Hi all, I am using heartbeat and drbd on CentOS 5 (see http://www.centos.org/modules/newbb/viewtopic.php?topic_id=7816&forum=41 for details).. DRBD and heartbeat are working, and now I want to put GNBD on top on this. However, I installed the latest CentOS-plus kernel (2.6.18-8.1.8.el5.centos.plus) but there doesn't appear to be a kmod-gndb for this kernel. Looks like the latest kmod-gnbd is available for kernel 2.6.18-8.1.8.el5. But I cannot find a kmod-drbd for this kernel. Am I missing so...

Hi all, I am trying to configure a failover multipath between 2 GNBD devices. I have a 4 nodes Redhat Cluster Suite (RCS) cluster. 3 of them are used for running services, 1 of them for central storage. In the future I am going to introduce another machine for central storage. The 2 storage machine are going to share/export the same disk. The idea is not to have...

Hi all, Where i want to arrive: 1) having two storage server replicating partition with DRBD 2) exporting via GNBD from the primary server the drbd with GFS2 3) inporting the GNBD on some nodes and mount it with GFS2 Assuming no logical error are done in the last points logic this is the situation: Server 1: LogVol09, DRDB configured as /dev/drbd0 replicated to Server 2. DRBD seems to work perfect as cat /pro...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Up until now, I have been using drbd for file custers with great success. Yes, it is a PITA, and sometimes you can get annoying sincronization issues (mostly on lab situations). Now I have been considering giving gnbd (with cs/gfs) a try. Do any of you ever crossed this path ? Any comparisons or comments ?

hi all.. Is it recommended to use GNBD in production cluster? . The main purpose of this cluster would be to provide high availablity of Xen virtual machines. I don''t have a fencing device hence I am giving a thought to use GNBD since it can be used in fencing without any fencing hardware. Also, any pointers to the tutorial on...

...think these are mirred on centos.org, but I read them off of redhat's site) Basically I currently have two servers. The file server is a dell power edge 2850 with an attached power vault. The power vault's file systems are all gfs. I would like to export these to a second server via gnbd. I realize I *could* use nfs, which we do use elsewhere, but I was interested in figuring out gnbd. On the file server if I run gnbd_export -d /dev/vg_home/lv_home -e home Then on the other server modprobe gnbd and then run gnbd_import -i fileserver the devices get created can be mounted etc...

Anyone have any experience with GNBD? What kind of performance and security differences are there in running GNBD vs NFS? We're planning an implementation with an external storage array (DAS) and want to use a shared filesystem. We have 10 or so clients that will be connecting to the shared filesystem. We have duplic...

...and then export the block devices over the network to the xen hosts? Ideally the goal is to have the effect of shared storage on the xen hosts so that domains can be migrated between them in case one server needs to go offline. Do I run GFS on top of the DRBD mirrored device, exported via GNBD to the xen hosts; or the other way around, using GNBD to export the DRBD mirrored device and then GFS running on the xen hosts? Is this possible; is there an easier/simpler/better way to do it? Thanks, Tom
