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.
