[Gluster-users] Slow write times to gluster disk

Hi Soumya,

We just had the opportunity to try the option of disabling the
kernel-NFS and restarting glusterd to start gNFS.  However the gluster
demon crashes immediately on startup.  What additional information
besides what we provide below would help debugging this?

Thanks,

Pat

*To disable kernal-nfs and enable nfs through Gluster we:*


gluster volume set data-volume nfs.export-volumes on
gluster volume set data-volume nfs.disable off

/etc/init.d/glusterd stop


service nfslock stop

service rpcgssd stop

service rpcidmapd stop

service portmap stop

service nfs stop


/etc/init.d/glusterd stop




*the /var/log/glusterfs/nfs.log immediately reports a crash:*
