Re: [Openstack] Openstack] Suggestions for shared-storage cluster file system

So it sounds like what we're talking about here is running a Ceph or GlusterFS node alongside the compute node (ie, on the same physical system). I assume then that VMs access their volumes via NFS or iSCSI from Cinder on the controller node, and in turn, Cinder reads and writes to the cluster FS,

Re: [Openstack] Suggestions for shared-storage cluster file system

We have used Gluster for small deployments, but lately we have changed our mind. Basically we have bet on Gluster for 2013 because of: - 10GbE everywhere, and Gluster MUST run in 10GbE (or Infiniband) - 3.3 release fixes some issues when locking big files: Granular locking - libgfapi reborn, no m

Hey Marco, have you been able to run some performance test on your Gluster cluster?Thanks :) Razique Mahroua - Nuage & Corazique.mahr...@gmail.comTel : +33 9 72 37 94 15 Le 18 févr. 2013 à 14:20, Marco CONSONNI a écrit :Hello Sam,I've tried two of them: NFS and Gluster.Some pr

Re: [Openstack] Suggestions for shared-storage cluster file system

Hello Sam, I've tried two of them: NFS and Gluster. Some problems with the former (migration didn't work properly), no problem with the latter. I vote for Gluster. Hope it helps, Marco. On Fri, Feb 15, 2013 at 4:40 PM, Samuel Winchenbach wrote: > Hi All, > > Can anyone give me a recommendati

Re: [Openstack] Suggestions for shared-storage cluster file system

I haven't played that much with Glusterfs and pacemaker but I'm pretty sure that there is already a resource agent for this. Maybe the Filesystem RA can do it but you probably might have a look at the upstream version on the Cluster Lab Github. Cheers On 15 févr. 2013, at 20:54, Samuel Winch

Re: [Openstack] Suggestions for shared-storage cluster file system

Is there anyone using GPFS (General Parallel Filesystem) from IBM. It's high performing, posix compliant, can do internal replication, etc...? To make it work, would one simply have to modify the nova-volume (or cinder) code that creates a volume-group using the corresponding GPFS commands? Or,

Re: [Openstack] Suggestions for shared-storage cluster file system

Thanks, I think I will go with GlusterFS. MooseFS looks interesting, but maintaining a package outside the repo/cloud archive is not something I want to deal with. Along the same lines... is it possible to mount a GlusterFS volume in pacemaker? I have tried both ocf:heartbeat:Filesystem and

Re: [Openstack] Suggestions for shared-storage cluster file system

Hi, Important: Mount the CephFS filesystem on the client machine, not the > cluster machine. It's just like NFS, if you mount an NFS export on the NFS server, you get kernel locks. Unfortunately even if love Ceph far more than the other, I won't go with CephFS, at least not know. But if are in

[Openstack] Suggestions for shared-storage cluster file system

Hi All, Can anyone give me a recommendation for a good shared-storage cluster filesystem? I am running kvm-libvirt and would like to enable live migration. I have a number of hosts (up to 16) each with 2xTB drives. These hosts are also my compute/network/controller nodes. The three I am consi
