[Gluster-users] ovirt read error

Hi all,

I am stuck with a strange problem using ovirt/gluster on ZFSonLinux.

I detached a data-volume form my Cluster an reimported it to change
from POSIX-type/glusterfs to GlusterFS-Storage. When I try to attach it
to the Cluster I always get a Sanlock error. I checked the logs and what I found were some "operation not permitted"
errors in the brick logs:

[2016-07-08 09:19:24.542046] E [MSGID: 113040] [posix-
helpers.c:1684:__posix_fd_ctx_get] 0-datadom-posix: Failed to get

(c1433bab-cd72-4395-ac62-b278670c333a) ==> (Operation not permitted)
[Operation not permitted]

Anyone ever expierienced such problem?

In fact I am able to create/change/delete files in the brick path
itself and the mount points (NFS/Fuse).
Ovirt itself seems to test the volumes with /usr/bin/dd, but uses
iflag=direct. Using this parameter I'm also unable to create any file -
is there any gluster-option that changed recently? Or is it ZFS, that
introduced something that blocks now?

Thanks in advance, Frank
