Hi. The short story... Rush job, never done clustered file systems before, vlan didn't support multicast. Thus I ended up with drbd working ok between the two servers but cman / gfs2 not working, resulting in what was meant to be a drbd primary/primary cluster being a primary/secondary cluster until the vlan could be fixed with gfs only mounted on the one server. I got the single server

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

Hello, I assign IP 172.25.0.1 and 172.25.1.1 on one interface of my router. This interface is connected to local LAN switch. If I ping from my box on lan with IP 172.25.0.22 I get icmp reply, but if I assig to my box IP 172.25.1.22 I don''t get icmp reply. My setup: ip addr add 172.25.0.1/24 brd + dev eth0 ip addr add 172.25.1.1/24 brd + dev eth0 kernel 2.4.3, iproute2-current,

Two web servers, both virtualized with CentOS Xen servers as host (residing on two different physical servers). GFS used to store home directories containing web document roots. Shared block device used by GFS is an ISCSI target with the ISCSI initiator residing on the Dom-0, and presented to Dom-U webservers as drives. Also, providing a second shared block device for quorum disk. If I hit the

Hi, I have configured two machines for testing gfs filesystems. They are attached to a iscsi device and centos versions are: CentOS release 5.4 (Final) Linux node1.fib.upc.es 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 i686 i386 GNU/Linux The problem is if I try to mount a gfs partition it hangs.

Hi, I'm trying to get more performance out of my DRBD cluster with gfs2. It seems that our gfs2 implementation is quit slow. When running the ping_pong test we get no more than a 1000 locks/sec on the disk. ./ping_pong /mnt/backup/test.dat 4 879 locks/sec The cluster config has been updated with: <dlm plock_ownership="1" plock_rate_limit="0"/>

Hello, maybe there is someone they can help and answer a question why i get these network screen on my ctdb clusters. I have two ctdb clusters. One physical and one in a vmware enviroment. So when i transfer any files (copy) in a samba share so i get such network curves with performance breaks. I dont see that the transfer will stop but why is that so? can i change anything or does anybody know

We have done some benchmarking tests using dovecot 2.0.12 to find the best shared filesystem for hosting many users, here I share with you the results, notice the bad perfomance of all the shared filesystems against the local storage. Is there any specific optimization/tunning on dovecot for use GFS2 on rhel6??, we have configured the director to make the user mailbox persistent in a node, we will

Dear List, I have one last little problem with setting up an cluster. My gfs Mount will hang as soon as I do an iptables restart on one of the nodes.. First, let me describe my setup: - 4 nodes, all running an updated Centos 5.2 installation - 1 Dell MD3000i ISCSI SAN - All nodes are connected by Dell?s Supplied RDAC driver Everything is running stable when the cluster is started (tested

Hi everybody, as discussed and agreed at the Cluster Summit we need to split our tree to make life easier in the long run (etc. etc.). We need to decide how we want to do it and there are different approaches to that. I was able to think of 3. There might be more and I might not have taken everything into consideration so comments and ideas are welcome. At this point we haven't really
