Hi
I've found something that works so weird I'm certain I have missed how
gluster is supposed to be used, but I can not figure out how. This is my
scenario.
I have a volume, created from 16 nodes, each with a brick of the same
size. The total of that volume thus is in the Terabyte scale. It's a
distributed volume with a replica count of 2.
The filesystem when mounted on the clients is not even close to getting
full, as displayed by 'df'.
But, when one of my users try to copy a file from another network storage
to the gluster volume, he gets a 'filesystem full' error. What happened? I
looked at the bricks and figured out that one big file had ended up on a
brick that was half full or so, and the big file did not fit in the space
that was left on that brick.

Hi,
This is working as expected. As files are not split up (unless you are
using shards) the size of the file is restricted by the size of the
individual bricks.
</blockquote>
Thanks a lot for that definitive answer. Is there a way to manage this?
Can you shard just those files, making them replicated in the process?

My thinking on this is a RAID 10 with the RAID 0 in the lvm and the RAID1 handled by gluster replica 2+ :-)</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><pre>
I just can't have users see 15TB free and fail copying a 15GB file. They
will show me the bill they paid for those "disks" and flay me.
