<p dir="ltr">Thanks for the hint about force", I didn't try that.<br>
On the other side I am thankful for the error/warning which prevented me to create the volume because I just thought of a scenario which could result in problems.</p>
<p dir="ltr">Imagine you have a LV you want to use for the gluster volume. Now you mount this LV to /mnt/gluster1. You do this on the other host(s), too and you create the gluster volume with /mnt/gluster1 as brick. <br>
By mistake you forget to add the mount entry to fstab so the next time you reboot server1, /mnt/gluster1 will be there (because it's the mountpoint) but the data is gone (because the LV is not mounted).<br>
I don't know how gluster would handle that but it's actually easy to try it out :) </p>
<p dir="ltr">So using a subfolder within the mountpoint makes sense, because that subfolder will not exist when the mount of the LV didn't happen.</p>
