Hi,
Thanks for your help thus far. I'm continuing my testing and have run
across some errors in my logfiles. I'm using rsync from a local
directory to the gluster volume to load up some test data. This is
the only processing modifying the gluster filesystem. Occasionally,
I'll see self-heals triggered while the the rsync is running. With
the exception of this one, they all finish without any errors reported.
I thought it was strange that selfheals were being triggered since all
of the servers are up and rsync is the only process modifying the
gluster filesystem, but since it seemed harmless I ignored them.
This time it seemed to be more of an error. While rsync is copying
files, it uses a different filename than the file that's actually
being copied, and once the copy is complete, the file is renamed to
it's original name. There seems to have been a race condition here
where a self-heal is triggered and during that time, the file is
renamed. The logs on brick1 and brick3 seem consistent with this
theory. The failed locks seem to make sense also with the error "No
such file or directory" (the old name is no longer in use). I see 2
potential problems here. The first is that self-heals are
occasionally being triggered during a copy when everything is up and
functioning properly. The 2nd issue seems to be that during a self-
heal, there is a race condition where a file can be renamed and causes
these errors below.
Running 1.4RC3, logs and volfiles are below. Nothing of mention was
in glusterfs.log except on brick1. Please let me know what i can do
to help.
