--- Comment #5 from Xavi Hernandez <jahernan at redhat.com> ---
Which node did you reboot before seeing those errors ? at what time was the
node rebooted ?

What I see from the data you posted is that glfs-node13.avp.ru and
glfs-node25.avp.ru were doing a heal at some point (probably at the time of
reboot, but I'm not completely sure yet). This is ok because your configuration
allows 2 bad bricks, but we have another node with mismatching data:
glfs-node19.avp.ru.

This is what is causing the EIO error, since we have 3 failures but a maximum
of 2 are allowed.

We can try to determine if one of the mismatching versions is good enough to be
considered as good and recover the file.

I still need to check the logs to see if there's more information. Meantime,
knowing which node was rebooted and at what time will be very useful to analyze
the logs.
