Although I don't have these error messages, I'm having fuse crashes as frequent as you. I have disabled write-behind and the mount has been running over the weekend with heavy usage and no issues.

I can provide coredumps before disabling write-behind if needed. I opened a BZ report with the crashes that I was having.

Alright. I've enabled core-dumping (hopefully), so now I'm waiting for the next crash to see if it dumps a core for you guys to remotely debug.

Then I can consider setting performance.write-behind to off and monitoring for further crashes.

Sincerely,
Artem

Hi Nithya,

I can try to disable write-behind as long as it doesn't heavily impact performance for us. Which option is it exactly? I don't see it set in my list of changed volume variables that I sent you guys earlier.

The option is performance.write-behind


Sincerely,
Artem

Hi Artem,

We have found the cause of one crash. Unfortunately we have not managed to reproduce the one you reported so we don't know if it is the same cause.

Can you disable write-behind on the volume and let us know if it solves the problem? If yes, it is likely to be the same issue.


regards,
Nithya

Sorry to disappoint, but the crash just happened again, so lru-limit=0 didn't help.

Let's see if it stops crashing or not.

Hi Artem,

Do you still see the crashes with 5.3? If yes, please try mount the volume using the mount option lru-limit=0 and see if that helps. We are looking into the crashes and will update when have a fix.

Also, please provide the gluster volume info for the volume in question.

The fuse crash happened two more times, but this time monit helped recover within 1 minute, so it's a great workaround for now.

What's odd is that the crashes are only happening on one of 4 servers, and I don't know why.

The fuse crash happened again yesterday, to another volume. Are there any mount options that could help mitigate this?

In the meantime, I set up a monit (https://mmonit.com/monit/) task to watch and restart the mount, which works and recovers the mount point within a minute. Not ideal, but a temporary workaround.

By the way, the way to reproduce this "Transport endpoint is not connected" condition for testing purposes is to kill -9 the right "glusterfs --process-name fuse" process.


monit check:
check filesystem glusterfs_data1 with path /mnt/glusterfs_data1
  start program  = "/bin/mount  /mnt/glusterfs_data1"
  stop program  = "/bin/umount /mnt/glusterfs_data1"
  if space usage > 90% for 5 times within 15 cycles
    then alert else if succeeded for 10 cycles then alert

Hi,

The first (and so far only) crash happened at 2am the next day after we upgraded, on only one of four servers and only to one of two mounts.

I have no idea what caused it, but yeah, we do have a pretty busy site (apkmirror.com), and it caused a disruption for any uploads or downloads from that server until I woke up and fixed the mount.

I wish I could be more helpful but all I have is that stack trace. 

I'm glad it's a blocker and will hopefully be resolved soon.

Hi Artem,

Opened https://bugzilla.redhat.com/show_bug.cgi?id=1671603 (ie, as a clone of other bugs where recent discussions happened), and marked it as a blocker for glusterfs-5.4 release.

We already have fixes for log flooding - https://review.gluster.org/22128, and are the process of identifying and fixing the issue seen with crash.

Can you please tell if the crashes happened as soon as upgrade ? or was there any particular pattern you observed before the crash.

Do the pending patches fix the crash or only the repeated warnings? I'm running glusterfs on OpenSUSE 15.0 installed via http://download.opensuse.org/repositories/home:/glusterfs:/Leap15-5/openSUSE_Leap_15.0/, not too sure how to make it core dump.

If it's not fixed by the patches above, has anyone already opened a ticket for the crashes that I can join and monitor? This is going to create a massive problem for us since production systems are crashing.

Thanks.

Sincerely,
Artem

I'm hoping raising the issue here on the mailing list may bring some additional eyeballs and get them both fixed.

I found a similar issue here: https://bugzilla.redhat.com/show_bug.cgi?id=1313567. There's a comment from 3 days ago from someone else with 5.3 who started seeing the spam.

Here's the command that repeats over and over:

+Milind Changire Can you check why this message is logged and send a fix?


Is there any fix for this issue?

Thanks.
