Thanks for providing the information Alessandro. We will fix this
issue. I am wondering how we can unblock you in the interim. There
is a plan to release 3.7.1 in 2-3 days I think. I can try to make
this fix for that release. Let me know if you can wait that long?
Another possibility is to compile just glfsheal binary with the fix
which "gluster volume heal <volname> info" internally. Let me
know.<br class="">

Are you sure the attached log is correct? I do not see any
backtrace in the log file to indicate there is a crash
:-(. Could you do "grep -i crash /var/log/glusterfs/*" to
see if there is some other file with the crash. If that
also fails, will it be possible for you to provide the
backtrace of the core by opening it using gdb?<br class="">

So, it seems like the files to be healed are

Also, every time I issue a "gluster volume
