Dear Experts, One of our client wants to use OCFS for their 9i RAC(2 node) on RHEL3 and also use GFS on the nodes. Would there be any issues using OCFS for Oracle 9i RAC and using GFS for failing over things like print services on the same node? Has this been tested? I know these are competing products and OCFS 2.0is not an option now for the client. They need GFS for their custom apps. Any ideas

Has anyone managed to combine bridged network model and SNAT? I have a machine that just ssh''s into other boxes and updates via rsync a copy of their filesystems. I figured I could stage a xen VM for this server with a private IP address and do SNAT and "routing" via the dom0 box, but I get a wierd "Performing cross-bridge DNAT requires IP forwarding to be enabled"

Hi, Irecently setup a Oracle 10g RAC test environment with two HP/Compaq DL380s and a shared disk array. The array is presented as a single 136GB disk. The systems are running RedHat AS 3.0 Update 4. OCFS 1.0.13-PROD1 build: 5e87201061935f464cf6541c56eb2827 Oracle 10g 10.1.0.3.0 I was able to get everything working, had a database created and running an instance on each system. The

I ran into an interesting/strange issue today. I still don''t understand what happened, but in know what fixed it. I had a situation where I could only see vblade exported devices from OFF the physical machine. It seemed that if the packets went through two ports of the bridge (instead of one port and the real interface) they got "lost". I sniffed around and failed to

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

To try and recreate your setup we put an old 3ware controller in a machine with 6GB and have been hitting it

Hello list I've installed cluster suite with 8 physical nodes, these are connected to a SAN using CLVM and AOE protocol. The cluster suite runs on the physical nodes/servers, in dom0. If I have to use GFS, where do I install this? What is the right approach to using GFS with Xen. I see 2 options: 1. I install GFS inside each domU (unprivileged domain, the actual VM). 2. I install GFS on

Hi, I posted this question to the OpenBSD bugs list last week, however I have had no reply and it was suggested on IRC that I post here instead. So I must apologise if this is not appropriate. For a reference here is my previous post: https://marc.info/?l=openbsd-bugs&m=156080681530337&w=2 I am running OpenBSD 6.5-stable (also tested on -current). When I ssh somewhere I get a sig abort

Hello all, At our office a have a server running 3 Xen domains. Mail server, etc. I want to make this setup more redundant. There are a few howtos on the combination of Xen, DRBD, and heartbeat. That is probably the best way. Another option I am looking at is a piece of shared storage, a machine running CentOS with a large software RAID 5 array. What is the best means of sharing the storage?

Great information, thank you. Could you remark on GPFS services hosting mail storage over a WAN between two geographically separated data centers? ----- Reply message ----- From: "Jan-Frode Myklebust" <janfrode at tanso.net> To: "Stan Hoeppner" <stan at hardwarefreak.com> Cc: "Timo Sirainen" <tss at iki.fi>, <dovecot at dovecot.org> Subject:

Hello: I am planning to implement GFS for my university as a summer project. I have 10 servers each with SAN disks attached. I will be reading and writing many files for professor's research projects. Each file can be anywhere from 1k to 120GB (fluid dynamic research images). The 10 servers will be using NIC bonding (1GB/network). So, would GFS be ideal for this? I have been reading a lot

I'm looking at using GFS for parallel access to shared storage, most likely an iSCSI resource. It will most likely work just fine but I am curious if folks are using anything with fewer system requisites (e.g. installing and configuring the Cluster Suite). Specifically to our case, we have 50 nodes running in-house code (some in Java, some in C) which (among other things) receives JPGs,

Hi, Can anyone shed light on Linux's Global File System in RHEL 4 please? It looks like Oracle's OCFS. Is there any relationship between them? If they are different things, has anyone done any performance comparison please? Thanks and regards. Han -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with
