[Gluster-users] Gluster on ZFS: cannot open empty files

Hi everyone,

I've got glusterfs-server/glusterfs-client
version 3.4.0final-ubuntu1~precise1 (from the semiosis PPA) running on
Ubuntu 13.04. I'm trying to share ZFS (ZFS on Linux  0.6.2-1~precise from
the zfs-stable PPA) using GlusterFS. When creating the ZFS filesystem and
the Gluster volume, I accepted all the defaults and then:

- I enabled deduplication for the ZFS filesystem (zfs set dedup=on)
- I enabled quota for the Gluster volume (gluster volume quota
<volume-name> enable)

On the server, I can cd into the ZFS filesystem and open empty files
without problems. However, when I mount the Gluster volume on a remote
machine, I find that I can't open any empty files. Errors show up in the
Gluster log, and they are (I inserted the <volume-name> in place of the
volume's name):

[2013-10-01 19:32:52.125149] W [page.c:991:__ioc_page_error]
0-<volume-name>-io-cache: page error for page = 0x7f944ba2e4a0 & waitq =
[2013-10-01 19:32:52.125180] W [fuse-bridge.c:2049:fuse_readv_cbk]
0-glusterfs-fuse: 2278: READ => -1 (Operation not permitted)

Any ideas about how I can fix this?
