Volume creation fails with "prefix of it is already part of a volume"

Hi Anand,

See output below. gluster-node4 is where I execute the create volume command.

On gluster-node1:
> getfattr -d -e hex -m . /mnt
getfattr: Removing leading '/' from absolute path names
# file: mnt
security.selinux=0x73797374656d5f753a6f626a6563745f723a6d6e745f743a733000

> getfattr -d -e hex -m . /mnt/brick1
> getfattr -d -e hex -m . /mnt/brick1/vol_icclab
> getfattr -d -e hex -m . /mnt/brick2
> getfattr -d -e hex -m . /mnt/brick2/vol_icclab

On gluster-node4:
> getfattr -d -e hex -m . /mnt
getfattr: Removing leading '/' from absolute path names
# file: mnt
security.selinux=0x73797374656d5f753a6f626a6563745f723a6d6e745f743a733000

Please provide the output of the following commands on the respective nodes:

on gluster-node1 and gluster-node4:

getfattr -d -e hex -m . /mnt
getfattr -d -e hex -m . /mnt/brick1
getfattr -d -e hex -m . /mnt/brick1/vol_icclab
getfattr -d -e hex -m . /mnt/brick2
getfattr -d -e hex -m . /mnt/brick2/vol_icclab

Thanks,

Hi Vijay,

I did saw the link you posted, but as mentioned earlier I get this error
when creating the volume for the first time, not when I try to remove and
then re-add a brick to a volume.

Thanks,
