[Gluster-users] Volume creation fails with "prefix of it is already part of a volume"

[Daniel Müller]

Are you running with gluster 3.4?
I had the same issue. I solved it by deleting my subfolders again and then
create new ones. In your case brick1 and brick2.
Then create new subfolders in the place,ex.: mkdir /mnt/bricknew1  and
/mnt/bricknew2 .
This solved the problem for me, not knowing why gluster 3.4 behave like
this.
Good Luck

Betreff: [Gluster-users] Volume creation fails with "prefix of it is already
part of a volume"

Hi All,

I'm setting up a small test cluster: 2 nodes (gluster-node1 and
gluster-node4) with 2 bricks each (/mnt/brick1 and /mnt/brick2) and one
volume (vol_icclab). When I issue the create volume command I get the
following error:

# gluster volume create vol_icclab replica 2 transport tcp
gluster-node4.test:/mnt/brick1/vol_icclab
gluster-node1.test:/mnt/brick1/vol_icclab
gluster-node4.test:/mnt/brick2/vol_icclab
gluster-node1.test:/mnt/brick2/vol_icclab
volume create: vol_icclab: failed: /mnt/brick1/vol_icclab or a prefix of it
is already part of a volume

I checked and found this [1], but in my case the issue it's happening when
creating the volume for the first time, not after removing/adding a brick to
a volume.

Any suggestions?
