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 -

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. I created

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

Hello GlusterFS users, can anybody give me please his opinion about the following facts and questions: 4 storage server with 16 SATA bays, connected by GigE: Q1: Volume will be set up as distributed-replicated. Maildir, FTP Dir, htdocs, file store directory => as sub dir's in one big GlusterVolume or each dir in it's own GlusterVolume? Q2: Set up the bricks as a collection of

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. Trying to improve files

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

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 ..I have hit strange issues pretty soon especially when user was

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 -------------- next part

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

Anyone using either Glusterfs or DRBD in their mail setup? How is performance, manageability? Problems? Tips? Ed W

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

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

Hi there, Yesterday I've updated from 7 to 7.1 and today I've noticed on 2 server that postgresql systemd file was replaced with default values. This make postgres to no start and webserver give me problem. This problem was fixed and now all works good. It's normal that on major update I can get this problem? If so, I've ridden release change but I have not ridden about

Gluster has it's own quorum, you can disable it but that's just a recipe for a disaster. > Also, on a two-node setup it is *guaranteed* for updates to one node to > put offline the whole volume? I think so, but I never took the chance so who knows. > On the other hand, a 3-way

I have a setup with multiple hosts, each of them are administered separately. So there are no unified uid/gid for the users. When mounting a GlusterFS volume, a file owned by user1 on host1 might become owned by user2 on host2. I was looking into POSIX ACL or bindfs, but that won't help me much. What did other people do with this kind of problem? -------------- next part -------------- An
