The problem with distribute is that it does not know the disk has run out of space, until it's starting copying and run out of space.<br>
Can this be avoided?<div class="im"><br>

Well currently I've got 4 servers set up.<br>
|- ServerA -AFR-> ServerB<br>
Client -|<br>
|- ServerC -AFR-> ServerD<br>
<br>
I keep copying the same 1GB file to the storage, but it always writes to ServerC no matter what I do. Is there anything I can do to fix this? Add scheduler?<br>
<br>
<br>
<br>
My understanding is that distribute uses a hash to do the distribution. So, if you copy the same file, you will get the same result every time; that is, it will go to the same server every time. Hashing is deterministic in that sense. Vikas or someone else may clarify if I have things wrong here....<br>

Distribute by default will distribute _files_ evenly among its<br>
subvolumes. However, if one of the files is larger than the disk space<br>
available on the node it gets scheduled to, then distribute can do<br>
nothing. If you regularly want to store big files which might not fit<br>
on one of your subvolumes, you might want to try the 'stripe'<br>
translator.<br>
