Help-
I have multiple gluster filesystems, all with the setting:
cluster.min-free-disk: 500GB. My understanding is that this setting should
stop new writes to a brick with less than 500GB of free space. But that
existing files might expand, which is why I went with a high number like 500GB.
But I am still getting full bricks, frequently it's the first brick in the
cluster that suddenly fills up.
Can someone tell me how gluster chooses where to write a file. And why the
min-free-disk is being ignored.
Running 3.3.1 currently on all servers.
Thanks,

Make sure you are running 3.3.1 also on all the clients also. It is
determined by the clients. I noticed there is a fix there is in 3.3.1
which is not in 3.3.0. In 3.3.0, it will try writing to the next brick
which is the 1st brick, but only check if it is not 100% (completely)
free. If it has 1 byte left, it will start writing to it, and that's why
the 1st brick will get filled up.
