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 />
