Hi ,<br>
<br>
We are using GlusterFS in our product for DFS. We have found an
issue in using "striping" while experimenting with Striped Volumes
in our DFS infrastructure. We thought of enable striping to support
"Max Files Size" when a file dynamically grows/shrink over time
inside a brick. We need to add more storage dynamically to handle
this situation and striped the file across bricks to fit it properly
in that striped volume .<br>
<br>
<b>Question</b>: is Does Gluster supports "dynamic configuration
of Stripe Count" (increment / decrement stripe count) of Striping
currently ?<br>
<br>
We tried with following two basic experiments :<br>
<br>
1. Create a volume with two bricks with stripe count 2 with no
replica ( to simplify ).<br>
<br>
2. Add one more brick in that volume and increase stripe count by
one ( the stripe count becomes 3 now) .<br>
- Seems it works fine and files are being striped across 3
bricks as per specified chunk-size .<br>
<br>
3. However faced issues while removing a brick from the volume and
decrement stripe count by one again ( so the stripe count becomes 2
again)<br>
=> Gluster is not allowing to reduce the stripe count in this
scenario.<br>
<br>
Could you please help us by clarifying this. <br>
<br>
Thanks for your help <br>
<br>
