Gluster users - Dec 2014 - Sudden interference between 2 independent gluster volumes

Hi all,

Since the strange "hickup" I had on Monday (files disappearing from
the
volume, although existing on the bricks), another very strange (and
horrible) thing happened:

Out of the blue, gluster "Volume-A" is now pointing to the bricks of
another, completely separate and independent "Volume-B".
Ouch! O.o

Running "gluster volume info volume-a" and the same for
"volume-b", both
list the bricks of "volume-b". They even show the identical volume ID.


Regardless of "why" that happened, does anyone here have any idea how
I
can properly fix this and separate the volumes again?


I'm very grateful for any help!
Thanks in advance,
Peter

This is actually directly related to my problem is mentioned here on Monday:
"Folder disappeared on volume, but exists on bricks."

I probed node "A" from server "B", which caused all this. My
bad.
:(


No data is lost, but is there any way to recover the volume information in
/var/lib/glusterd on server "A", to separate it from "B"
again?


Thank you very much in advance,
Pb
