You can do that, but you could run into issues with the 'shared'
remaining space. Any one of the volumes could eat up the space you
planned on using in another volume. Not a huge issue, but could bite
you.<br>
<p>I prefer to use ZFS for the flexibility. I create a RAIDZ pool
and then separate zfs filesystems within that for each brick. I
can reserve a specific amount of space in the pool for each brick
and that can be modified as well.<br>
</p>
<p>It is easy to grow it too. Plus, configured right, zfs does
parallel across all the disks, so you get speedup in performance.</p>

<div>Wondering if there is a best practice for volume creation.
I don't see this information in the documentation. For
example.</div>
<div>I have a 10 node distribute-replicate setup with one large

<div>Is it OK for me to have just one xfs filesystem mounted and
use subdirectories for my bricks for multiple volume creation?
</div>
<div>So I could have, lets say 10 different volumes but
each using a brick as subdir on my single xfs filesystem on
each node? </div>
<div>In other words multiple bricks on one xfs filesystem per
node? </div>
<div>I create volumes on the fly and creating new filesystems
for each node would be too much work. </div>

<div>Your thoughts?</div>
