It's my pleasure, CC devel to confirm this issue.
Thank you for your help!It seems that it is my fault, I didn't disable quota and enable it again, so it seems work fine on commits before 2fb445ba, when you write file to a volume which had already reached its usage limit, it tells Disk quota exceeded. But actually, on former commits(before 2fb445ba), if I disable quota and enable it again, the volume is crash. You are right! 2fb445ba addressed the quota issue!
Thank you very much!!

_______________________________________________Hi, PSC
We encounter the same issue a few month ago, and git bisect says the first bad commit is 2fb445ba. This patch is not quota related, but it addressed the quota issue!
Maybe it's gcc issue??

syncop: remove unnecessary call to gf_backtrace_save()
A call to gf_backtrace_save() was done on each context switch of a
synctask. The backtrace is generated writing to the filesystem, so it
can have an important impact on latency.
The generated backtrace was not used anywhere, so it's been removed.

Hi, I am studying on port glusterfs to ARM platform. I compiled and ran it. Most of its functions works fine, however, when I enable quota on any kind of volume, and mount it, and try to read or write anything to the volume. It will run into crash, and tell me the "Transport endpoint is not connected".
The version of glusterfs I am using is GlusterFS 3.12.2.And I test it from version 3.12.2 to 6.0. This problem was solved on 6.0, but I didn't found any addressed Bugs relate to quota.I also do some test on x86 servers, quota works fine.
On both of x86 and ARM servers, I am using CentOS 7.6.
For stability reason, I had been told that I should use GlusterFS 3.12.2, rather than new versions. So I need to find out how to address this bug.
Please offer me some help. Thank you very much!!
