does libgfapi and fuse mount performance matches?
Dear gluster experts, I recently want to use jna to bind libgfapi to java. And I have one question. Does libgfapi and fuse mount performance match? The performance translators works for libgfapi too? Thank you very much. -- ???

Possible to use libgfapi with libvirt in CentOS 6.5?
Good Evening, I have read that libgfapi has been backported to qemu-kvm in RHEL 6.5 (and by virtue CentOS and SL). However I am unable to figure out how to actually make it work as described. Virt-manager still only seems to support glusterfs volumes via fuse. I can use qemu-img to create a disk image on gluster://<server>/<Volume>. But virt-manager can only use it from a fuse

libvirt and libgfapi in RHEL 6.5 beta
Dear All, Very pleased to see that the Redhat 6.5 beta promises "Native Support for GlusterFS in QEMU allows native access to GlusterFS volumes using the libgfapi library" Can I ask if virt-manager & libvirt can control libgfapi mounts? :) or do I need to use ovirt? :( many thanks Jake

libgfapi disk locking in virtlockd not working
Hello. I'm playing with libgfapi network disks, over IB and all is working fine, but not disk locking (and true rdma transport). I use virtlockd, and with fuse mount, locking works as expected. But when i converted disk definitions to libgfapi, locks are not created (but qemu starts and works fine). I used direct and indirect locking - same result : qemu working fine, no locks. my

libgfapi with encryption?
Hi, I created an encrypted volume which appears to be working fine with FUSE but the volume is supposed to store VM images (master key in place). I noticed some references in libgfapi source code to encryption so I decided to try it out. While attempting to create an image: # qemu-img create -f qcow2 gluster://gluster01/virt0/testing.img 30G Formatting

libgfapi failover problem on replica bricks
Hello, I'm having an issue with rebooting bricks holding images for live KVM machines (using libgfapi). I have a replicated+distributed setup of 4 bricks (2x2). The cluster contains images for a couple of kvm virtual machines. My problem is that when I reboot a brick containing a an image of a VM, the VM will start throwing disk errors and eventually die. The gluster volume is made like

High Guest CPU Utilization when using libgfapi
Hi, I am currently testing running Openstack instance on Cinder volume with libgfapi. This instance is the Windows instance and i found that when running random 4k write workload, the CPU utilization is very high, 90% CPU utilization with about 86% in privileged time. I also tested the workload with volume from NFS and the CPU utilization is only around 5%. For gluster fuse, the CPU utilization

quadratic programming-maximization instead of minization
Hi, I need to maximize a quadratic function under constraints in R. For minimization I used solve.QP but for maximization it is not useful since the matrix D of the quadratic function should be positive definite hence I cannot simply change the sign. any suggestion ? thanks -- View this message in context:

Software versus hardware RAID performance.
With the Dell OpenManage question on my mind (and having seen it answered very well), I was reminded of an interesting and a little surprising thing I saw yesterday. I upgraded a PowerEdge 2850 from CentOS4 to Fedora Core 5 (keeping everything updated for GNUradio to run on CentOS 4 became more of a job that it should have) for our pulsar data processing machine (it has a GNUradio Universal

Adding Gluster support for Primary Storage in CloudStack
Hi all, I'd like to inform any CloudStack users that there are now patches [0] available (for CoudStack) that make it possible to use an existing Gluster environment as Primary Storage on CloudStack. The changes extend CloudStack so that libvirt will be used for mounting the Gluster Volume over the fuse-client. Some further details and screenshots are available on my blog [1]. If there
