[Brendan Tildesley]

I'm getting this error running guix pull.

build of 
/gnu/store/yfy990mq3ikmkhawgc35z2f2ryqdxn09-guix-system-tests.drv failed


it appears to be caused by the latest commit. using --commit to switch 
to the previous commit work.

I've CC'd the author and commiter.

make check-system TESTS="loadable-kernel-modules-0 loadable-kernel-modules-1 loadable-kernel-modules-2" does work fine.

So I'm guessing it's another system test.  I'm running them all now.

Uhhh--we haven't changed anything there.

Ok I may have jumped the gun a little. the first error I had looked like 
it was related to it but my battery died before i could post it, so i 
reran it and got another error, which didnt seem so related. It was odd 
that 8c88e2422 succeeded but later commits failed twice, and another irc 
user found their guix pull failing at the same time.
However, I had these errors in dmesg so I ran guix gc followed by guix 
pull and it worked. it may be because my ext4 is hitting limits and guix 
isnt coping with that well.

Closing since it seems to unrelated. Sorry for wasting your time. I 
think it may have been my ext4 having too many files. i deleted all my 
system generations and gc'd a lot of stuff, and it seems to be miss 
behaving. perhaps it is a different kind of guix bug that it doesnt cope 
with this issue:

Worse: it's an ext4 bug (well, behaviour).

This happens when a directory, almost certainly /gnu/store/.links, 
contains more entries than can fit in ext4's ‘dir_index’ hash 
table.  The file system simply punts.

You can disable this optimisation with tune2fs -O ^dir_index …. 
You'll lose some theoretical performance but I haven't heard 
complaints in practice.  You're not the first one to encounter 
this problem.

If that's unacceptable, you can reconfigure your guix-daemon with 
‘--disable-deduplication’ in exchange for more storage space for 
newer generations.

Or switch to btrfs for a newer, shinier set of pathological 
gotchas but not this one :-)

One could work around this in Guix if one were motivated:
- Ignore file system failure instead of making it fatal, falling 
  back to ‘--disable-deduplication’ behaviour, which is probably 
  the right thing to do; or
- store .links in ./n/e/sted directories, which will degrade 
  performance on file systems that handle collisions properly and 
  is probably not worth the headache.

Kind regards,

T G-R

No, if in doubt, please always report.

Is there already a bug report for that problem?  I think the least we
could do is check on startup if that ext4 option is set or not--or
better yet, automatically degrade deduplication to duplication when it
doesn't work otherwise.

AFAICS this problem is now fixed (I just pulled to
0e8564f8f0f51535b9fd7893082d12eef769a7fc).  Closing!
