about samba failover
Hi all,
As many of us, I'm trying to find a way to have a failover solution for
a Samba domain.
The actual choice has been (because of hardware cost) to have only 1
physical xen-based server (ubuntu 14.04) that do (dom0) :
- DHCP server (LAN)
- NTP server
- firewall
- proxy
- DNS server
Then 4 VMs running for:
- Samba Domain controller
- Samba Domain member (file server)
- Apache2 server

GlusterFS, Pacemaker, OCF resource agents on CentOS 7
Hi guys
I'm wondering if anyone here is using the GlusterFS OCF
resource agents with Pacemaker on CentOS 7?
yum install centos-release-gluster
yum install glusterfs-server glusterfs-resource-agents
The reason I ask is that there seem to be a few problems
with them on 3.10, but these problems are so severe that I'm
struggling to believe I'm not just doing something wrong.

Dovecot cluster using GlusterFS
Hello,
I have recently setup mailserver solution using 2-node master-master
setup (mainly based on MySQL M-M replication and GlusterFS with 2
replica volume) on Ubuntu 14.04 (Dovecot 2.2.9).
Unfortunately even with shared-storage-aware setting:
mail_nfs_index = yes
mail_nfs_storage = yes
mail_fsync = always
mmap_disable = yes

High availability for guests
Hello,
What is the recommended way to offer high availability to Guests?
For example, let host1, host2 and host3 be libvirt and KVM/Qemu enabled.
If I start a guest in host1, how can I guarantee that it will stay
online if host1 goes down?
GlusterFS, for example, would take care of storage; but what about CPU
and RAM? How can this be accomplished?
Thank you for any feedback or comment in

Samba/GPFS/GlusterFS
Hello,
sorry for this little OT post.
In my company, we have 2
distant facilities, with people at each facility working on the same
files.
The 2 facilities are connected through MPLS with about
10MBytes/s BW.
Saving the work files to servers located at one or the
other facility has became a pain for the people accessing the files from
the remote site.

any recent experience combining GlusterFS w/ Xen?
Hi Folks,
Anybody have any recent experience building a small cluster that
combines GlusterFS and Xen (with bonus points for a Debian environment)?
We''re getting ready to shift from a 2-node Xen/Pacemaker/DRBD
environment to a 4-node environment - and I''d really like to be able to
create/migrate/failover/delete VMs transparently across all 4 nodes.
Seems like Gluster might

how well will this work
Hi Folks,
I find myself trying to expand a 2-node high-availability cluster from
to a 4-node cluster. I'm running Xen virtualization, and currently
using DRBD to mirror data, and pacemaker to failover cleanly.
The thing is, I'm trying to add 2 nodes to the cluster, and DRBD doesn't
scale. Also, as a function of rackspace limits, and the hardware at
hand, I can't separate

Yes. Gluster has it's own quorum, you can disable it but that's just a
recipe for a disaster.

I think so, but I never took the chance so who knows.

I think you are talking about DRBD 8, which is indeed very easy. DRBD 9
on the other hand, which is the one that compares to gluster (more or
less), is a whole other story. Never managed to make it work correctly
either

GlusterFs - Any new progress reports?
GlusterFs always strikes me as being "the solution" (one day...). It's
had a lot of growing pains, but there have been a few on the list had
success using it already.
Given some time has gone by since I last asked - has anyone got any more
recent experience with it and how has it worked out with particular
emphasis on Dovecot maildir storage? How has version 3 worked out for

Exorbitant cost to achieve redundancy??
I'm trying to justify a GlusterFS storage system for my technology
development group and I want to get some clarification on
something that I can't seem to figure out architecture wise...
My storage system will be rather large. Significant fraction of a
petabyte and will require scaling in size for at least one decade.

GlusterFS replica question
Hi,
For small lab environment I want to use GlusterFS with only ONE node.
After some time I would like to add the second node as the redundant
node (replica).
Is it possible in GlusterFS 3.1 without downtime?

GlusterFS & XenServer Baremetal
Hello,
What is for you the best GlusterFS scenario in using XenServer (i'm not
talking about Xen on a linux but XenServer baremetal) for a web farm
(Apache-Tomcat) ? I were thinking of using ZFS as the filesystem for the
different nodes.
The objectives/needs :
* A storage cluster with the capacity equal to at least 1 node(assuming all
nodes are the same).
* being able to lose/take down any

GlusterFS 3.4 Fuse client Performace
Dear GlusterFS Engineer,
I have questions that my glusterfs server and fuse client
perform properly on below specification.
It can write only *65MB*/s through FUSE client to 1 glusterfs server (1
brick and no replica for 1 volume )
- NW bandwidth are enough for now. I've check it with iftop
- However it can write *120MB*/s when I mount nfs on the same volume.
Could anyone check if the
