Hi,
Yes, they do, and considerably. I'd forgotten to mention that on my
last email. Their mtimes, however, as far as i could tell on separate
servers, seemed to coincide.
Thanks,

Are these files always open? And is it possible that the file could have
been renamed when one of the bricks was offline? I know of a race which
can introduce this one. Just trying to find if it is the same case.

hi,
Could you see if the size of the file mismatches?

Hi everyone,
I have this really confusing split-brain here that's bothering me. I
am running glusterfs 3.4.2 over linux 2.6.34. I have a replica 2
volume 'testvol' that is It seems I cannot read/stat/edit the file in
question, and `gluster volume heal testvol info split-brain` shows
nothing. Here are the logs from the fuse-mount for the volume:

Could somebody please give me some clue on where to begin? I checked
the xattrs on
/SECLOG/20140908.d/SECLOG_00000000000000427425_00000000000000000000.log
and it seems the changelogs are [0, 0] on both replicas, and the
gfid's match.
Thank you very much for any help on this.
