How to format a gluster brick using the same xfs parameters

Issue

In some scenarios we may want to reuse the bricks that belong to a gluster volume, and we need to recreate a new xfs filesystem on the existing brick using the same parameters as when the brick was initially created.

Note1 This document assume the data on the gluster volume is not valid, and that the gluster volume can be deleted.
Note2 The deletion of the volume does not destroy the data on the bricks.
Note3Formating the brick will destroy all the existing data on that brick.

On this example we will format brick1 of the following volume:

Volume Name: myvol
Type: Replicate
Volume ID: 33364d5d-de3d-4290-b73c-a2b344188432
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x 3 = 3
Transport-type: tcp
Bricks:
Brick1: gluster-0:/mnt/data1/1
Brick2: gluster-1:/mnt/data1/1
Brick3: gluster-2:/mnt/data1/1

The brick filesystem based on device /dev/mapper/vg1-lv1 is mounted on /mnt/data1 as here:

[root@gluster-0 ~]# df -k
Filesystem          1K-blocks    Used Available Use% Mounted on
/dev/mapper/vg1-lv1  10418176   33956  10384220   1% /mnt/data1

If we try to format the brick with parameters that are not the same as the used initially to create the brick, we may get an error like this:

[root@gluster-0 ~]# mkfs.xfs -f -i size=512 -n size=8192 -d su=128k,sw=10 /dev/mapper/vg1-lv1
