Gluster users - Mar 2014 - Bring up a brick after disk failure

Hi,



One of my bricks suffered from complete raid failure, (3 disks on raid6). I
created a new raid, and wanted to bring the brick back up in the volume. Did the
following

1. Removed it with

gluster volume remove-brick gluster s1:/mnt/raid6 start

gluster volume remove-brick gluster s1:/mnt/raid6 commit




2. Detached with

gluster peer detach s1




3. Probed anew:

gluster peer probe s1




4. Tried to add with

gluster volume add-brick gluster s1:/mnt/raid6




But last one fails with

Stage failed on operation 'Volume Add brick'




I'm using 3.4.2.




Thanks,




/jon

I managed to add the brick by using the "force"-flag, i.e.,


"gluster volume add-brick gluster s1:/mnt/raid6 force"

Hopefully there are no drawbacks involved with this...

WARNING: I'm not even sure if this is true, or if I changed something else, 
but I give you my experience to try.

I was having trouble adding an additional brick to my replica array, and I 
was getting the same (or a similar) message.  I then tried adding the brick 
from the command line on the machine where the brick is located.  All of the 
sudden I began to get meaningful error messages.  As far as I know, the only 
thing I changed was which computer I sshed into, but it made all the 
difference in the world. The error messages were quite specific, and easy to 
understand.

I am curious if others have experienced the same thing.
