CHANGE: http://review.gluster.org/3849 (storage/posix: implement native linux AIO support) merged in release-3.3 by Vijay Bellur (vbellur)

I've just upgraded to 3.3.1-8.fc18 and I now get Fsync failures when saving files when storage.linux-aio is activated:

[root@recon glusterfs]# gluster vol info

Volume Name: md0
Type: Distribute
Volume ID: ef96e861-ffa7-4db9-bdc8-528e3e2941bc
Status: Started
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: 169.254.0.1:/mnt/md0/brick1
Options Reconfigured:
storage.linux-aio: on
auth.allow: 169.254.*
nfs.disable: on


I tried to save a file in vi and got this error:

"test" E667: Fsync failed

I see this in the logs:

I can "touch" files ok, but not save anything with content. For example, if file "test" doesn't exist and I do "echo > 1 test" the file is created but its empty.
