Hello,<br>
<br>
I have currently 2 bricks which are with AFR config.<br>
<br>
My plans are when I fill the available space, to add 2 new bricks which<br>
are in AFR too.<br>
<br>
My question is: is it possible to migrate from my current setup 2 bricks<br>
AFR to UNIFY over AFR by adding another 2 AFR bricks, without loosing data?<br>
</blockquote><div><br>If the new afr you are adding is empty (it does not contain any data), you can do so. Other wise you've to confirm that a file is present in exactly on one afr node.<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>
Some clarifications, the setup is not yet in production. If I can do<br>
something which will make things easier later, I can do it now. I am<br>
able to start from scratch, but later I will not be ;).<br>
<br>
The other question that pops up is: Is glusterfs able to handle the<br>
situation when one of the AFR volumes in the UNIFY setup is full and the<br>
other is not ?</blockquote><div><br>Yes. Unify schedulers have configuration options, where in you can configure the parameters like minimum available space for a file to be created on an unify child.<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
