Is there a way to use a round-robin or something, as opposed to hash? 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. Can this be avoided?

Is there anything I can do to fix this? Add scheduler? 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....

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