[Gluster-users] how to check/fix underlaying partition error?

[Pavel Riha]

Thank you for your reply.

but btw what is the right way to do this?
stoping the glusterd service does not stop the glustefsd daemons itself
https://bugzilla.redhat.com/show_bug.cgi?id=988946

and I have more volumes running, but only one with this problem.
I haven't found any official way how to stop the process, so I just 
KILLed them.
It worked.. partiton repaired, seems ok for now.

But how to run the brick again??
I didn't save the cmdline showed in ps, but it was crazy. As I see the 
other running .. there are crazy numbers (uuid, socked, port)
and the port (for ex) is not the same as on the other server...

so I restarted the glusterd service .. nothing happend .. I was hopeless
.. but after a while I recognized, that the process is running, so maybe 
the glusterd started it after a while

there should be some way to stop or at least start one brick
