<br>
1. While learning GlusterFS, I'was wondering if it's possible to add<br>
server volumes to increase space capacity of my cluster "on the FLY"?<br>
I mean, a hot upgrade.<br>
</blockquote><div><br>Hope you checked the Roadmap, we have it coming in 1.5 release (planned to it ready by yearend).<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
2. Second, when using "files replicating strategy" (scheduler), is it<br>
possible to remove a server node without stopping the hole cluster<br>
(ex. hardware maintaining reasons, add more disk/ram to the node ...)?<br>
</blockquote><div>Scheduler is not the term you may be looking at... check AFR (automatic file replication), and yes, if you are using, you can take out the node when cluster is active.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
3. Finally, what's the best volume specifications for writing huge<br>
number (hundred thousands) of big file (1 Gb size in average) on my<br>
cluster?<br>
I've an application which produce these big files at a regular rate<br>
(let say, 1 file per minute) and I'd like to know if a good volume<br>
scpecification<br>
can handle this amount of data?<br>
</blockquote><div><br>Well, at the rate of 1GB per minute, you will hit the disk speed, hence stripe is better option. But with Stripe translator you will not be able to take out the nodes. <br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
Examples will be very welcome guys.<br>
<br>
Thanks in advance.<br>
<br>
cheers<br>
F.<br>
