log space, so it could be your log is too small, your
storage is too slow and/or misconfigured, or maybe you you've been hitting a bug
somewhere!?
I don't remember any bug regarding log space issues or reservation problems
happening recently, but I don't use to work on log reservation issues by now,
so, maybe other can have more information if this might be any bug or not.
In the mean time, can you provide more information about the systems where you
are hitting this issue?
Mainle the storage configuration and the xfs_info output of the affected
filesystems.
FWIW:

What happens on your network every 14 days or so? Is there a rogue

Unclean shutdown doesn't require fsck to be run.

Does this repeat every 120s?
These hung task warnings can happen if your workload has overloaded
your raid array and everything doing IO hangs while it catches up.
e.g. you have 6GB of random 4k writes in the controller NV cache and
it takes minutes for it to flush (because random 4k writes are slow)
and make room for new incoming IO....
If the warnings don't repeat, then it means it was a temporary
overload. If the warnings repeat, but change processes and stack
traces then it's a sustained overload condition. If exactly the same
warnings repeat and/or has stalled and doesn't restart, then we've
got some kind of hang occurring and we'll need to look into it
further.
Cheers,
Dave.

Well, we run nightly backups, but thats read ops.
When I look at the load, its not particular more loaded at that time, than normal work.

No, what I sent is the full trace. It happened around 23:23, but no more XFS errors in the log (which is on the ext4 OS disk).
It was working when I came in the following morning aroung 6:45, and worked for some time, but initially failed, and we had to reboot the server to get NFS exports to work.
But, as I said, even though the fs was inaccessible from NFS I could `ls` the filesystem locally, but we really have no indication of it being an NFS problem, as we only see the XFS problem.
It could also boil down to a NFS problem, I just wasn't sure how to read the XFS trace.

Yup, but that can get stuck modifying atime, like the bacula process
in the hung process traces. :)
Hmmm - just a thought - it's hardware raid - it's not running a
background admin op like a media scrub every 14 days, is it?

OK.

Ok, so those processes reported as hung have been woken and made
progress again. It seems like a temporary overload situation.

That could be the same problem, with all the kernel nfsds blocked
waiting for the filesystem so no new NFS requests could be
processed. How many kernel nfsd threads do you run? Local
operations can still be done (don't go through nfsds), and they
won't be slow if they hit the caches rather than have to retreive
data from disk.

Like you, I don't think this is an NFS problem - it smells more of
how huge hardware writeback caches in front of slow disks using
RAID5/6 behave.
i.e. Flushing 100MB of sequential write data from the cache takes a
fraction or a second, flushing 100MB of random 4k write data to
RAID5 luns can take minutes. While the hardware cache and flushing is
supposed to be completely invisible to the OS, we can see it's
impact via unexpectedly high device utilisations and long IO times
for otherwise normal IO loads.
Cheers,
Dave.

Hi there,
I've just a big problem with my XFS file system used on a mdraid raid 5
array.
It started with the situation that the mount of my device was not
possible any more (don't know why, hdd's are OK).
"xfs_repair" results in
"
ERROR: The log head and/or tail cannot be discovered. Attempt to mount
the
filesystem to replay the log or use the -L option to destroy the log
and
attempt a repair.
"
"xfs_repair -L " ran, but unfortunately it was interrupted by an
automatic server shutdown after it stuck after stage 7.
Now, "xfs_repair" results in
"
Phase 1 - Superblock finden und überprüfen...
- Berichts-Prozess in Abständen von 15 Minutes
Phase 2 - ein internes Protokoll benutzen
- Null-Protokoll...
Log inconsistent or not a log (last==0, first!=1)
empty log check failed
zero_log: cannot find log head/tail (xlog_find_tail=22)
ERROR: The log head and/or tail cannot be discovered. Attempt to mount
the
filesystem to replay the log or use the -L option to destroy the log
and

"
A mount attemp results in
"
mount: /mnt/test: Falscher Dateisystemtyp, ungültige Optionen, der
Superblock von /dev/md2 ist beschädigt, fehlende Kodierungsseite oder
ein anderer Fehler.
"
And "xfs_repair -L" results in
"
Phase 1 - Superblock finden und überprüfen...
- Berichts-Prozess in Abständen von 15 Minutes
Phase 2 - ein internes Protokoll benutzen
- Null-Protokoll...
Log inconsistent or not a log (last==0, first!=1)
empty log check failed
zero_log: cannot find log head/tail (xlog_find_tail=22)
"
Sounds linke some kind of "Hen-egg" problem.
Is there any change to get the XFS file sytem back running without
recreating the filesystem?
Kernel:
"
uname -r
4.16.12-1-default
"
Distribution: "Opensuse - Tumbleween"
XFS tools: "xfs_repair Version 4.15.1"
Thank you in advance,
Kind regards,

I just Got it.
The issue seemed to got fixed with 4.16.0-rc1.
Downloading / compiling / using the 4.16.1 version solved my issue.
Sorry for bothering,

Please at least translate the message to english before posting it to the list
Me and several other developers on the list doesn't speak a single word in
German, and going to the .po files to find the translation is too time
consuming.
Cheers.

Also, the translation is cringe-worthy for someone with German as
their mother tongue.

It's been a very long time since the German translations were updated (2009);
I'm sure we'd love to have someone look after them, hint hint? My German
is only good enough to recognize a few words here and there.
Still, it can't be as bad as the e2fsprogs translation referring to
Böcke instead of Blöcke... ;)
In all seriousness, if you would like to update the translations that would
be great. The Polish translation is the only one that receives regular
updates today.

Yes, I've anticipated this hint as soon as having typed the sentence ;).

I've looked into it, but this seems to me like a gargantuan task
because there is so much internal inconsistency that I wouldn't even
know where to start. "Extent" for example: sometimes this is
translated as "Erweiterung" (nonsense, that's extension). Sometimes
it's left verbatim. This is what I'd be leaning towards as well. Other
times, it got translated as "Ausmaß", which in another context is in
fact a translation for "extent" (as in: the extent of a catastrophy),
but makes no sense here. Also "Bereich" and "Umfang" are used
sometimes, of which only the former makes a slight bit of sense. That
in addition to my general under-appreciation of low-level technical
translation. They are usually much less comprehensible and the
gibberish needs to be translated back anyway in order to any sense of,
apart from the fact that the original text is searchable, in stark
contrast to the translation.

Thanks for looking.
Is the German translation bad/embarrassing enough that it should just
be removed? Does it do more harm than good at this point?

Don't distro's have internationalisation teams precisely for doing
translations of packages? If so, shouldn't we be asking for those
teams to do translation work?
Cheers,

Sorta?
https://fedoraproject.org/wiki/L10N/Translate_on_Zanata
https://fedora.zanata.org
We could try to pursue that, but it currently has very few packages
on its "priority" list (anaconda, etc)

I would not want to make that call. Certainly parts of it are
recyclable, so it would be wasteful to throw it all out.
