Hi,
If the file creation hashes to the brick which is down, then it fails with ENOENT.

Subject: Writing to distributed (non-replicated) volume with failed nodes
Hi,
I have an 8-node trusted pool with a distributed, non-replicated volume
The bricks are located only on 2 machines (2 bricks per node), so there are 6
dummy" nodes. Everything is working great until one of the brick-arrying nodes
experiences a power outage.
In this case, I can still mount the volume after a timeout (there is
plenty of servers to ask for metadata, after all) and read files from there,
but whenever I try to create a random-named file (e.g. running touch
/mnt/.lock-${RANDOM}${RANDOM}) this succeeds only sometimes, but often fails
with "no such file or directory". I understand that error if I were touching
files that already exist on the offline node (but invisible with the degraded
volume), but these are new random files which never existed before.
So, why does writing to the online bricks fail, and what can I do to
enable it? The machines run fully up-to-date Fedora 22 and ArchLinux with
gluster 3.7.4. I tried to look for similar problems on this ML, but haven't
found anything related, sorry if I missed something.
Thanks!
L.
