[Gluster-users] NFS problems with 3.1.1

I'm having I/O errors on my clients who are mounting 3.1.1 via gluster
native NFS. The clients are running NGINX.

Any advice appreciated! Perhaps my access mode is incorrect for nfs?

The throughput is about 20Mbps sustained, but the system benched at
about 600-900Mbps so that shouldn't be a problem.

Errors along the lines of:
2010/12/22 08:09:32 [alert] 12206#0: *5807333 sendfile() failed (5:
Input/output error) while sending
which matches to:
[2010-12-22 16:07:36.937671] I [dht-common.c:369:dht_revalidate_cbk]
pool-dht: subvolume pool-client-1 returned -1 (Invalid argument)

(one system is gmt, the other pst)

- NFS in fstab on clients: /gfs1 nfs

- GFS configuration:
2 nodes running ubuntu 10.04.1LTS
1 brick per node consisting of EXT4+LVM on two RAID1 2TB drives (total
of 2TB per node)
- GFS create line:

- Access mode:
